Hello, was wondering if someone can help me... i am building a rwd Opel car and installing a Cosworth turbo engine. I have the engine already, t5 box etc BUT i have yet to buy a turbo. The engine is a 200 block, group a haedgasket, greens, 3 bar map sensor and a motorsport chip.

I am looking for low down power rather than top end speed, as it will be a track car in the end. Which turbo should i look for ? I am not big into turbo's so any help would be appreciated. I can buy a big turbo from an escort cosworth with cut back blades and a 360 trust washer, though have been told to get a 360 roller bearing type. Whats the difference ???

Also, should i go for a .48, or a .55 exhaust housing or some other type. Also, i am using a 2wd turbo exhaust manifold.. will i gain anything if i go for a 1 piece 4wd one...


any help will be appreciated... brian

Well a T34 is about as big as you'd want to go on greens.. .48 turbine housing is fine for this power level.

Cheers, though wot about the difference between the thrust washer type and the 360 degree bearing type ???
