It's amazing to think that variants of this engine was in service for close to 17 years. In Japan, it was used in Mark IIs until they updated the car to the Mark X in 2007.
The 2.5L 1JZ even served to be part of the Toyota's 5.0L V-12 (the 1GZ & 2GZ). Toyota combined two JZs at the crank to make the V-12 and stuck it in its Century Limousine.
The V-12 was famously used in Top Secret's 222mph 1000hp+ Supra.
The I6 is a victim of a world obsessed with FWD packaging. As the volume car platforms progress inexorably towards complete FWD domination, so goes the I6 blocks. Even the mighty GTR has to make do with a bent-6. Pretty soon the BMW I6 will be the lone soldier battling on, bravely resisting the need to turn engines around and destroy driving dynamics and pure, inline-6 smoothness. Next time you see a 130i burbling past on the street, raise a little salute for the last small car with a big 'ol straight six pointing forwards, just the way the car gods intended. #i6engine
Metal head gasket and a bunch of bolt ons and your JZ will reliably deliver 600+ at the rears with a good tune.
I had a G series as well, the 1GGTE. Put a whole in the radiator and didn't realise until the engine had burnt all the oil overheating. BUT no gasket gone or anything like what happened with my Nissan RB engine, just a plug popped out of the manifold. Bit of tar and a new plug and away we went.
They say that hooked up to an engine dino the G series will take 50,000 rpm before shooting pistons out. For how long who knows... #i6engine
@Mobius: Camry V6 engines are borderline supercar engines. el oh el.
Lotus has great sense of humor imo they could have always get a partnership for Audi/BMW crate engines, but instead they went with Toyota years ago for the cup cars. #i6engine
I was literally blown off the interstate yesterday by a Lexus IS300 Wagon, twin turbo'd. I know that the best sleeper cars are the uber-wagons and a potential 800 hp has GOT to be sweetest family hauler imaginable. #i6engine
The 2JZ is, I believe, the strongest factory engine ever built (aside from limited production stuff). 850-900 hp on the stock crank.
I would personally kill for a 600 hp Chaser. Nothing more awesome than seeing two of the big saloons at 150 mph on the Shuto Expressway outside of Tokyo. #i6engine
@snapoversteer 'bout to get told: Shouldn't comment when I'm still leftover drunk. I forget where to find it, but some guy years back kept pumping nitrous into a 2jz on an engine dyno. I believe the stock internals blew at 700-800 hp. Guys running huge boost are still running the stock crank reliably (obviously taken with a grain of salt at those levels) at up to 900 hp or so. #i6engine
@Sheed's Bald Spot: My boss has 2 of them, and the hotter one makes about 600hp with no internal upgrades. It's an amazing engine, but my point is that it's hardly a Toyota factory engine. All the 2jz's, IIRC, were blueprinted at a race shop in Germany. In fact, I think most of the overboost horror stories you hear are from people putting FI on the NA engine. #i6engine
Just picked up a '49 Plymouth with this engine. $500 I paid for the whole car. The oil looked fresh, I rigged up a battery to it and poured a little gas down the carburetor. That little engine just took off- what a sweet sounding I6. I believe by '49 it was rated around 97 horsepower or so, but 200 lb-ft of torque or thereabouts at something like 17 RPM.
The oil filter was _optional_ on this engine- that's it in the above pictures off to the right, the speckled white and black jug with the black lid, with the band clamp around it.
When it comes to old engines like these, the level of simplicity* blows my mind.
The nuts and bolts are large, and placed where you can get to them. Everything's got lots of room around it and there's lots of extra metal.
This was before a host of modern concerns forced the optimization of mass and volume that leads to oddly placed bolts that you strip as you run them into and aluminum head.
So, fifty years later, what were the final performance numbers? Still 68 horsepower?
It's not often that I don't know anything about an engine on EOTD, but you've stumped me here. I've never seen one, touched one, worked on one or tasted one. Mostly because, well, let's face it I'm not a huge Mopar fan, after they killed my beloved Rambler.
@Deartháir II: The Return: You take that back. MoPar never went near AMC until the late-mid 80s and Rambler was a dead duck way before then.
Rambler was actually killed in 1983 by Vehiculos Automotores Mexicanos (VAM) in Mexico--that's where the last Rambler rolled out.
Of course if you mean, MoPar killed Rambler out on the streets, well, yeah. Killed it a quarter-mile at a time.
This engine had to walk to school uphill, both ways, in seven feet of snow (or, in its appearance in the original Chrysler Metric, 2.1 metres). And it lived long enough to tell you about it.

In its more famous applications, the engine makes one JZ. #i6engine

Ih, I always dreamed of a Toyota Chaser with the Twin Turbo'd JZ. Just so cool and Q-shippy, especially in white. #i6engine
