I know there are stroker kits available, but has anyone ever bored out a 2JZ? It seems that going with a stroker loses you revs, which can be a factor if you're drag racing to avoid having to make another shift before the traps. How large could you go with the bore before weakening it? Would a bored out car be able to rev better that a stroked car?
Thanks

Most of the guys with built motors go .020 over bore....... .040 over is getting pretty close to the limit, considering how thin the wall is between the cylinder and water passages.....

As rwsupra pointed out boring out to 0.020 over stock doesn't buy you much displacement. Boring and stroking are generally very expensives ways to gain horsepower (especially in comparison to forced induction options).
