What do you say mates?

Which turbo is the best for the S2? The engine is still 1.6l.

all depends on the rest of your engine, different turbo for different specs, got to take into account the airflow, how you want the car to drive, fast boosting or loads of boost more lagg etc, different exhaust housing/compressor wheels/etc etc. Speak to vince at cr turbo's and he can spec you one to go with what you want and the rest of your engine

If it's a standard engine/management, and if you intend to keep it 200bhp or less, i'd go for a standard turbo but put a 0.48 exhaust housing on it with a -31 and suitable chip/intercooler.

stage 3 t3 maybee

Rick

if it's 200hp or less, you certainly don't want a 0.48 housing on it.

pa_sjo

I guess that depends if you like doing things properly. The standard turbo gets inefficient over 185bhp, so I prefer to do the right thing and run a larger turbine housing. You're not going to get a genuine 200bhp on a standard engine with a .36

Butchi

Thanks for your answeres.

I have a kent cam cvh 34. Im going to build a charge cooler instead of the regular intercooler, but my charge cooler will be more effective than the one on the market. The air intake will be in the front, not in in the engine area. I want cold air in the engine. chiped ecu with upgraded fuel ecu is in the car now.

I was thinking of buying a tubular manifold from the ebay http://cgi.ebay.co.uk/Ford-1-6-CVH-e...3286.m20.l1116 but then I have to use a different turbo.

I want 200 horse power in the end of my building. I have a brand new clutch that is stronger than the original.

Magnesium wheels that doesent weight something at all.

maybe I buy MS in the future too.

I'd definately go for a .48, and if you intend to go above about 220bhp in the future then i'd seriously consider a larger compressor too (eg, 50 or 55 trim)..

Butchi

So a original T3 has a .36 housing. Which is the different between a original and a stage 3 t3 than?

pa_sjo

A 'stage 3' typically has a 0.48 exhaust housing with a 50 or 55 trim compressor. It's good for about 250bhp on a CVH.

Rick

ABove 185, you're starting to push things out of the compressor map on a std T3, but with a half decent intercooler this shouldn't be an issue. There is no way a 1600 needs a 0.48 housing for 200hp. All you are doing is compressing the powerband. There is a touch to be gained at the top end granted, but it's a poor mod unless it's a track car.

The best road turbo would be the Stage 2, which gives you a 55 trim 2ed cossie compressor and 360 thrust. These turbos will give 215hp on a std engine other than cam and cooler. If you go for a proper cylinder head, you can ring 240hp out of them, with lots of torque and a nice broad power curve.

Rick, how about exhaust temps with .36 exhaust housing and this stage 2 compressor wheel..?
What you say if i would drive absolut standard turbo with proper ic and 15 psi of boost.
I have programmable EFI naturally, standard head and cvh 35 cam properly timed.

pa_sjo

Rick, i'm not even going to bother asking for your test results of TIP and EGT that made you come to the above conclusions.

My opinion stands

Rick

EGT's rarely over 500C at the down pipe, so 700 ish turbo. It's much the same as running a T34 on a YB ar 33psi, or a 500 T4 engine. You are according to theory out of the turbo's power range. However, in practise it works. I've has my own RST for 9 years, a daily driver untl last March, and it has never melted anything. 0.48's on 1600's are laggy - i know as i've got one and mapped lots. It's just not worth the sacrifices on a 200hp engine.

Antii, exhaust temps aren't worth worrying about once the car is mapped properly on a bar of boost. The std turbo will work at 15psi, but it's working hard, and it's life will be shortened. However, this is what the majority of chipped RST's are, and have been for 20 years. If you can spare the cash, go for a stage 2 turbo. A little more power, and it isn't spinning as fast. Will last too, Turbo Technics are comforable with theirs upto 22psi.

Antti O

Thanks for proper reply. I have been thinking something like garret GT2560RS or GT28RS with small exhaust hosing. But bigger turbo comes after next spring i think, winter my rst will go garage and i will change koni adjustable´s and polybushes & cosworth brakes.

Tony Turbo

You tell him, Rick

project rs

you go rick about time we had some proper answers with facts to back it up.

pa_sjo

I think i'll listen to the advice and experience of the first person to ever chip an rs turbo than forum blah....

uck me he must be old now!
