LS vtec compression
I want to know exactlly what compression I am running I have a B18 block with B18b rods and USDM ITR pistons and I am running a B16 1st gen head. Also the head is milled 40 thousands or so. Anyone have any Ideas, I was told it would be over 12:1 don't think that is true....

Re: LS vtec compression (rainforest)
I know for a fact the set up ranges from 11.1:1-11.2:1
I know cause this is my setup. pr3's put approx. 11.4:1 and usdm itr domes are less.
hope it helps evo.

Re: LS vtec compression (WAFFLES)
yeah but compression is different depending on rods pistons block crank and the head. Plus my head is milled 40 thousands, there is no way that USDM ITR pistons with a b16 head milled 40 thou is 11.1:1

Re: LS vtec compression (EVOCELICA)
Yeah, 11.2 ish on the jdm itr pistons with no milling of the head(b16a), usdm itrs are 10.9 or so. But with that much milling, it should go well above 11.5, I agree it is around the 12.1 comp. ratio.
