Well i found a 2JZ engine but not sure if its turbo or not im guessing no but anyway its a 2jz which is just cool. so guess how much they want for it $300 i was like Damn whats wrong with it so i need to get the number and call. because im looking into getting a MKIII Supra and a 2JZ swap would be fun

I understood that the 2JZ was a turbo motor and the 1GZ was its N/A counterpart. $300...it's a good deal but are you sure your getting some worth it? It just seems really inexpensive for such an expensive motor.

Good luck.

The 2JZ can come either turbo or naturally aspirated (2JZ-GTE or 2JZ-GE). There is no such thing as a 1GZ. There's a 1JZ-GE and 1JZ-GTE as well though.

1 and 2 are versions of the engine.
JZ is the engine code.
G is the type of head. (performance in this case, there's also the F heads which are more suited for daily driving)
T indicates the engine is turbo
E means the engine is fuel injected.

Yeah, I got all the coding. The "G" was a typo. I'm not sure where I heard that one was the turbo and the other was N/A. I should have clued in by the codes...Thanks for the clarification.

Just a quick correction, there is such a thing as a 1GZ, and it's the super-super-rare toyota motor. Five liters, V12, 4 cams, 48 valves, BEAMS, two throttle bodies,VVT-i. Came in the Toyota Century.

Well then, it was a typo but that is one damn cool motor.

This is the same motor that is used in the current TopSecret 1,000hp Toyota Supra. By the way the 1,000hp mark is what has been set as a goal by the builder, and not a concrete number as of yet.
The Toyota Century is a Super Luxury vehicle that in stock form puts out (?285bhp?)

Wow, a Toyota 5.0 V12? Thats god-like. Too bad theres not a manual. Nice links Hiko

285hp from 12cyl? Seems a little ridiculous to me. Should be more like 285x2.

The 12 was rumored to be the powerplant of the next gen Supra.

Neither the 2jzge or gte are direct drop-in swaps for the MKIII anyway, that's why so many that don't want the 7M get the 1jz because the 1J was actually in MKIII's, but only in Japan, so it's pretty much a direct swap. The 2j requires a little modification. It's not beyond the realm of possibility, it's jus the 1j is cheaper/easier to do.

However, if I personally ever swap the 7M out, it would probably be a 2J that went in, not a 1J. I'm a bit odd in that I actually like the 7M, and my shortblock is young, so it'd probably be a long while before I swapped at all, but if I did go to the trouble of a swap, I like the 2J enough to do the extra work for it.

285hp 12cyl = super smoothness.

More cylinders at a given displacement is always better since it spreads the load of the power (there's a specific term for this, but I forget it). Sumthin like that.

It's a balance issue, but yeah, more cylinders isn't necessarily just for more power. Remember TNO, there are sub 3.0L V6s out there that make the same or less power than a 2zzge. Heck, the 1mz stock for stock makes about the same horsepower as a 2zzge, but the 1mz is a much smoother platform

/maybe/. But, if I were going all out like that I'd be tempted to just have ChrisK make a monster out of the head and build a new manifold. What I will probably actually do at some point is have him build me an intake manifold for the 7m with front feed TB.

i have a friend that has an 89 supra turbo with only intake, exaust, but he had ta port and polish on the head and he has coms in it, and this thing runs like a raped ape, and thats at stck boost, if he turns it up to 12lbs and on a cold night with race fuel 14 lbs it climbs fasssssssssssssst...160mph is easy at that point

What cams? I'm assuming regrinds, hadn't found anyone that made cams for it. What are coms?

I'll cry if there are cams out there, I looked after my exhaust cam snapped and finally bought a new factory one since all I could find were regrinds (which require a good core anyway).

hks 264's


also there are hks 274's


n/a 7m cams work as an upgrade


other 2 u can get from hks or titan

Bleh, HKS are discontinued AFAIK. Some folk say the NA cams are an upgrade, but I'm very dubious about that and I'm not the only one. I bet Titan's are regrinds but I'll check.

been in a car before and after, there was a noticeable differnce

the 7m with the hks 264s pulls like a mad man....and i rode/drove before hand, and after.....i forgot to mention it has a 62-1 turbo


the n/a swaped cams were a decent upgrade, the guy got em out of a 50k 7m though, rode in a car with em before and after but it had some other stuff done beforehand also

Oh I don't doubt the HKS are an upgrade, you just can't get them anymore unless you find someone getting rid of them. I still doubt the NA cams are better, and if they are, not enough to be worth it. Only way to prove that is a dyno before and after with no change but the cams.
