11.5 or 11.8:1 depending on whether you use a p30/pr3 or p72 head

just did p30 (Nippon pistons from eBay) pistons in a b18c1 block with a p72 head, we clay-ed it and the castings arrows on the pistons hit the flat spots in the combustion chambers enuf to tap with out stopping the motor, so we hat to grind a little off, we were running jun stage 3 race cams and after claying again had about 30 thousands clearances p2v,(at about 10,000 rpm there is about 40 thousands stretch in a rod, so we used a little thicker head gasket and had no problems car runs great,
p30 pistons stock gsr block and rods balanced , ported head SS valves, supertec springs and retainers, Jun stage 3 cams,$80 eBay header, old school plastic power chamber intake, s2pro2 intake Mani, stock Tb DC 2 1/4 exhaust with 440cc(over kill but got them cheep)injectors tuned on hondata made 203whp and 142wtq at 9700rpms, with a better exhaust, TB and header hopefully we can make 220wheel, not to bad for a budget build and k swaps ain't got **** on it, now only if we can get a tranny to hold 5000 miles on the motor and as of tonight 2nd tranny they dont like those high rpm shifts lol
