hey guys, I bought a gsr a while ago and finally got it all apart and to the machine shop. Im getting it bored .20 over and I also ordered a Eagle Rotating Assembly. Im planning on boosting and i didnt want to have too low compression like a 9.1:1 or anything, so i picked up the 10.4:1 pistons in the kit, so i can run a lower boost and get the same hp as low compression and higher boost. Ive just been reading alot lately and im getting nervous about the cylinder walls cracking and what not. im looking for ~300-350 whp. So if you have any insite on this I would appreciate it. I know a great tune is key, and thats all lined up. Im just scared that the block itself wont be sufficient. Thanks
