well i have been through 3 websites now searching for the answer to this question.

if i'm gonna be running 6 to 10 lbs of boost on my 00 si with a t3/t4 will i need a 57 trim with a .48 a/r or a .63 a/r.
will a .48 a/r hold 6 to 10 lbs all the way up to 8000 rpm or will it not.because it already has the advantage of the of the faster spool and with that the better throttle response but i need a guy that has tried the .48 and the .63 a/r on a b16 to tell me what he has to say.

keep in mind i will not be changing my internals so i will not up the boost more than 10 lbs. and if anybody finda a link to this question that has been answered completely please share it with me <IMG NAME="icon" SRC="http://images.zeroforum.com/smile/emthup.gif" BORDER="0">

ttt

 

I am using a brand spankin new garrett T3 .50 trim exhaust a/r .48 comp a/r .42

This is considered a small turbo. I make 10 lbs by 4k and it pulls all the way till redline. (7000rpm on LS engine) When I was running unlimited boost I was making around 18 psi in second gear at 7k
