im getting a custom turbo kit made and i was wondering on how big to make the turbo
it's for a b series
when i'm done with the car i'm looking for 500whp

the turbo is a t4e 60 trim
.63ar exhaust
stage 5 turbine wheel
should i go with a 60 or 70 compressor housing?

 

for what b-series engine? if its a b16 like im guessing it is by your sig and username... you're ganna have to pump some major psi into that baby. but if you really wanna try it id say 70 trim.

 

sleeved b18c block with crower rods and je 9:1 pistons with a b16 head(the block and parts are on the way)
