2zr-fe to 2zr-GE

[kmfdeviant530]

So I've been doing lots of research on both motors, the 2zrfe and 2zzge are very similar from the head down, stroke, bore, and block material is about the only difference, but the differences are so mineut that it seems somewhat possible to do a headswap and get a 2zr-Ge. Bore on the 2zz is 1.5mm bigger than the 2zr, and stroke is 3.3mm longer on the 2zr than the, Which is where the problem might arise with piston slap on the head. But again all these can be modded, the head can have the compression chamber expanded for the longer stroke and the 2zr can be bored over to fit the larger pistons. You would then have the better bottom end from the 2zr and the better top end from the 2zz. I would estimate horsepower output, with proper tuning and adjustment, to be about 135 ftlb tq and 185 hp @ approx 6900 rpms, all depending on adjustments of course. Plus you would have the better body style of the new corolla, with the electronic steering, and the rear mounted exhaust manifold with the already practically header manifold.
Anyone else with more extensive knowledge on these motors have any input on this? And I don't want that Internet junkie that thinks he knows everything and thinks it's impossible, or the guy who says that it's a waste, because it wouldn't be. You'd have more hp than previous and current xrs models, more tq than old xrs models and less weight than current xrs models.

Goodluck with that........My advice to you:

1) Engine swap to 2zzge, with electronics mods and lift control...you can easily tune it to 200hp.

2) F.I.

3) Drive your corolla as is and buy a quicker car. (best option)
