My First Nova, 1.2 Turbo conversion

[Technicalsteve]

Hey people.

I became a Nova owner about 1 month ago, when I hit a Nova up the **** in the Misses car. Not making any damage to the misses car, but wrecking the nova (dented floor pan, bumper, boot etc etc). so instead of going to the insurance company I offered to buy the car off of them. Well after ?100 notes changed hands I was a proud owner of a Nova 1.2 star :-) with a dent.

Got the nova home and gave it a good look over. The chassis was straight still and looked like only a small amount of work was needed to push it back out. So one saturday armed with a Jack and some wood 4" x 4". One hour later the car was all pushed out and looking right. Still have one dent in the floor but hey.

So as it cost me 100 notes I thought have some fun :-). Stripped the car out, and started to plan for some mods so I can have a laugh in the STAR.

So after stripping it, Cutting the dash about to make it smaller and lighter I started to pick up bits for my project.

Looking in the garage I found an old 306 DTI turbo, and thats when I stated to think :-) :-) lol

Yes thats right she will be a 1.2 turbo. Not really sure how long she will last as im not going to lower compresion or play with the engine apart from a R5 GT carb, Small front mount intercooler and induction kit.

At the moment im just finishing of some mods to the seat frames as a friend of mine owns his own seat making company, cheap fibre glass seat that is so light (1.6kg) yes one and half bags of sugar. once thats done I can get the car out fit my lowering kit and remove the exhaust ready for the turbo mount to be made.

Im on a budget of ?500 including the car, see my list below for required parts etc, any help would be great. Thoughts are very welcome, and pics will come soon. :-)

Parts list

Car = ?100 GOT
Lowering kit = ?55 GOT
Bucket seat = ?100 GOT
Full harnesses = ?35 GOT
Wheels (astra GTE) = ?40 Kind of got, if not then already have Corsa SXI
Turbo, exhaust pipes, intercooler pipes, = FREE GOT
Rally sparco/omp steering wheel = ?60 inc boss NEED THIS
R5 GT carb = ?30 NEED THIS
Few other bits, cables etc etc = ?80 not sure what yet but always get this kind of things popping up that you need

Not sure if this has ever been done before but hey, will see what happens. If the engine goes then a 1.4 SR will going in with 5sp gearbox then turbo bolted on again :-) next time do some head work to lower the compression.

thanks for reading

Talk soon

Nice one steve, have you got any pics of it as it is? Also whereabout in kent are you as im from maidstone.

Anyway good luck with it and keep us updated. :thumb:

[Paul]

By Borstal are you?

Sound slike an interesting project!

[Welsh Dan]

Sounds like a good plan, apart from the fact that the Diesel turbo might not cope with the exhaust temperature from a petrol engine. You might be better off scrounging a small petrol turbo from a saab or suchlike in a scrapyard.

[Technicalsteve]

Walderslade Woods Area.

Interesting is one word, lol.

Its my first car that im doing on my own, but my dad is giving advice (his a motor expert for midkent)

Yeah I know, but worth a try as its sitting in the garage :-) If it goes bad then next engine, petrol turbo lol.

I forgot to say the exhaust is coming out the side :-) will be ace, real tatty but quick lol

[Adam]

And a diesel turbo is designed for a diesel engine. And you'llneed to someone make a manifold and suitable flange to fit that turbo... T2 flanges are readily available.

Get a cheap t2(for like ?30) and use that.

[Jack]

Early derv 306's used a T2 :p

Although most are KKK iirc.

Boost to about 12-ish psi in standard form I think.

The turbo will be welded on the manifold, if thats a problem then I plan on making 1flange to weld in the down pipe..

Just play about and see lol

Think its a KKK, thats what I had on my old 306 TDI, had this turbo as a spare to play about with.

Thanks tho :-)

[Steve]

Ahh yes walderslade, interesting indeed lol you know laker road then I take it?

Theres a couple of people on here from rainham as well although I still dont see many novas out on the roads around here!

Good luck with the project steve, be good to see how how it turns out.

[CP]

Novel conversion - good luck with it:)

[Stuart]

even a diesel spec T2 wont take petrol combustion temps for long.... mmm melty.

and the gm TD manifold wont mate to the petrol head either.. just get an adaptor made to go on the cast manifold to a suitable turbo. easy then.

I'm in Lordswood, right next to ya.

Would be interested in having a nose nearer the time ;) :thumb:

I think ive been up laker once in my Cupra R. I sold my last project to a guy that goes up laker. It was a blue/green 205 cti. 1.9 Leather seats, propper mint (as it took me a year to restore it)

http://i218.photobucket.com/albums/cc72/cupra_duper/French%20Car%20Show/IMG_0592.jpg

Think that was the best car ive ever had. Low tech, but so much fun

[Mazz]

Interesting conversion dude! Should be a giggle when its done.
The obnly other 1.2 turbo i've seen was a 16v one : http://www.pngclub.com/forum/viewfeaturecar.php?ref=2492

[craig green]

A friend of mine turbo'd a 1200 Nova years ago. Used T3 from a Metro turbo & the metro carb. It went very well despite no intercooler. No drop in compression either.

Not bad thinking, will look on ebay for metro turbo bits.

Think it will be fun once its done. Will get some pics later this weekend

Quick Update

Hey people.
Just wanted to add a quick update but no pics as yet :-(
Fitted the new bucket seat are welding up a frame, Fitted new Full harness, Fitted rear lowering kit, Fitted New Corsa SXI wheels (not the best but will be ok for road tests). tried to fit the front lowering kit and all went wrong. the kit was a mess so cant use it :-( Looking for some new front springs + shocks Complete would be good.

Exhaust is off + Manifold for lining up the turbo ready for the adapter plates to be welded.

Got to find a nice place for the intercooler, then source a R5 carb (maybe metro turbo)

Side exit exhaust needs finishing once the car has been tested for noise but waiting on the turbo.

Few weeks and we should be kicking :-) or blowing up either way I will be getting some pics uploaded ASAP (should of taken some at the weekend but couldnt be ****d lol) tonight I will get in the garage and take some.

Any pointers are welcome, remember im on a budget (due to it being a laugh project)

[Technicalsteve]

Just a quick Update.

Not done much as ive been doing other things.
Turbo is nearly done, only problem being I lost all the exhaust bits so looking for a new 306 tdi downpipe. (if anyone has one) only need the front bit.

Im hoping to have the turbo fitted this weekend, but havent found any carb bits as yet. so if anyone has metro carb let me know.

Cheers
Steve

P.S pics will be this weekend :-)

[Technicalsteve]

Well I gave up trying to make a new manifold due to the cost and time. Instead I made a plate that bolts on to the normal 1.2 manifold and lets you bolt the turbo straight on. Bit tight in places but fits really well.

Would like to thank my dad for helping with plate and making me an new down pipe for the exhaust (still in the making)

See pics below.

Hope to get this finished soon as I stopped work due to other things going on.

Check out my bits for sale (all free) as I dont want them laying around.

Cheers
Steve

[Lee]

lmfao, fair play for having a play with it pal. Do you not think its worth sticking two headgaskets on just to drop the CR slightly, give it a bit more of a chance of success :)

[craig green]

Is the oil return going to be high enough to enter the sump pan above the oil level?

Nice to see someone actually doing a conversion though. Keep at it.

[Technicalsteve]

Yeah I did think about that, but will see how it runs first. Might end up putting a 1.6 in with a couple of headgaskets lol.

Will keep people up to speed when it happens

[Technicalsteve]

To be honest I have no idea. Im sure it will be fine or made to be fine (on a very low budget) lol.

Thanks for the comments, only doing it for a laugh as I had the bits laying around

[craig green]

Well just a heads up, mount the oil return as high as is possible in the sump, file into the upper lip to gain every last milimetre. If the oil cant flow into the sump, the turbo will smoke like crazy.

Will do, thanks for the info/help.

[big gra]

haha very interesting project, lets hope it works.

[Adam]

Just what i was thinking, the turbos sitting to low due to using a standard exhaust manifold

[Technicalsteve]

I dont think it should be a huge problem, but will keep it in mind.

Getting the manifold sandblasted and painted today. Picked up some copper plate to make gaskets and picking up the exhaust elbow.

Need to drain oil and take the sump off to drill oil return hole.

[DW-Nova]

any progress been made recentley mate?

[Technicalsteve]

Hey people,

havent done a great deal as ive been doing House projects :-), so currently splitting my free time with the games room, Nova turbo and my jump bikes....

Anyway, I have now sand blasted the manifold, downpipe and turbo elbow. painted the manifold Gloss black same as the elbow.

All oil pipes are ready, so the sump has to come off ready for the feeds etc.

Then its put it all together and see what happenes. Have to change the wastegate screw as its currently pushing 1.2 bar (306 tdi standard) and I think 0.2 bar would be good enough for the mo.

thinking about making a top plate for the carb, but for the mean time im going to use the air filter case, remove the air filter and make sure its all air tight.

That way i know it will start up, run for a bit and find any problems.

Will try and get some pics this weekend so people can have a nose.

Once its done I will chuck it on the rolling road so people can know the figures.

Already found my next project :-). Going back to the french with a bit of jap im the back. (pug 205 1.4 5 door. remove the 1.4 engine, cut the rear floor out and replace with a 2.5 turbo from a subaru sitting in the middle) Should be fun, and once again its all stuff I have laying around so cheap as chips.

[DW-Nova]

Sounds good! do you have a suitable carb for the car?

[Technicalsteve]

using the one thats on it for the mo, then might go up to a 1.4 sr or R5 carb if I get problems.

[craig green]

Metro turbo carb FTW!

[ck]

if you have a twin choke manifold it shoudl be way easier to mount a renault 5 turbo carb. it sits verticaly just like std as opposed to a metro turbo SU carb which mounts horizontaly. just thinking it will be alot easier with the R5 carb tbh..

[craig green]

Fair play. I actually know nil about the Metro carb, other than my mate did a 1.3 SR turbo about 12 years ago using all Metro bits.

[DW-Nova]

Should be really good if it works, tbh i dont think the standard carb is going to cope imo, it'll run dodgy as with it on, is it hard to find r5 gt bits? dont really know anything about them, anyway gonna go and do some work on my car, best of luck.

[~~joycey~~]

Good luck :thumb:

[Rickyb]

Any Updates On This?

[amggsi]

Early derv 306's used a T2 :p

Although most are KKK iirc.

Boost to about 12-ish psi in standard form I think.

15 standard, but can be pushed to 30ish before they start popping daily!!!


I was nearly able to change turbos in my old 306 blindfolded!!!lol

[Gibbo]

so can you put a turbo on any engine.? if so wot do you need to do?


nice work on car mate:)

[DaveyLC]

What are you going to do about timing? If you get a vacum module from an old Saab turbo you might be able to make something up.

[DaveyLC]

so can you put a turbo on any engine.? if so wot do you need to do?


nice work on car mate:)

You need to drop the compression ratio, alter the 'on boost' fueling and allow for the correct timing retard/advance..

[burgo]

you dont NEED to drop the compression ratio at all. you just have a uch bigger safety margin if you do

[Gibbo]

what about the headgasket ect,,,

[Mike]

^ what about it?

[turbojolt]

what manifold did you use to bolt the turbo to

[Gibbo]

^ what about it?

dont you have to change it or anythink

[craig green]

All this banter about general turbocharging is another subject entirely!

[Technicalsteve]

Sorry for the delay, been busy doing other things so havent had time to get on here.

Ok all the down pipe is done, sump oil drain done and sump re fitted. had to move the turbo a bit on the manifold as the oil filter was hitting. Anyway im just trying to hind a T bit for the oil pressure switch so I can get oil in the turbo, Hope to do this at the weekend if not before. once thats done i will start it up (before any inlet pipes are connected) just to make sure it runs and the turbo spins etc etc.

Im not planning on changing the timing, head gaskets or compression. Will get some pics up here tonight for you guys.

Hoping to get it finished soon.

[Technicalsteve]

what manifold did you use to bolt the turbo to

The standard manifold, with some small mods and some madness. In an ideal world the turbo would be closer to the engine, but again in an ideal world i wouldnt be using a turbo from a 306 TDI or a 1.2 engine. Its all stuff I had laying around and wanted a laugh. :-)

[Rickyb]

good on you pall :thumb:

[Technicalsteve]

Sorry for the delay, internet at home stopped working and yesterday I forgot my camera (dam it). Anyway I have uploaded them this morning. Enjoy.....

(p.s dont comment on the welding it wasnt me...) Cheers tho dad even if it does look like chicken......

[bola]

cant wait to see this finished!

[Rickyb]

gettin there now buddy

[draper]

the weldings not that bad imo

any idea when we'll have a vid of it runing ;)

[Andy]

I always say this to people-who cares what the welding looks like? most of the time its never seen and as long as its penetrated the metals and in the case of an exhaust formed a good seal then does it really matter that much?
Looks good mate keep it up.

[DW-Nova]

looks really good mate, especiallly considering that it's just a botch up with some bits that you had lying around, have you made a top hat adatpter plate for the carb or something? i reckon it should go pretty well once it's finished, have you started it up yet?

[Technicalsteve]

the weldings not that bad imo

any idea when we'll have a vid of it runing ;)

Still trying to find a T bit for the old feed. might end up making one, once thats gone i will start it to make sure the turbo spins etc. Then i have to do the inlet. I think i will make a vid on the first turn over, just before it all goes bang lol

[Technicalsteve]

Ive not made the Adapter as yet, was going to seal the air box and use it like that for my tests, then make a new adapter using the box as a template. see what happens, has to be a botch up as they always seem to work well lol.

Will get some more work down next week i hope as i have the week off work, saying that i need to purchase a new car (as my LCR is sold) and i have to lay foundations for my games room. will try and get it done asap.

[dg225]

nice little project keep up the good work..

[General Baxter]

thats going to smoke its tits off, the return needs to be alot higher

[Technicalsteve]

well people here is the first video of it starting up.

It doesnt show the sound (think my camera was crao for the sound) as it give a nice racing turbo sound from the exhuast, Just got to link all the intake stuff up so it can go on the road. :-).

http://s218.photobucket.com/albums/cc72/cupra_duper/?action=view&current=MVI_2065.flv

Let me know what you think people.

[Technicalsteve]

thats going to smoke its tits off, the return needs to be alot higher

Didnt seem to smoke when i started it, will let you know on a road test. If it does i will just shorten the pipe and angle it.

[Steve]

Sounded ok mate, idle maybe a bit rough but glad to hear you got it running, might have to pop up and see it once you've got it on the road.

[CorsaBBoomer]

Nice to see this running and respect for trying this setup :thumb:

[robertdevlin69]

nice,that would make an animal sleeper good luck wit it

[C14se]

looks like you will be having some fun with it than lol

[DW-Nova]

brilliant, i bet it's made you feel 100% more positive once the car started up for the first time, seem to run alright too! i dont think it should smoke to be honest, it looks alright to me, cant wait to see this car driving.

[belly257]

looking good mate, sounds well :thumb:

[Technicalsteve]

Going to MOT it in a weeks time before connecting up the inlet, just incase the turbo throws out the emissions.

Apart from that I have to make the inlet plate as my air box idea didnt work out :-(, but to save on pipe work im going to put the intercooler on top of the engine and just cut a hole in the bonnet.

Still work in progress but should be running so as the hard work is done.

Thanks for the comments

[Rickyb]

any updates dude:thumb:

[rodgers]

lol thats ****ing ace! well want to see this go!

[Technicalsteve]

No updates as yet baring ive made the plate for the carb. Been busy doing my house + fabia VRS. I plan on getting this done soon tho as everyone wants to see it go. Once the pipe is done for the carb its all ready to go, shouldnt be to long :-)

[Steve]

Glad to hear its still going, had forgotten about this.

[Adam_J]

where will you connect the oil feed from? i didnt think there was anywhere you could just 't' into for feed pressure imo???

Good effort though good to see someone giving it a go should be interesting to see the result:)

[*Dave*]

sweet project !! massive respect for this.

im only in rainham with a few other nova boys. will have to meet us some day.

and i have seen your old 205 cabrolet up laker road before.

steve from maidstone is a dude!! could pop up wit him some day.

cheers.

Got the oil feed from the oil pressure switch, all works fine (tried and tested). my dad is a legend when it comes to cars and knows his sh1t so shouldnt be a problem.

I do miss my 205 cab, but think I miss my Leon Cupra R more. Saying that the Fabia VRS is now de catted and soon to be revo'd up to 180 bhp :-).

[Tidy Max]

i want to see the figures for this little beast! sounds like you have a 30 hour day mate, do you actually sleep or just build different projects lol, laying foundations, nova turbo, fabia vrs haha

[Technicalsteve]

I have no idea what the firgures will be, hope they will be about 130 ish, but might be expecting to much out of the little shed lol.

Tell me about it, I work full time in the City so thats a minimum of 12 hours a day. hence why this is taking a little longer than I wanted :-(.

[DW-Nova]

Alright there mate, not checked back on this one in ages, hows the project coming along? did you manage to get the inlet and top mount cooler all fitted up yet?

[Technicalsteve]

Alright there mate, not checked back on this one in ages, hows the project coming along? did you manage to get the inlet and top mount cooler all fitted up yet?

Its not come along much :-( due to my lack of time. Im on the case tho so should be finished soon. Made the plate for the carb, just need to weld it together and fit some pipes on it.

Not 100% sure i will run the intercooler now as the one i have is huge. Might see if i can get a smaller one off a standard car. will see what i can get for free :-)

[Technicalsteve]

whats that!!! how have you pressurised the float chamber aswell?

[Technicalsteve]

whats that!!! how have you pressurised the float chamber aswell?

I have to say that people on this site do know there stuff, very impressed.

to be honest I dont know how im going to do that yet lol, will see what happens.

the inlet is made up from 2 bits of flat plate, with an exhaust pipe welded in. fits nice :-). will be painted so it wont look so ruff

[Southie]

This is gonna be an interesting outcome good or bad. Hope it don't blow up but if it does make sure your filming it at the time :)

The turbo inlet is a fair thing mate it reminded me of my snack at lunch todaylol

http://i345.photobucket.com/albums/p379/SOUTHIE01/vanillasliceyum.jpg

Joking apart really enjoying that you are attempting something that little bit different :thumb: Good man

[craig green]

will be painted so it wont look so ruff

Freshly brazed stuff always looks pants until it gets blasted.

[DW-Nova]

shouldnt be too long till its running on the turbo now eh mate, as regards to the intercooler what kind of size are you looking for ? i might be able to blag you something suitable if your interested ? anything smallish ??

[burgo]

the easiest way to do it steve is encase the whole carb. imagine taking the carb off, putting a cake tin on the manifold then the carb into the tin on the manifold. then put the lid on and your pipe to it. that way the whole thing is pressurised and will work as normal

[Technicalsteve]

shouldnt be too long till its running on the turbo now eh mate, as regards to the intercooler what kind of size are you looking for ? i might be able to blag you something suitable if your interested ? anything smallish ??

yeah any thing small, has to sit along the front so cant have angled in and outs. Was thinking about using a small mini rad as they can take 1bar and i wont be running near that.

the aim of the game is minium cost lol, so anything free or real cheap then its worth a look :-)

That just made me laugh really loud in my office, not good for my hang over. but thats so funny....

[DW-Nova]

Yeh i could blag you something like a nice little passat cooler mate or an astra 4 derv one, they both look pretty good but you'd have to pay for the postage or arrange collection etc..

[Gibbo]

the turbo sounds nice mate

the turbo sounds nice mate

Thanks, will see what it sounds like when its fully done..

Pressurise the whole box, that way the boost pressure will not keep blowing fuel away (****ing the needles or floats) or however it works lol.

That is the way to do it /\/\/\

[burgo]

the way it works is that a carb works by vacuum. the engine litterally sucks the fuel in, therefore when you add positive pressure from a turbo the carb no longer sucks the fuel in. this is why you have to pressurise the float chamber aswell

[DW-Nova]

Yeh i'll try and get you some piccies mate, what kind of sized cooler are you looking for and i'll have a look on the shelf to see what'll best match up for you, you want to top mount then yes?

[BRoadGhost]

Is that a custard slice?

I scrapped the idea of top mount and cutting the bonnet as the pipe work was to close.

Small front mount cooler, flat and long, some thing like this http://i24.ebayimg.com/05/i/001/15/6d/651f_1.JPG

if you cant then I will have to see what I can find laying around my mates house.

Indeed, gives the engine more power.. also makes the exhaust smell nice lol

[DW-Nova]

right mate, i'll have a look at work tommorow for you, what car is that intercooler off in the picture? i'm really keen to see this little turbo going, i think its a great idea and i think it should have a good bit of go !

so whole sealed unit around the carb, sealed by thecarb to manifold bolts, then the induction pipe intot he sealed unit, will work??

[mowgli]

a lot of old carb turbo kits simply sucked the air thru the carb to the turbo.

think that was from a focus. but anything that size, any colour, and any state as long as it works lol.

If you think this is a good project, you will be very impressed with my next one :-). This baby will be used for a few weeks and then sold/scrapped depending how it goes lol.

I have to say I hated novas and really a 205 man, but the people on this forum are so great im going to have to buy another nova....

Glad to hear it mate, us Nova fanatic's are a good bunch :)

[Technicalsteve]

Well the turbo outlet is done, and the intake box is done. Found some pipes for linking it all up so this weekend will have a go and see what happenes :-)

Once you've had a Nova, you're hooked lol

Looks a good job so far, just need to get it finished now :)

[nova_niek]

Once you've had a Nova, you're hooked lol
Too bloody right! :cool: When I bought my first Nova (back in 1991) I considered it a temporary solution to being car-less. But then the modding bug caught me and I've never been the same again since. The first Nova (Red Shed) is still with me, and along came a black GSi which is still with me as well. :thumb:

You've got to love Nova's, you really do.

As for the turbo setup: lots of draw through setups have been done on motorbikes (mostly Kawasaki Z1000's and Suzuki GSX's) in the past. Gradually people moved from draw through (carb first then turbo) to blow through setups (turbo first then carb) as that's a more stable setup, the turbo doesn't have to deal with mixture - air only - and this setup offers the option of intercooling, always nice when compressing air.

Considering you're doing a blow-through setup, there's the following to consider: you want a positive pressure feed (*) from your turbo piping to your float bowl, so fuel doesn't get blown back into the float bowl through the jets AND you want your fuel pressure to be just a few PSI over your boost pressure so fuel can enter the pressurised float bowl.

http://i537.photobucket.com/albums/ff333/nova_niek/nova/various/AIRFEEDTOTURBO.jpg


(*) the positive pressure feed is taken from placing a small diameter pipe, facing the airstream, dead center in the air piping feeding the carb. This gives you an air line delivering just enough to pressurise the float bowl. I hope you understand what I'm on about...

Motorbike carbs are easy for this - they have individual float bowl vents that can be hooked up to a positive pressure feed. Not sure about the carb on your engine. Reading back your post, you've gotten round this by enclosing the carb - right? Sorted. :thumb:
Have fun doing the turbo boogie!

Cheers,
Niek

[Technicalsteve]

People are getting all technical now.... lol

Got the intake box on at the weekend, just pipping up today.

[The Simps]

This is a cool little project!

One thing, shouldn't the oil return to sump flow downwards? You'll be relying on pressure to push that upwards which could blow the seal? Anyone elses thoughts?

[turbojolt]

how much longer do you recon it will take you to finish mate

[C14se]

any news mate

[Technicalsteve]

It has a small down angle so shouldnt be a huge problem. But if it is, then I dont know how to fix it lol, will work that out if it comes to it :-)

[Technicalsteve]

Hope it will be done soon, got to charge my battery, and finish the pipes off. So by the weekend if I can get the pipes done.

Then road test, if it works well I will need to MOT it, Tax it and insure it.

[turbojolt]

are you going to make us all a little video of it moving then mate

[Technicalsteve]

Indeed, First startup will be recorded. And hoping to get some incar videos as well.

Havent finished the exhaust yet so that will still be out the back until its MOT

[Nova_Tek]

Good project mate. Always thought about turboing my 1.2 dont need to now seeing as you are doing it :D

Good luck would like to see the outcome.

Once done you must do a Dyno session mate, get it setup nice and see what it outputs would be really interesting ;)

:thumb:

[DW-Nova]

Hi there mate, do you still need an intercooler ? sorry for not getting back about it but been really busy. sounds as though its going well !

[Technicalsteve]

If possible fella, was going to pipe it up without until I got a small intercooler. If you had one that would be a HUGE help.

Cheers

[turbojolt]

has there been any progress with this lately

[brucer]

only just noticed this project,be cool to see it going.keep it up.

[Technicalsteve]

Hey people.

Sorry for not updating this, I got stuck in to working on my new project (range rover v8 off roader), I found a spare 1 hour today and pipped up the turbo, intlet etc. So all in all she is done and ready to start.

Battery is on charge tonight, meaning tomorrow I will start her for the first time in months. So will my 1.2 turbo run? will it move? Video will be uploaded tomorrow :-)

Let me know what people think, will it run? place your bets now.....

Talk tomorrow.

p.s I havent put an intercooler on it yet, but plan on doing so. Oh I will also run down to halfords tomorrow and get a boost gauge, need to see how much boost she has..

[Spudly]

I reckon you should be fine tbh bud aslong as you dont try and run epic boost on it the engine should take it as theyre pretty srtong engines for what they are, good lukc and keep us posted:thumb:

[dj_wudgey]

nice ive been watching this for a while get some vids up soon pall!!

[EUROTURBO]

very cool, be interesting to see this perform...

[Spudly]

Any joy then was she a runner does it go without a snap crackle and pop??


Is it "nippy" for a 1.2 lol

[Technicalsteve]

She went without the snap crackle and pop. Runs better than before....

Started first time, pushes 0.25 bar, took her for a little drive and its not that bad, needs a fine tune to sort out some over run once you give it some bean. Baring that im well pleased. need to do the following tho..

1) repipe the boost gauge as I melted the pipe :-(,
2) up the boost once the mot is done
3) front mount and intercooler
4) sort out the dump valve, run it without the DV and you get alot of turbo lag.
5) small odds and sods

anyway, a small video of her first start

http://s218.photobucket.com/albums/cc72/cupra_duper/Cupra%20R/?action=view&current=MVI_2335.flv

[General Baxter]

how have you connected the boost gauge up, as it just looks like a rev counter,

you wont have any boost just reving it on the drive way ;) it need to be underload

[Technicalsteve]

I connected the boost pipe in line from the waste gate - turbo. You get more boost on load yes, but it will still show boost when you rev.

like the rev counter idea tho, next time I wont spend my time doing a turbo convserion, just connect a rev counter lol. ,,,,,,

[DW-Nova]

She runs then hey, good one !! just a few niggles to sort out then she's ready to go then hey ? just give us a shout on the cooler mate.

[Technicalsteve]

Yep she does indeed,
Coudnt believe it, small turn of the key, little gas as away she went. Going to play with the boost a bit, to much will stop the petrol going in to the carb, so it knowing the max you can get. will post some better videos after xmas as my camera went dead (my bloody luck). will get some videos of her moving so you guys can hear the mean machine..

will let you know about the cooler after xmas.. thanks again

[EUROTURBO]

it shouldnt,
the bowl should be the same pressure as the boost in the venturi so you should have 0 DP and no reverse flow through the main jet.

either the balance line is blocked or the fuel pump/regulator hasnt got the beans to supply enough fuel against the boost pressure.

[Technicalsteve]

Just at the top of bluebell hill, so not far from yourself

[Southie]

Good work on getting it running Steve :thumb:

Hows my vanilla slice holding out lol

hats off to you mate,sounds sweet for the first start

[Ernie]

sounds nice fella keep up the good work.

[021-bennettt]

Now that i have seen this I really want to do the same to my 1.2 but i just feel like it wouldn't work for me for some reason!
You have a pm

[dougie_boi]

a think if this works well im going to give it a try ive got a turbo and boost pipes other bits from my old cav td lol
