yes, i am intentionally dragging this old post out because it contains info. i found in my search. i plan to put a fresh vg into my se in the near future. i read recently that if you bore out a vg30e to fit the vg33 pistons that the wall thickness was the same as a stock vg33e. this post contradicts that. i want to overbore by 0.040 with higher compression but if the vg33 pistons fit then why not? my budget is not an issue. i do not intend to build a high strung race motor, just want to squeak out a little more power that can run on pump gas. turbo is not an option on my se, as i want to keep it close to stock. i have other s12s that might wind up with boost. so does anyone have other references or even better, personal experience with the vg33 pistons?
