hey guys a quick question.. im going to bore my gsr to 81.5mm and just do a basic rebuild using weisco pistons and pauter rodds.. im wonderous how low of c.r. should i go to run around 15 pounds?

ive seen inlinepro just use oe blocks with their 2mm headgasket and boosted that way to around 325hp.. im looking for around 350.. i was thinking 9.5:1 may be low enough.. or should i run 9.0:1 instead to be safe?

i was gonna stay n/a and sleeve to 84.5mm and build a head but i will spend 2x the money going that route.. i found a place localy that will do the stock rebuild for 1800 with weisco and pauter.. not bad at all i dont think.. i figure just rebuilding and pcing together a decent kit will be much less.. laskey is asking 3450 just for the short block sleeved and built.. thats my rebuild and half my kit..

thanks for the info

 

stay in the 9:1 to 9:5:1 range you should be good.

but your power will depend on your turbo kit
