im looking for street driven 400whp goals here. ive decided on the .63 a/r, now im just worried on the trim. either .57, or .60 im not sure. i want a strong mid and top end.
setup:
b16 head, gsr cams adjustable cam gears
ls block, .20 wiseco pitons 9.3:1, eagle rods, cleavite bearings, type r oil pump, tigged in GE block gaurd.
1000cc precisions. 2.5 ic piping, ssq hks, chuck norris mani.

 

57 trim

 

will the 57 trim have room for more boost if i plan to up it down the line

 

the 57 is going to have a little better response time, but the 60 is going to have a little more top end power. I have the 60 and my GSR is unbuilt. If you plan to go bigger, get the 60, but the 57 would be able to handle it.......
