Ok, i have come to the conclusion that i dont want to set the next land speed record and am just looking for decent streetable power. I am debating between two turbos

T3 60 Trim, .63 a/r housing with 5 bolt pattern, external wastegate,

or

an RB20DET turbo, ball bearing, comparable to a t3, t28.

my concern is the upper rev range, 6000 to 8200. Will these turbos be able to support 8-10lbs all the way to redline?

Also, is 2.5" intercooler piping too big for these turbos?

 

im running a t3 .48/.60 turbo. i hit full boost(6psi) at about 4000rpm ish. and it pulls till the rev limiter......the power used to drop off big time when my wg opened, but that was b/c i had no dumptube on the wg,and it was blowing HOT air(exhaust gases) on my ic . duh

 

i gotta nissan t3 .63 exhaust and .60 compressor. full 10.5psi at 4800 in 2nd gear. pulls hard til redline. the .63 ehaust side is the reason why 4800rpm full boost. on a 99'si b16a

 

go with the T3, you'll be happy

 

.63/.60 t3 fo me
