Anybody using a T4 turbo. P-trim wheel .58 or .69 a/r?
how quick it spool? powerband, etc.

 

You can run a T4 exhaust with a P-trim wheel and a .58 A/R housing with a 50 trim TO4E wheel. You can run a T4 exhaust with a P-trim wheel and a .58 A/R housing with a 76mm T-series wheel. Question is way too vague.

 

is anybody running a straight t4 with p-trim on the b18's engine?
where/how the spool and full boost at which rpm?
Cause I have a t4 turbo.
P-trim
and don't know the compessor wheel but i think it's a 75-76 trim wheel, with .50 a/r

 

Unbolt the turbo compressor housing, measure the inducer and exducer, then we can tell you what kind of a turbo.
