Hi there, can anyone tell me if the turbine wheel on the big turbo escort cosworths are stage 1 i.e. same as the turbines on t3 4wd saph cosworths, or are they stage 3, as they seem to be able to hold a lot of boost??

A T34 Compressor housing, back plate, and compressor wheel are different to any other Cosworth T3 Turbo.

 

same wheel stage 0ne

 

Anyone know what is the EsCos T34 compressor A/R? Sierra Cossie T3 has .42 A/R compressor housing so I'm wondering how big is the EsCos compressor then.

 

2wd cos t3 and 4x4 t3 use .42 ar but the 4x4 has a 60 trim compressor wheel/ 2wd = 55 trim = a 2wd compressor housing will not fit a 4x4 t3 wheel.

The ar for a t34 compressor housing is .60

all t3 and t34 have trhe same size turbine wheel.
