[SIZE=2]2g BOV sucks. 1G head, with a 2G manifold, 1g bov(crushed) is the way to go and a stock 1g-4g63t is 7.8:1
stock 2g-4g63t is 8.5:1,
the 4G63 NA is 9:1, with cast pistons, and smaller ring lands, no oil squirters, MAF sensor, and knock sensors are also different. is it a NT trans or turbo, because the FD is different.
