Hey guys my mates got a 3.0l 2JZ-GE NA.... He wants to go twin turbo, is that possible? is it just bolt on or are there issues with the manifold, ECU, Fuel pump, etc? Can you do the whole sequential turbo thing like the supra's or is it all a massive head bomb....

There are a lot of people that have done/plan to do a 2JZ-GTE swap. You should ask Joe Radisic as he has a 2JZ-GTE, There are turbo kits on the market specifically for the GE, however fully swapping in a GTE is easier then buying a turbo kit for the GE as the prices will be around the same, and you wouldn't have to worry about ecu and the manifold, etc. because it already comes with the entire engine.

what sort of costs are we looking at here and is it just a straight swap or are there other modifications involved? (if i can source a supra engine maybe?) ps. How do i get in touch with Joe Radisic

Here is his profile, you can pm him there (http://soarercentral.com/cgi-bin/sc-forum/board-profile.cgi?action=view_profile&profile=joe-users) It is strongly recommended that you upgrade your brakes as you would need the extra stopping power. If you're going to do the swap in yourself, it'll probably save you at least a thousand in labor or so, but thats only if someone doesn't hook you up with a shop. Here in the states, engines go for around $4,000-6,000, and some on eBay go for as low as $1,200 but are damaged in someway, but are usually repairable. 1JZ-GTE is also an option and usually are less expensive than the 2JZ

Hey I am aware of a couple of important internal differences between the 2jzgte and 2jzge that may sway you towards swapping complete engine or rebuilding and planting a turbo on the 2jzge. 1. the gte has oil squirters to squirt the underside of the piston for extra piston cooling. 2. more importantly the gte runs a 8.5/1 compared to the ge 10/1 comp ratio add a turbo or 2 to that and you get excessive heat and wear on the engine and pistons especially without the oil squirters.
I'm sure there would be some difference on the intake side also so you could be up for a custom intake?????
Dropping in a 2jzgte isn't too hard, I didn't use 2j turbos so don't know what is involved with that side. The 2jzgte comes with a few variations depending on model they came out of like sump, water pump, hydraulic fan and a few small hoses are different but its easy to deal with when you get to them, you can use parts from existing engine but that may make it harder to sell complete.

thanks so much guys, so you generally figure the 2JZGTE is a much better engine with less mucking about? i just figured that if i could source the parts cheaply it might be a better option if there wasnt too many hassles. However im probably looking to get about 300Kws or so, and want to do a great deal of weight reduction, which may help strain on the engine.

Weight reduction will more so help with strain on trans and diff then engine. And unless your doing alot yourself labour adds up and is not cheap. Goodluck

Yep ill do it myself, just a matter of how professional i can convince myself i am.... Personally id want to get a 98-99 model before i start spending life savings on the thing. I think me and my mates are the only cruisers nowadays in South Australia, thanks so much to you guys for the help, im suprised that there are still people that provide information and ideas for free Hey Joe, sorry i just noticed you also have the V35, i also have the hv35 gt300, is yours a 2 door? How does the handling compare to a 350z? (perhaps i shouldnt be asking at all since its a soarer forum....)

I've read somewhere that you can lower the compression of the NA engine by putting in a thicker gaskets or something... sounds too dodgy to me though.
I was looking at it out of interest couple of months ago as my IS got a 2J NA as well, and basically it works out to be cheaper and less hassles just dropping in a GTE... also if you were to get a supra half cut, you'd probably also get the six speed manual transmission with it, now that would be an awesome bonus!

Its a sedan, handling is very good no need to lower it, I have not driven a 350z to compare. It has the 3.5L 8spd semi auto with paddle shift no need to change a thing on this one just drive and service, very happy with it.

going about a 2jz gte drop in shouldn't be that hard, but what about other stuff, like bigger brakes? diffs? drive shaft?
iam not planning to do it.. just thought others would like some answers
i guess any real upgrade to the GE would be the 1.5jz, unfortunately from my research it can be costly in regards to the custom gasket from the US of A and other stuff

I know people in America swap there sc300 with a 1jz because it never came out there and importing one would mean the steering wheel would be on the wrong side. But in Aust there is absolutely no point swapping a 2jz-ge with a 1jz-gte. Whole lot of work just to get a car you could buy for almost the same price and selling your N/A 2j.
Heard that neil is working on a supercharged kit for the N/A 2jz which might be good if you just want a bit more grunt while keeping the 3 ltr.

Scott : Really? Who/Where did you hear this from? That is great news. I am really looking for a decent increase in low end torque for the 3L as the car really does need it. Being such a heavy car it is fairly slow off the line and this gets worse with the aircon on!
People say you won't get the same power vs going NA-T but street driveability is what I am after not a highway runner.
I'm sure you could piece yourself a high response turbo setup with twin scroll manifolds and new fancy turbos but the price then suddenly exponentially skyrockets vs off the shelf kits (<5k from the US stuff).
SC installation also seems easier than NA-T (not that i have any exp. just reading alot of DIYs)

Neil from Rush Imports. He is on this forum I believe. He is the one with the supercharged manual (r154) V8. I myself have got a supercharged v8 Soarer and I feel your pain as I think only now has it got about the right power for its weight.
Still the Soarers are lovely cars and the 2jz is no exception. If Neil gets this kit off the ground at a reasonable price I'm sure heaps of people would be more then happy with the response and power unless they want big power in which case the 1jz-gte should have been bought in the first place.
Let me know how you go.

I went the na/t setup, for the fact i wanted a big single turbo setup and didnt see the point spending the money on a 2jzgte conversion then having to spend extra for a single turbo conversion.
