I just installed Civic Type-R pistons in my 2000 ITR. I just want to know what is my current compression ratio. I Heard it may be 11:6.1 or 12:0. Which is correct.

Compression

So you are saying my compression may be around 12:1. Right now I'm running five gallons of 116 octane and five gallons of 93. While running 93 octane I may have to retard my timing a little.

Tuning is going to be key to run that high compression, or run hotter cams.

You can swap the CTR pistons right in the B18C block. To put them into a B16 block, you have to shave the rods a little.

COMPRESSION

Right now I am running the Jun Stage III Cams and spings with three angle stainless steel valves. Im waiting to dyno the car until I break-in my engine. So far the low end torque is bad ass. I can already feel the difference I don't know if its the reprogrammed OBDI P-28 mugen ecu or the compression. I will keep everyone informed on the dyno results................

Just don't get too aggressive at first, that would suck to run a little too hot and detonate...don't want to waste a motor becuase of being careless. Just keep your ignition retarded until you can really get it dynoed.
