what do you think, Pr3 pistons or the ctr pistons for my b18c n/a buildup? I will be running on 91 octane and was thinking of what would be more suitable, i know lots of people use the ctr's but the pr3s also raise the compresion to a decent amout also.

anybody?

 

just go ctr you should be ok on 91octane

 

if you want to be conservative get the JDM P30 pistons... it will yield a higher compression ratio than the PR3 but lower than CTR

 

I'd personally go with CTR overbore, but make sure you have a hondata and know what you are doing!

 

would the ctr overbored pistons yield a lower compression ratio or is it the same as a standard bore?

 

it would be a little higher than standard bore, not much tho

 

I thought CTRs in a b18c1 with cams causes a valve/piston clearance issue......I wanted to go with CTRs, but wasn't sure if my sk2 stage 2s would cause this issue...

If he isn't planning on ever doing cams, ignore this

 

JDM P30s or JDM ITR

I'd go with something that you could tune yourself with a VAFC unless you have money set aside to pay someone to tune it.

oh really maybe you should research this

 

thats why i have you wonderful experienced people that could help me
could either the type r pistons be able to handle the high compression and something such as a 75 shot of nitrous well?
