it is a good bit higher than 12:1 with a gsr head. I'd say close to 12.3-4:1 due to the different comp[ression height compared to other b series piston. Basically running ctr's has the same effect as lopping 30 thousands off the block deck.

You will be fine as long as your car has the proper fuel tuning to manage such a high compression ratio.

I highly recommend hondata or a fuel controller & some dyno time to tune your fuel.

I have built an ls/vtec w/ a simular c/r on a kenji p28 w/ 16 btdc timing & it runs fine, it had not been tuned yet & it has over 3k on it.
