2jzgte swap into a 350z?? Wha?

[gabegtz84]

I have a buddy whose thinking of putting a supra engine into his Z. Has anybody ever heard or done this swap. i'd love some feedback.

[samej82]

yep... It's been done before... IMO keep the VQ

[evildky]

search, there is a guy here that did it for a customer with more dollars than sence

if you spent an equal amount of money on the VQ you'd have as much power

[S3t0_S13]

tell ur friend to gimme the VQ

[gabegtz84]

Did a little more research and it seems that if you know a guy who works on 2jz's it might be a good bet for a freeway monster, the engine is soooo friggin built stock, i'm kinda thinking he should go for it

[evildky]

my problem with the 2jz swap is that lets say you want a 1000 hp car, with the VQ, you have to build a sleaved block with oversized headstuds, custom cams, turbo kit, injecotors, managment, etc, with the 2jz, you have to fab mounts, for the engine and trans, fab a driveshaft, custom wiring harness, and then you still gotta do injector,s turbo, managment, signgle turbo conversions etc, the only thing you save is building the bottome end and I'd rather build the bottom end than deal with the hassle of fabing mounts harness shafts etc

Other than the harness, and custom fab mounts the 2JZ will be a better motor in the long run.

The single turbo conversion is easy, and cheap. You can slap on a 76mm turbo for under 3k. That is MUCH cheaper than a VEQ turbo kit for the same size turbo. You are building the fuel system out no matter which route you go, so there is really no cost diffrences there. The fuel rail for the 2JZ is under $200, 1200CC injectors are $80 each from RC. etc. etc.

What about the Z's transmission? Rear end? Half-shafts? rear hubs? Can they take 1000rwhp for any length of time if at all?

My 2JZGTE has over 143,000 miles on it, it is bone stock, and has make over 600+ rwhp for 100,000 of those miles. For the past two years it has made well over 700rwhp, and is currently over 900rwhp. I did a leakdown a few months ago, and it was still under 3% per cyclinder.

There are VERY few engines that can do what 2JZ can do, and the VEQ is not one of them. There is no way you are going to make any real power with any amount of reliability out of the VEQ without spending almost as much money building the engine as you did on the car in the first place; And to do so is just foolish IMHO.

If you want to make real power, and not spend outragous amounts of money, sell the Z and buy a car that was designed to make stupid amounts of power.

Think I am crazy? Call any good performance shop and ask them for a qoute to take a bone stock Z 6spd to 900+ rwhp, and still get 100K+ miles between rebuilds...

Nobody can argue that the 2JZ is one of the strongest engines ever made, there's even accounts of people taking the 2JZGE to over 900whp on the stock internals on a block with over 220k miles. personally I'd love to see the swap done, but then it wouldn't really be a Nissan anymore.

[quietkilla6]

just think about the looks your going to get when you go to a mechanic whith a problem and tell him ur nissan is a toyota than think about all the guess work that goes into working on this project and fixing a project like this... its not hard to put it in and to get it running but it is hard to work on when you go out racing and blow something up

[Kouks]

My friend has this done, XAT Racing in Tampa FL did it. 700whp stock block 2jz 2003 350z. Silver Black Wheels. Only one I know about in the US. See if I can find some pictures.........

Its not for everybody surely, he spent ALOT of money doing this. To be different was surely one reason. The other reason, no lie, is because he wants to build a 1400whp highway car. Show me a VQ that would handle that. 2jzs are proven, kinda like SBC to hot rodders.

People mess with cars because they like a certain car and want to make it to their tastes, not everything in building a car has to make sense.

In fact, if that was true very few people would mod a car anyways, because you almost never get the money you put in to it out...

Just my two cents.

Yes i am Currently doing a motor swap into my 350z with a 1jz vvti. Our company, tech 2, specializes in motor swaps... my 1jz has a front sump oil pan which in turn made making the kit for the swap relatively easy.. with some fabricating to the crossmember the motor fits in great. We also specialize in doing wiring harnesses for both the 1j and 2 j which has seemed to be a problem for a lot of people looking to do that particular swap.
