Toyota 6 Cyl. Petrol

[TonyP]

I'm assuming that we'll never see the V8 (the one made by Toyota that goes clack-clack-clack, not the one made by GM that pulls up to the unleaded pump) in the U.S. so discussing it is both fun and frustrating at the same time.

The 3UR V8 in 200 Series is a great product as far as Toyota V8s go. If it wasn't a massive engine (DOHC V8s are generally enormous) I would have considered for my project.

Other than the handful of restaurants where the plantation owners hang out and the entrance to the local country club, I seldom see a 200 Series so I had honestly overlooked that V8.

2UZ is a great land cruiser OEM V8. One I would consider if I was going from diesel to Toyota gas V8 in a 70 series.

One of the other projects I am doing, that I don't have time for is squeezing a 2UZ between an 80 series frame, and there is no room extra, so I would say that would be a difficult fit in a 70 that has 1" narrower frame rails.

Not to mention wiring.

Well I am no expert at engine swaps. I just like the 2UZ despite the fact I never owned one. Could have swore I saw a thread or two where one was installed into a 70 series prado or perhaps that was 1UZ.

Love the 2UZ in my tundra. Smooth, decent power. It would be excellent in a 70.
the only knock from me is my mpg in my tundra at bestwas 16.5 mpg. Usually it’s 14ish.

What is the purist position when it comes to a 70 series, Charles?

Premise #1 ... I started this thread simply to satisfy my curiousity about the 6cyl petrol engine that I was seeing in the majority of newer 70 Series in Japan.

What I was not doing was expressing an opinion as to what ENGINE you should put in YOUR Land Cruiser. As for the "purist" comment, I prefer Toyota engines in Toyota vehicles (Preferably a Toyota diesel of some description) and if I wanted a big block Chevy engine I would buy a 1500 Chevy truck. I'm completely happy with my feeble acceleration and moderate speeds on the highway.
I fully appreciate others desire to try different powerplants to make their Land Cruisers unique to them and will read with interest their build threads.

Same engine in the General Market V6 200 series, Previous Gen Tacoma, FJ Cruiser and the 215/285 4Runner. Just a tad bit detuned in the 70 series for the Gulf market. Japanese 2014-2015 70s only had this engine as it was the only engine in 70 lineup which could pass Japanese emission requirements.

Hello Charles,

As discussed above, newer gasoline/petrol 70 Series (from 2010 on if I remember correctly) have the 1GR-FE V6 engine. And yes, it was the only engine able to pass Japan's emission requirements during the brief time the Anniversary Edition was available in that market.

From 1984 to 1991 70 Series Land Cruisers had the 3F engine, developed from the 40 Series' 2F. Unstoppable but thirsty. All of them had the carbureted version, but there are a couple 3F-E conversions out there..

From 1992 to 2009 Toyota supplied the 1FZ-F / 1FZ-FE engine for gasoline models. Up to 1998, 75 Series in Australia had the fuel injected -FE variant; other markets had the carbureted -F. Toyota moved to fuel injection on all 70 Series from 1998 on.

Up to 1999, the MAF sensor was located in the air intake duct and there was a distributor. After that, the intake plenum was redesigned and a smaller MAF sensor was neatly incorporated within it; three coils replaced the distributor. These changes increased power output a little and made the engine more efficient.

US-spec 1FZ engines used on 80 Series Cruisers have the older type intake plenum and the distributor.

The 1FZ engine makes decent power in a 70 Series, but at 12 - 14 MPG (19 - 23 KPG) it may be thirsty when compared to, say, the 1HZ. However, if you avoid start-stop traffic and try to stay around 2000 rpm, mileage improves.

I guess the purist in you would lean to a 1FZ-FE or a 1FZ-F, depending on model year and market.

If your inner purist prefers an older model, then the engine is the 3F.

Be warned, though. These engines make less noise than diesels. You might miss the rumble.

VDJ79?

..

Only thing the 6 is missing is that beautiful rumble

Not so much if you fit a decent zaurst to that 6 ..

Doesn't sound like a 1VD tho

1UZ's fit in Prado LJ78's just fine. The frame is essentially the same as the HD 7x cruisers. Is the 2UZ block that much bigger than a 1UZ block? If not I'd imagine this would work fine. The main difference is the Prado 7x engine bay is a little wider (and shorter) than the HD 7x, so suits 'V' engines better perhaps. The 80 frame is wider I think, and engine bay definitely bigger.

That is interesting. The issue is not the block, but the accessories at the lower portion of the engine. On the right side you have the power steering pump and on the left the A/C and oil filter housing. Having said that the exhaust is very tight on the 80, however, I found the 80 frame narrows together in the middle, while the 70 series seems to widen out. Here is the passenger (right) side of the engine , although, not the final resting spot for the engine, I raised it up some after this pic. I should also point out that the 80 frame does seem to rise up higher, so it may be that the 70 frame will be much lower (thus engine higher) and not in the way of either accessory.

Ah, yes, I could see the accessories being an issue for sure. Here is a picture album of a 1UZ in a Prado. Maybe some of the accessories can swap over between the two motors... 1UZ LJ78 Pictures

looks very similar.
