Hi all. This is my first post to this forum. I am a Toyota lover from the 4x4 truck part of the spectrum. I am also looking to replace my 1999 Nissan Maxima GLE. The 2nd gen Lexus GS300 is looking pretty good to me. I noticed that the GS 6-cylinder motor is a 2JZ-GE. I believe that it is the same motor that powered the last generation of the Toyota Supra. If this is correct has anybody swapped a 2JZ-GTE (V8 killer ) into a GS ? The Supra Turbo was available with an automatic transmission. Was it the same tranny that the GS uses? Thanks.

As a follow-up to my own post I thought listers might be interested in an article on putting a 2JZ-GTE into an IS300 that appeared on the "Turbo & High-Tech Performance" website.
To further my monologue and enhance my case with visual aids I offer the following.

I don't know what kind of powerplant is contained in this flawless vessel, but, how could it be anything but the perfect candidate for a mild 500hp 2JZ-GTE.

In the 2nd gen GS300 a VVTI version of the 2jzgte has been swaped in many times since in japan they come in the v300 trim with the vvti engine already.In the case of my Gen1 its a easy swap unless you want to go 6spd then you need to modify the trans tunel.
Originally posted by Deep Or you could just turbo the 2JZ GE.
The consensus over in the 22R-TE group (turbo 4 cylinder Toyota pickup trucks from the late eighties) that I belong to is that it's pretty difficult to drop a turbo onto a modern computer controled motor and get everything working right. At minimum I'd want to have a 2JZ GTE donor motor, exhaust, wiring harness, computer and matching transmission. Additionally, you can't really have either great power or reliability without turbo specific pistons. Since I don't really know anything about the internals of these motors I can only guess what other differences there might be.
Of course additional complications could be introduced by trying to swap in a 6 speed manual transmission. For simplicity's sake and city traffic purposes I'd like to go with an automatic transmission, however, I don't know which, if any, will work in the GS300 and hold up to the power of a modified 2JZ GTE.
...the Supra 2JZ-GTE fits in the IS300 engine bay, but owner Brad Smith is quick to point out this is in no way a drop-in. "Nothing bolts in or fits, " says Brad. "The engine mounts are custom, the upper and lower oil pans are custom, the fan assembly, coolant lines, trans mounts, driveshaft, shifter are all custom. Let me reiterate; nothing fits."
Its true that its harder if you're starting from scratch, but there are people putting out 700+ HP on a non-turbo motor with an aftermarket turbo kit. Check Supra Store for more info. Some people say its actually easier to get big numbers (to a point) from the N/A motor because you're not burdened with much of the sensitive electronics and traction control from the turbo motor. If you're looking for a well-balanced ride with about 350hp and similar torque, it might be an option rather than swapping a motor and dropping 10G in the process.
I have seen a lot of na-t projects been done but not all of them have had a great success story to finish it off. One of my friend's dropped a turbo onto his rsx type s and it never saw more than 4 lbs of boost w/o detonation even with stand alone. After it was finished I was a firm believer that turboing an na motor was not the smartest thing to do. On the other had another friend has a turbo IS with a stand alone brain. It ran beautifully until a stereo shop crossed the neg. and pos. terminals and fried his ecu. A couple days ago he told me he got it running again but after a day one of his pistons shot out of the block. In my opinion... nobody should go into a na-t project w/o expecting to have to pay just as much as or more than a motor swap. I always had more trust in factory r&d'd turbo engines blue printed to last more than just a year. But don't get me wrong, I still think you can build a reliable turbo na but not as a cheaper alternative to doing a motor swap.
The 2jzge uses most of the same parts as the GTE including rods and the crank it can hold a good 500whp on the stock internals and a 3mm gasket.The 2jzge is a beast and the GTE is a monster..
I'll admit that I'm not too well informed about this, but, what about the Japanese motor importers? Early 90's Supra 7M-GTE TT motors for about $1000 seem to be pretty easy to get from them. Do they carry 2JZ-GTE motors from the JP domestic market?
