Re: CTR pistons? (Rollo Lawson)
running ctr in my B18c5 for a year now.
with cams and blah blah.
clay'd the piston and there's ENOUGH valve to piston clearance.
and had no problems yet . sooooo..
and the c/r would be 12.5 ish

I have been running CTR pistons in my Type R for over 2 years now. With close to 30,000 miles on an OEM head gasket with zero problems. I know people that put down 500 WHP on boost with OEM head gaskets.

Re: CTR pistons? (crawlin)
my ctr piston'd r is running strong as hell and no signs of detonation... its all in the tuning, plus a bigger cam will bleed off enough compression anyways

Has anyone actually measured for compression with this setup? When I use the c-speed engine builder it spits out 11.75:1 as the compression. That is staying all OEM parts (b18c5).

There was a huge 30 page thread about exactly this in the All Motor forum. I believe the final number was 12.8:1 or something along those lines.

I guess I'll have to go look for that. Finding something with PCT or CTR in the All Motor forum should pose to be a chore. LOL
