what kinda power will the blocks and selves hold on a 2.2l should i bore it or keep the stock bore. I now the rods and pistons are rated at 250-300 and the crank at 500. I plan on putting 125shot nos on my cobalt after i change the rods and pistons out. Should i keep the 10.00-1 or drop it down to 8.9-1 i also and gona add the comp cams stage 2 and the 2.4 mini. any other ideas will help i also already have a cai and a header. with 2.5 exhaust

I wouldnt bore the 2.2,

I broke a sleeve on about 18# of boost.

Bored .020 over.

 

you broke the sleeves after you bored it? im upping my boost to hopefully 25 psi and im on stocks sleeves and im gettin worried lol

 

meth is your friend, keep those temps down and those boost levels.

 

hahn 16G on 18PSI...

No sign of detonation..

Broke # 3 & 4 sleeve.

But I just picked up my darton sleeved block from the machine shop yesterday. to fix that!

 

dont drop compression if you are going to use the cams and bigger intake mani...just wasting money at that point..if anything...up the compression
