I was watching a YT video of racing shop do a full rebuild on the 2JZ and started to wonder if anybody's done this transplant or why you wouldn't. I'd much rather have a Toyota inline six than a Chevy if I went to that time and expense.

2JZ-GTE has been put into some of the 70 series long wheel base (LJ78 for example). Because it's a small displacement motor, it relies on boost to make power. In a heavy Landcruiser, it's in boost all the time, which means it consumes a lot of fuel. Even in the LJ78, it only achieves around 25l/100km or 10us mpg from what I've read. Would be worse in the heavier 80 series. It's also a high revving sports car style motor. With a Landcruiser, you usually want a motor with a lower rpm torque curve. In addition, it's becoming an older engine now, and is quite complicated for what it is (sequential turbo system etc.).
Turboing the 1FZFE would probably be a better option...
As above I wouldn't want to lose the displacement.. 4.5 to 3.0.. refresh the 1fz and slap on your favorite flavor of turbo and you'll make plenty of power. These heavy trucks need low end torque vs high rpm hp, yes the jz makes plenty of torque for light cars, it's just not where we need it for these rigs imo. My jz in my SC300 made over 550 ftlbs at mediumish boost, mid 20's, but that was in the area that the 1fz is almost redline at 4-6,500rpm, you don't need an 8k rpm 1fz if you are rock crawling and moving slow, maybe if you were sand dragging, but that's a different ball game. Just my .02 and.. there is a thread of a guy who swapped his 80 with a jz.. it's a recent thread, within the last 2 or 3 months, I feel like he was also doing a manual r154 or some r-series transmission swap along with the jz
Right here buddy:

My personal two cents: the 1fz is better suited to a truck application because of the increased displacement. Either motor can be tuned to eleventy-hundred horsepower in the hands of a capable tuner. They are actually pretty similar in construction--1fz is the plus-sized brother of the 2jz.

Goal started out as building a supra kart mk3 but it was a turd on wheels, but it had a motor and trans that were in decent condition. After selling the Supra and it’s trans it was decided that the 2j should go in a land cruiser 80 after much thought about putting it in a 4runner first gen. The...

How? I’ve never seen anything suggesting there’s tuning options for our motors. Is the fz an iron block close deck design?
There are supra drag guys who have removed the 2jz in favor of our 1fz motors. A built 1fz with tons of boost is a monster. 2jz is awesome but pretty backwards in an 80. "So I have this heavy truck, I'd like to heavily reduce the engine size and move the effective RPM up by 2-3000" 
The 1fz isjust as capable as any jz at making stupid power if not more due to the extra displacement. there is a plethora of aftermarket internals, rods, pistons, cams and stroker cranks, even billet front facing intake manifolds and turbo manifolds. As far as tuning while there aren't many plug n play ECU's wiring up any of the available standalone is a cake walk. Don't get too discouraged by the lack of performance boosts you aren't finding on mud.. its just not what the croud here really desires.. no disrespect at all to anyone here. People here desire suspension performance vs engine imo. But yes literally you can do anything a jz can do and more except have VVTI.

What is it exactly you are trying to do anyway? And to your question above, yes the 1fz is a closed deck iron block design just like the 2jz
Dang why was I not mentioned
Build thread is F2j hades

I linked your thread up there ^^^, fella 
I mentioned you but i didn't know who you were, just that i saw your build. nice project, it has an R series swap too correct? how does it drive? I know how boosted JZ's operate but like i was saying i figured the the high revving aspect isn't best suited to the LC speed/engine operating range, don't get me wrong i love what JZ's can do but i figure why not just keep the added displacement +boost??? got any vids of your rig in action?

Have dual cases so off road is easy
Yes have an r series bout to rebuild it
When I got my truck it was just a roller and had a 2j in storage so figured why not.
I will say with the 2j or a 1uz lots of options and lighter than the stock driveline not to mention cheaper abs easier to find.
And yeah check out videos on my insta 1348_racing

Thank you. I only just found out that its basically the big brother engine to the 1JZ. I had no clue there's stroker kits and and cams out there either. Exciting stuff.
Make a lot more power, I have no interest in a swap. Anybody know what engine management system the guys in the desert run? Sounds like they're the only one running the stroker kits.

Haltech do a plug and play for an FZJ80, costs about 2.5k AUD. Turbo manifolds aren't hard to come by or get a kit from Wits-End. Stock head bolts and gasket in good condition is apparently good to about 20 pounds of boost.
Even at 6 or 7 pounds of boost a turbo 1FZ is an animal, silky smooth and plenty of torque. I miss mine pretty well every time I see an 80.
Yes, 2J is a good engine but the FZ is its big brother, already is in the cruiser and has power delivery better suited to a big heavy truck.
Edit: IMHO skip the stroker kits, from what I've seen they're not the quality of the OE Toyota parts and at 4.5 litres she's got enough displacement anyway. Some of the drag builds are de-stroked so I wouldn't waste your money with a stroker kit

No matter what engine is in there your enemy is resistance because the only thing that breaks things is resistance
as for engine management I am running ecumaster and it has been great.
