Yea I definately plan on researching it more before I get in over my head. The thing with getting the 1jz swap installed and running properly and then buying a 2jz engine, wouldnt that be more expensive considering I would have to by the 1jz setup with engine, rather than just getting the 2jz engine and all parts necessary?
Honestly, a 1JZ and 2JZ Mk3 are very similar. Engines are interchangeable and the electronics can be too. I wouldn't say a 2JZ swap is "harder." It's just different and not as 100% straightforward as buying a 1JZ half cut. If you know what you're doing/buying, a 2JZ swap can be just as easy as a 1JZ swap. IF you know what you're doing.
I mentioned 1JZ because it's alot easier to buy a 1JZ half cut or engine set, which is basically the entire engine bay removed from the half cut, and put together a running car in as short a time as a weekend. 1JZ MK3 is a pretty straight forward swap if you buy a clip or engine set. You can't just buy a 2JZ MK3 half cut. You have to know what you're doing a little more. You would be in the same boat if you bought a 1JZ engine with just the harness and ECU. You'd be piecing together a ton of parts to finish it into a running car.
Alot of guys with 2JZs are able to do so because they know exactly what steps to take and what parts to buy. Usually because of previous experience with a JZ swapped MK3. Most of them started with a 1JZ swap at some point, or had friends go through it. For some, they can buy just a 2JZ long block with harness, ECU, and assorted accesories, know what they're doing and put together a running car. Some guys would be totally lost if they tried to put together a 2JZ or 1JZ swap from scratch.
Some guys had running 1J cars and just swapped out the long block for 2J.
There's alot of ways to put together a JZ MK3. The most striaghtforward is a bare bones half cut 1JZ swap. Some are done with an engine set. Some are done from only an engine and some electronics. Some started with Soarer engine or Aristo engine. Some started with Chaser engine. Some run the hydro fan, some run clutch fan, some run E-fan. Some run 1J harness and 1J ECU. Some run 2J harness and 2J ECU. Some run modified 7M harness. Some use Soarer ECU and harness. Some use Aristo harness, ECU. Some use standalone, custom ignition setup, etc. So on and so forth.
There's lot of different ways to do it. 1JZ and 2JZ came in a lot of cars. There's alot of different parts out there for JZ engines and if you don't know what you're buying you can end up in a world of hurt. There's alot of stories of guys buying engines or harnesses they thought were from a Supra but were actually from something else. Then they're stuck trying to retrofit a JZ swap or find the correct Supra parts instead.
sorry for rambling...
