Unlike its predecessor, which was a twin-turbo inline-six, the 3JZ will be a V8 with two turbochargers. This could like be the engine from the Supra racecar prototype we spotted undergoing testing. We've already heard how great this engine sounds but now we know how powerful it will be.
5| Toyota 2JZ-GTEFeaturing a 3-liter displacement, factory twin turbochargers and shim over bucket direct valve actuation, the 2JZ-GTE was a nearly bulletproof engine from the factory. The stock 2JZ engines can easily eclipse the 800 horsepower mark without breaking a sweat, a testament to the Toyota engineering team.
JZ's are extremely reliable if looked after, but so are almost any other engine.
The 1JZ is the first variant of the Toyota JZ engine to be released, debuting in 1990. It displaces 2.5 liters, with a shorter stroke of 71.5mm, and has a shorter deck height than the 2JZ. The 2JZ, meanwhile, was released in 1991, and has a taller deck height and longer 86mm stroke, meaning it displaces 3.0 liters.
The two companies have had a very close relationship over the years, and a lot of Toyota's best engines were either designed by, built by, or designed in partnership with Yamaha. Even the 1JZ was a partnership between Toyota and Yamaha, and the great 2JZ was Toyota taking Yamaha's work up a step in size.
The IS300 uses the same 2JZ-GE 3.0-liter DOHC 24-valve straight-six that propels the bigger Lexus GS300 sedan, an engine that traces its lineage to the old Toyota Supra.
A 1.5JZ consists of a 1JZ head with a 2JZ short block. This hybrid combination uses a high flowing head mated with a large turbo, all equating to a quick compressor spool. United with the larger 3.0-liter short block, Nakamura-san benefits from low-end torque and great peak power.
Basically so far the pro's of the vvti are that it makes more torque at half the rpm compared to the non vvti, it's a newer engine so less wear and already comes single turbo.
Capable of 2,000 hp. Tightly-packaged, inline configuration.
HKS T04Z is an ideal plug and play setup, but not exactly cheap, but deffo best bet for a no hastle setup. Or go GT40 (ie a T04Z that doesnt look as pretty) and sort the rest yourself. Or go HX40 and sort the rest yourself which would be even cheaper and at least as good TBH, esp if you can do a bit of welding.
Because the 2JZ-GTE technology nearly 30 years out of production. In emissions and reliability form, it is heavy, and inefficient. The 2JZ-GTE was an iron block putting out 320hp. The B58 is an alluminum block putting out 382hp.
In response, BMW has announced it will halt engine production and cancel every one of its engine development programs, and will instead install the Toyota 2JZ across the entirety of its product lineup. Without BMW's support, Toyota is expected to equip the 2020 Supra with the 2JZ going forward.
why do you wanna replace the engine? I've been searching through the internet and posts here about how long the 2JZ-GE engine in our SC300s lasts. The figures seem to start at 200K miles and go up to like 500K miles on the internet.
Both are large, inline six cylinders with similar dimensions and weight. The increased displacement of the 2JZ-GTE yields the same output but it achieves it's peak power at 1,200 rpm lower then the RB26. The 2JZ also nets 31 lb ft torque more at 400 rpm lower then the RB. This hands the advantage to the 2JZ.
Yes, you can run the stock ECU and stock fuel on a single but you really need a fuel controller to tune the most performance out of it and be able to raise the boost to acceptable levels.
Supra's 500Nm torque and the sticky tyres allow it to sprint from standstill to 100km/hr in 4.3 seconds by using the inbuilt launch control, and that is how quick it is. What's more, the new Supra delivers even better performance than the power that it claims.
What does 2JZ-GTE mean? It's the code for the Supra Turbo's engine. “2” stands for the iteration of that block, “JZ” stands for engine's family, “G” means dual over head cams and high performance cylinder head, “T” means turbo, and the “E” means electronic fuel injection.
In my opinion, you will need an absolute minimum of $20,000 to swap it properly. That doesn't include some fab work you may pay for, assuming you can't do it yourself. If you don't know how to swap it and aren't comfortable, DO NOT START!
