We're puttign our GSR block back together now, we've pinned the sleeves, have a new crank (the old one got taken out by a bearing), we have eagle H-beam stock length rods, and will be going with some ross pistons, the head is going to be basically stock right now, maybe a little porting for more flow, we want to aim for about 300-325 Bhp in the near future, and then go from there, what is a good comp ratio to go with? 8.5, 8.8, or 9? we're going to be using a t3/t4 setup, we just haven't figured out the exact trim yet, thanks in advance, adn also if anyoen has any suggestins or cmments, feel free to lend them

 

I wouldn't go any lower than 9, unless you wanna feel pretty slow when ur not under boost... just my .02

 

9 - 9.5 will work great for your HP goals and not kill you out of boost...

 

go with 9.5:1

 

I like 10:1, if you have a good tuner, I wouldn't worry running 10:1 CR

also a modified combustion chamber ala endyn mods & rollerwaves wouldn't hurt to reduce detonation problems
