351 windsor into the gz20...yeah baby!

But on a serious note, keep the 1ggte, then throw in a 1uzfe or something when money permits

Its basically a 2JZGTE. The differences in the heads between the 2JZ and the 1JZ aren't going to make a huge difference, and whether its beneficial is a moot point. Because you're using a 2JZGTE bottom end, the bore and stroke are the same as a 2JZ, and if there is any difference in capacity it'd be the minute differences in the combustion chamber. The only major benefit of a 1.5JZ is making a 1JZ bigger

the way i saw it was basically a stroker.. making it 3 litres instead of 2.5.. or was i wrong?
and the only way its worth doing is if the 2jz bottom end was sourced really cheap

Just trying to say what everyone else has now said - a 1.5JZ revs exactly as hard as a 2JZ as the bottom end is the same (technically it'll rev a bit less than a normal 1jz as the 1jz is under square and the 2jz is perfectly square). The reason to build a 1.5JZ is if you have a 1jz and blow the bottom end you can buy a 2jz bottom end for the same price. Luckily the 1jz head bolts onto it, allowing you to keep any turbo upgrades you may have spent on the 1jz (manifolds etc will not bolt onto a 2jz head). From all reports the 1jz head is not inherently better than a 2jz head.

Hey, it was Friday afternoon when I posted that! I thought it was funny
