I have a 2001 GSR. My setup right now is:
Skunk2 Type R style intake manifold
Type R AEM CAI
JUN Type 3 Cams, valvesprings and titanium retainers
DC Sports 4-1 CC Header
Type R Catback exhaust with 2.5 inch cat
2000 ITR ECU
VAFC

This weekend I will be installing JDM ITR Pistons (11:1) in a GSR block that equivalates to about 11:8 or 12:0 compression. The rods are shotpeened. My question is should i be close to 200 Whp and 130 pds of torque. My goal is to also get into the 13's (with slicks). Whats your guys opinions. I nearly gace up on the JUN cams, but it was my error due to the fact I thought they would just slap in and give me horespower. Those cams require at least 11:1 compression, as they bleed off compression, and in a GSR the stock pistons just dont cut it.

 

also my FPR is set at 50 with the line off

 

You need to bump the pressure to around 65psi with line off, plugged.

I doubt you will be at 200whp, probably around 190whp. You should be in the 13s with less mods than you described.
