4gze mods. ? 4 all
hey guys I recently purchased a 4gze with about 90k miles on it and is the process of a complete tear down and rebuild. My question(s) is what would be the most effective way to raise the compression of the motor? shaving the block and head or putting in aftermarket forged pistons for a 4age(na) and if I did raise the compression will the stock head bolts hold? So far I've had the head and intake manifold ported and polished, 3 angle valve job, had the valves polished and honed the blocked, I ordered a oversized HKS crank pulley to increase boost, TRD valve springs and retainers, TRD fuel regulator, and 3rd gen. supra fuel pump. I wanna do about 250hp and I figureed if I raised the compression from 8.5>1 to 9>1 that should put me right where I wanna be. I figure forged pistons for a NA 4age would work best since there CR is higher than the gze but would like a second opinion. Thanx
