Default Compression with CTR pistons?
One a stock B18C5 motor, oem headgasket with stand bore CTR pistons, anyone know what the compression is?

I heard C-Speed Racing website calculation is all wrong so I'm not relying from them.

approx. 12:1, according to sgt the ctr piston sits .030 higher than any other b series pistons when comparing piston to deck height....If I remember correctly sgt approximates around 12:3:1....hope this helps...

It is approximately 12:1 with a stock head gasket and that is if your head has not been milled down.

Were SGT's measurements taken with the PR3 head or the P72 head? And it was a P72 block, with the 1.8 VTEC crank I'm assuming, right?
