where can i get a turbo manifold from? and info please

[SRlew]

right where could i get a turbo manifold from to fit a c14se head (sri head)

also i want as much info on turbo's as possible please, maybe a link or if you want to get typing feel free. i want to no what you do with oil pipes etc, also where do the rest of the exhuast system bolt to? as you can tell im not clued up on this turbo lark. but im considering a conversion.

thanks all. lew

[Adam]

Theres a kit for sale in parts for sale.

[Stuart]

same conversion as the 1.6 basically...

if you google something like diy turbo or soemthing similar...

[SRlew]

so the one for a 1.6 will fit?

any link or anything to as much info about them? i have no idea where or what you do with the oil lines etc,

[draper]

whats happening with the t40s youve got then ??

[Stuart]

same conversion as the 1.6 basically...

if you google something like diy turbo or soemthing similar...


:wall::wtf:

[SRlew]

lol sorry stu ;)

draper. im considering using the 40's with the turbo. somthing a bit different like. might sell them to my brother, but i think he's joining me in the turbo route on his xr2. so if i dont use them they will be up for sale.

[Stuart]

id sell the 40's tbh the ball ache of getting them setup to not leak, then get the fuelling done and all that really isnt worth it...

best "easiest" option for a fairly reliable setup (imho) would be
1.4/1.6Mpi inlet (maybe match the ports and smooth a few cast marks out inside)
get a throttle pot on the throttle.
maybe a bigger buterfly
1.6 exhaust manifold with turbo flange (source that somewhere)
turbo obv
oil/water feeds, easy enough from the oil pump and T pieces into the cooling system
mappable ecu.. megasquirt could do it

lower the CR anyway you like but its preferable to do it with pistons...



www.max-boost.co.uk (http://www.max-boost.co.uk) is good for general turbo info.. its LET specific but the principles remain the same

[SRlew]

ah right cheers stu. so you recon it would be hard to run the carbs with a turbo, was thinking of finding a sport airbox (if possible) i still like the idea of it lol

was originaly thinkin of getting an sri engine and starting from that like but a mate mentioned going the carb'd turbo route.

will check out the site now

[Stuart]

you'd have to put the carbs in a sealed box and pressurise it from the outside so that fuel dosent get blown out of the carb backwards etc... if you want a hefty challenege then talk to euro carb or someone like that about turboing them but as said the effort and cost involved you might aswell use EFI and have more power ;)

[SRlew]

so looks like im better off buying an sri or gsi engine. how much wiring has to be done to fit the gsi or sri engine?

[mikey14sr]

If you get one from a corsa or mk3 astra about 5 wires need connecting as they run seperate engine looms.

[Adam]

Just get a MPI inlet,fuel rail, injectors, engine loom,ecu, distributor and bottom pulley.

[Stuart]

your going to need an aftermarket ecu to run the fuel and spark anyway so technically its an entire loom that needs making... oh and thats a piece of wee wee :D

[Adam]

Just make it out of bits of other vauxhall looms,Lol, rip a few looms out of corsa/astras.
And then you could even keep the wire colour coding :p

[SRlew]

right, an entire loom needs making, that doesnt sound easy to me lol

going to see if i can find a conversion guide, see how hard it looks in that, its either turbo my nova or just buy a rs turbo

[Stuart]

dont think there is a "guide" as such for small block GM's.

why oh why are people affraid of looms? they are jsut wires and plugs...... can make on in about a day if going slowly and mincing about.

[Mike]

I agree with Stuar here, looms are a piece of pish!!

Why not just go to www.mvaux.com (http://www.mvaux.com) and source a complete turbo kit through them.

The fit a SRi head to your bottom end, along with GSi injection and ECU then bolt the turbo onto that, get it remapped and hey presto.

Personally id use as 1600 ECU as you'll have better fuelling for a turbo from the off, as oppose to lower fuelling from a 1400 ECU and as a result having to run lower boost ;)

Wether it'll work tho is beyond me! But ive seen a 1400 SRi turbo hit 146bhp at the wheels at well lane turbo with a modified GTE ECU in it?

[Stuart]

DONT buy from Mvaux at the moment!!!!!!!!!!! they used to be great, but have become problematic of recent months

personally if going to the effort of building a turbo engine from an NA item then there is a small ammount of desire to have a good engine... id hope.. so aftermarket management is a must in my eyes (or atleast an MSD remap of the stock ecu, but in essence thats an aftermarket remap on a std platform)

not saying you have to but id want the very best from an engine without nessecaraly cutting corners, so id hope others would too lol

146 @ the wheels from a 1.4 turbo.... funk that must have been built properly as neil "only" managed 180bhp (@ the fly iirc) from a full on lower cr piston/DTA etc setup

Baxter was saying that Mvaux took ages with his turbo kit??

Yeh, this guys engine was built better then proplery, im talking no exspense spared!! It was built from a 0 milage brand new GM engine to start with!!

But yes, i too would want the very best from an engine without cutting corners, so aftermarket management is the way forward, but i also know that Lew being around my age, we dont exactly earn millions! lol

[craig green]

I didnt realise Neil had low cr pistons in there. Out of interest anyone know the source of them or manufacturer?

I think Well lanes outputs are sometimes a little optimistic too, not that I'd take anything away from a 1400 8v T. Cheap tax on that mofo dont forget.

[SRlew]

lol your right there i dont earn alot im stuck in a s**ty shop job! wont have insurance for a few months now (before i quit this job) cause i'll have a fair bit money to spend i can afford alot more, well sort of lol

whats the most power anyone has had out of a 1.6 turbo (gsi/gte)

[Stuart]

MS is ohh ?200 inc all the bits if you DIY ;) a modded GSI ecu is gonna cost about the same and be limited in its use..

[Stuart]

id say a properly built decent specced 1.6 8v Turbo should easily be able to make 200bhp with not too much lag etc.. if you want mroe power i belive you will have to have it at a sacrifice of more lag unless you spend a mint on a funky turbo.

but the key with turbo engines is setup and mapping, and that is a cost that is totally unknown fully.... ie from ?200-5000000000000 (ok exagerated but you get the gist)

[craig green]

My GSi had the little T2 that suited it so well. The turbo spooled from almost tick over & the torque from below 2k rpm was awesome. From a standing start was where it really thrived. Cant actually think of any traffic light GP I lost. Sure it ran out of breath at high revs but 8v 1600s dont rev particularly well as a std lump anyway, but the extra torque was worth it.

So many people I took out in it thought it had amazing power delivery for what it was. I definately know that I will have to have another smallblock Nova turbo soon.

yer i want somthing around the 200bhp mark. was looking a t34 turbo's but they come with a bit more lag i believe.

[Stuart]

a T34 would be overkill imho...

you need to read up on how to understand a compressor map etc. Ive got a cracking article on turbo speccing from Fast Ford.. ill scan it in at some point (no scanner at home).

[Mike]

i wouldnt use a T34 either tbh, its way to big for a small block! Hence its use on an Escort Cossie, big block engine.

T5 should be fine, wouldnt give that much lag at all tbh and spin up pretty much straight away

Then jus trawl ebay for a FMIC or use a cooler from a Range Rover sport or transit TDi

[Mike]

By the way, Omega Pistons Number is - 0121 559 6778

they do low comp ;)

[craig green]

I wanted to use a T25 on the tubular manifold from Mvaux..

Damn you Mattheus!

Prertty sure they wont make them for a Nova 1600. Ive asked.

There commmonly used on RS Turbos arnt they? If they are, getting a used one shouldnt be to hard really

[Mike]

thats why ive got the phone number ;)

[Stuart]

lol.

id be inclined to use a chargecooler for a decent spec turbo conversion... but they are traditonally a tad more cash than a simple FMIC (but yes the NEW transit FMIC is good and quite short but it is wide)

a T25 with the right housings should be ideal for a good spec 180-200bhp 1.6 8v engine. slip in say a B+ 1.4/1.6 mpi head and a cam with MINIMAL overlap (might need a custom grind but catcams do those for the same cost as a normal cam) and you should be laughing :D

[Mike]

but getting a "universal" so to speak charge cooler will be a lot harder then getting a normal cooler, espicially if you get it off ebay tho

And then theres the money! But yes, if your going big spec, charge cooler would be a lot better!

[craig green]

step 1. Buy one of these (if not both) books. http://www.amazon.co.uk/s/ref=nb_ss_b/026-6199475-7698813?url=search-alias%3Dstripbooks&field-keywords=forced+induction

step 2. Buy an engine stand & put the block on it.

step 3. Choose a turbo charger & purchase it (ideally new) not ebay scamcharger.

step 4. Approach local TIG welder to make a tubular manifold.

T3 which Ive been told would be not much use on a 1600 Nova. (by Chip)

KKK16 from a LET would be good if it wasnt part of a gay manifold.
