and bolts on to SR20DET manifolds and downpipes.
Internal Wastegate.



JGYBB37R - TO4B Compressor housing with 56 trim T04S
compressor wheel. 55lbs/min air flow. .86 AR T2 exhaust

Rob the turbo isnt a T04...its a large T-28, its just using the T04 compressor housing :wink:

Turbo #1 on that list will make boost around 3500-4000rpm.

Turbo #2...expect another 500-1000rpm of lag so look for boost around 4500-5000rpm.

These figures are conservative, you should make boost some where inbetween these numbers
