READ THIS SHOULD CLEAR UP ALOT
we have learned that the 1jz is a shorter stroke motor that flows better(due to the symetrical design of the cyl head unlike the 2jz, and because of the angle of the ports entering the head) and you don't have a problem getting parts for either motor. the 1jz as it has a longer broader power band and will be more forgiving under high rev throttle modulation, it has a lower deck higth than a 2jz (due to it's shorter stroke) wich gives it a lower center of gravity(balances your vehicle that much better), it is lower dispacement so if tuned correctly can be more fuel efficient than the larger dispacement 2j, toyota has recently anounced the end of the 2j so factory parts will start raising in price but they have no plans of stopping production of the 1j, the 1j was used in many more cars than the 2jz-GTE, so swapping will be cheaper by far and a blown 1j wouldn't be quite as devastating as a blown 2j due to it's availability. piston speed is way down on a 1j so wear and tear won't be as bad, just stay away from the vvti-l 1j if you are looking to mod it

Yes sir, it bolts right on. The 2J Na block and the 2J GTE look identical on the outside. As a matter of fact the majority of people that build 2J blocks utilize the NA block due to the NA block is cheaper and easier to obtain versus a GTE block...
