what would fitting standard bore ctr psitons raise it to ?
and what would .25 ctr psitons raise it to ?

i wanna get to 11 - 11:1 and wanna use oem headgasket. car is daily driver and MUST remain just as reliable.

am running type r cams at the mo but goin for jun 3. have all usual breathing mods on already

 

help me

 

There was a previous post that stated the compression of CTRs for all applications. If my memory serves me correctly, the compression of CTR pistons in a b16a2 stock bore is around 11.5 ish or a little higher so .25 over bore will be a little higher then that. 11.5 is still streetable with good tuning

 

, thats just what i wanted to hear, cant find that post though

DIY . Seriously though bookmark this site

 

10.8:1

 

, didnt really wanna go for thinner headgasket but looks like i might have to now

 

Spoon makes a two layer that is only 125 bux or something like that. Also Mugen has a single layer if you wanna get serious.

 

yeh i know, just didnt fancy payin that kinda money for a headgasket. extra **** always comes up when you plan somethin with cars
