what sort of price to turbo 1.6 urself?

[Cheeze]

as above, would prob be getting engine rebuilt as its done 125,000 so it needs it, let me know plz

[geordie_racer]

bout 3.5k for a decent reliable setup prob a little bit more, thats based on a 1.6 16v can't see the 8v been much cheaper either, really depends on look in gettin parts. a bad bodge job could be done for around 1k if not less with luck but i certainly wouldn't want to drive it or live with it

[Cheeze]

yeah i though that, i know courtney do it for 3k, but using a micro switch to fool the ecu or something, any1 shed light onto this where is it linked to for the vacuum, and where into the wiring??

[m.d.]

i love it when people say it cant be done for less than 3k.
hows about less than a grand for a safe reliable set up.

you can get a turbo for arround 100 quid second hand. then a carb from a r5 turbo can be bolted to the manifold from an sr with a adaptor plate. both will set you in at arround 100 quid again. then you will have to get the sr manifold match ported to the head which can be done yourself with a die grinder.
right now you have to get the turbo to fit the exhaust manifold. this can be done with another adaptor plate. a little harder to make but not imposible. or you can get one from cortnay. bit dear tho but a lot easier to do.
with the carb and turbo fitted to the head you will need to mount an intercooler to the front valence somewhere. get an r5 one or an rs turbo one and you cant go far wrong. the tubing from the carb to the intercooler and back to the turbo can be taken from various turboed cars from the scrappy. now allthat is left is to run an oil feed from the oil pressure switch with a T piece and a return to the sump. use goodrich braided hoses as it will make it much easier to run them.
now finally you will need to get an exhaust downpipe from an rs turbo or r5 turbo and by a little cutting and welding it can be made to fit under the sump from the turbo. after that you can either make your own exhaust system from escort rs tubing or get a exhaust co to make you one.
you will need to lower the compression ratio so get a 2mm steel spacer lazer cut by using a standard head gasket as a template. there are many companys who can do this. also you will need to put a head gasket both sides of the plate. this is a very reliable way of doing it as i have a friend running 17psi on his zetec escort turbo using a spacer

job done. but that seriously is the cheapest way to do it. you can do the same thing using the injection system but you then get problems with fueling when the boost comes in so you will have to make some kind of 5th injector set up or pay loads for management.

[benji]

if youdo a 1.6 turbo doit propetly like neils. he ran good time's all day today.

[m.d.]

what set up does he have. ive heard that the courtnay conversion is a bit crap cos they use a bodge of a 5th injector system

[benji]

dta management i think.

[geordie_racer]

i can see what md is saying bout using the r5 parts and agrre it can be done fairly cheap this way, the cost i put up is based on using parts like low comp pistons and fully mappable engine management which is the only way id want to do it to be honest. to do it cheap you could use md's method or use a 5th injector and vacuum switch to allow you to keep injection but this is how courteney do theres and it is known to be unreliable.

i think i might have to give md's method a go as i can get a written of r5 cheap enough and a cheap shell to throw it all in may have to be my summer project

what turbo is best to use, for this then guys? also intercoolers and that info needed asap

If its that cheap/easy, why don't we hear about it being done like this more?

[Cheeze]

what turbo is best suited to this? a t2 or something, id rather keep theinjection also, btw its a 1.6 gte

[geordie_racer]

1.6 id say use a t3 from an rs turbo to be honest a t2 would do the job but a t3 would be better.

chris

[m.d.]

snowface: you dont hear of it being done because nobody has a go at doing things themselves anymore. apart from the very few most people just get someone else to do it or will only use ready made kits.

we are just finishing a escort zetec that has been done in the same way as i said but he kept the injuection and used the fiesta rs turbo injection.

this makes me think that there is no reason why you cant use the ignition from an let if you wanted.

[Cheeze]

so a t3 from an escort turbo, 2mm spacer plate to lower compression, intercooler from escort also? make tubing to fit, what about controlling the boost? whats the max i can go, im really interested in doing this, and a dta management to controll extra injector, this right??

[m.d.]

sounds right yeah. start by running arriund 10 psi. thins is done bu using a bleed valve on the turbos waste gate actuator.

[Stuart]

the dta would control the whole engine, not just an extra injecort (although a 5th injector is a homo way of doing it)

?550 approx for that.

[Cheeze]

whats the best way to do it then bud

[geordie_racer]

if your going to use dta management then theres no need to use a 5th injector just get injectors from an let. only need a 5th injector if your not using mappable management and use a microswitch instead to control boost, can buy a 5th injector/microswitch setup from demon tweaks i think then you'd just need a spacer plate 2 headgaskets a turbo and intercooler. and then you just need to put it together

chris

[Stuart]

if you can afford to do it cheap then you can afford to consatntly keep repairing it.

just pay the extra and do it right first time, eg proper low compression pistons, worked head, mappable ecu, decenitish injectors, good turbo + maifold etc.

nova neil is a prime example of how to do it right.

[geordie_racer]

i agree wholeheartedly with cambridge's view if your going to do it then it's worth spending the money and having the best, but i also agree with md that it can be done cheap and with decent results im just not convinced of the reliability of such a setup

Hello,

Here is the link to a BIG thread on this subject... There is lots of useful info you can use from here.

http://www.novaload.net/forums/viewtopic.php?t=67450&highlight=

And here is the link to my car

http://www.novaload.net/features/viewfeature.php?ref=769

Have a close look at the tech-spec and you'll see its not just a case of buying bits and bolting them on (if you do it proper with Engine management). A lot of my bits had to be custom fabricated to fit... Things like the crank sensor, and MK3 Golf throttle body (as DTA needs a variable Potentiometer). So its not easy or cheap... Then DTA needs Mapping..... Which is easily ?400!!!!

I like the idea of using a R5 setup, but a few things have crossed my mind.... Don't the R5 Turbo's use an Oil and Water feed for the Turbo? And isn't the Carb very complex to install as its seems like there are hundreds of tubes and things on them??? You would need someone who knows what there doing to sort it all for you.

The cheapest way I can see to doing it (using the injection), is just to buy a mappable 5th injector... Like an MF2 from Aquamist... This setup allows you to add the extra fuel you require when the car boosts. Granted its no way as good as a fully mappable DTA setup, but its a fraction of the price to install and setup. Then you need to piece together the other parts needed (as previously mentioned) such as Spacer plate, Turbo, Intercooler and mod an exhaust manifold etc etc And your nearly there.

My new ceramic Garrett is water and oil cooled. The standard LET KKK is oil and water cooled as well. Its very easy to plumb in water cooling, you take the top pipe from the rad and take that to the turbo then take the return straight to the header tank simple. Rick

[NovaNeil]

Cool, so you just need someone who's familar with the R5 Carb and your sorted. Someones got to try it.......

[m.d.]

there really is no need to get low com pistons as the spacer is more than satistfactory for car boot presures. the one my mate has on the zetec is safe to over 50 psi of boost. if you go on www.situne.com they have turboed a motorbike engine in allmost the same way as i explained before. well nice bit bit of kit tho.

[NovaNeil]

I been told that the limit on running a spacer isn't the boost pressure it can take (physically), but the way the fuel and air mix's in the chamber under the compression stroke.
I read a book on it a while back on Turbocharging N/A engines, and it said that the Piston (low comp one) are made low comp by hollowing out its centre, so that as the piston comes up under its "compression" stroke, the air and fuel is forced round and over itself due to the shape of the piston (difficult to explain) but basically as you increase boost pressure with a spacer, this effect doesn't happen, therefore the mixture is different and you get a load of problems..... I'll look the book out and quote from it.
But thats why they reckon the limit is around 1 bar of boost (Safe Limit) after that you will get reliablity problems without low comp pistons. Also when I phoned ATC they said the same.

Neil

[Ste_Nova]

what bhp does 1 bar give?

[Funkdocta]

Well peeps, u've definatly enspired me, not with the turbo thing but supercharging. Gonna get myself an old charger from a scrappy or somewhere, or an M45 Eaton if I can afford it and get a couple of 1.4SR carbs make an adaptor plate so they can run twin and bolt it all on???? Then i'll prob just take it to the rolling road and get them to tune it up???

Any advise?

[m.d.]

they will then look at the carbs which you have chosen and laff. as when standard carbs are put under pressure they just squirt fuel out of every orraface. get the carbs from an r5 as they are built to run under pressure

[Funkdocta]

2 x R5 carbs?? Or will 1 b enough?

[m.d.]

ive seen r5s running over 300 bhp on one carb. bearing in mind its what they call a group A carb, not sure what that means. you could use 2 but im not sure what effect that would have. you would have to make a strange manifold. one carb on the standard inlet manifold would be fine tho with an adaptor plate

[Funkdocta]

Has anyone heard of any Supercharging a GTE engine before? I can't find anyone, would like to get some tips and info.
