I was just wonder if anyone actually messured what compression they got with CTR piston in a GSR motor?

 

any where from 13 or 14:1 put into a B17. ( rare motor) but our neighbor did it..

Pretty sure its close to/around 13:1 due to differences in wrist pin location.

But I am in no way an expert on the subject

 

i have ctr piston in a b17a the pistons sticks out the block. To be safe I ran a cometic head gasket which is equivalent to 2 oem head gasket.

 

so can anyone provide reall info on the USDM b18c1 or the JDM B18c

 

I've heard many differant numbers....b4 my actually built b4 i heard it was suppose to be 12.5...but i highly doult that cause my piston wouldn't have melted the way it did if it was. Now i hear they are 13.1 which is more believable but i have yet to find something to take the time to measure it for sure.

 

try using a compression calculator.

edit: you might want to glance over in the all-motor forum. There are a couple ctr/pct piston threads that might help you out a little.
