GTE Swap vs NA-T rebuild: What makes more sen$e?

Due to engine issues (ultra low compression - 50lbs, oil leaks, etc etc), I finally gave up and am planning on swapping this summer.

For reference, I have a '98 2JZ-GE VVT-i (auto tranny)

I was fortunate enough to meet someone who has done 2JZ swaps in my area, and has good tuning experience as well.

I am presented with 3 options; I'm trying to figure out what makes more sense in terms of difficulty AND financially. I basically want the best bang for the buck:


1) Buy a low priced JDM 2JZ-GTE (~$1500-$1900) and do a direct swap. I know I need a harness and some other things. Also I was told I cannot use a 3" pipe because of the WG on those?

2) Keep the block and rebuild it and upgrade head + other parts to transform it in a real USDM GTE.

3) Keep the block and rebuild it and go NA-T (Also quick question: which electronics are compatible with VVT-i for NA-T again? AEM?)


I'm willing to spend between roughly $4k to $8k on parts and labour, and wish to end up between around 400hp to 600hp, I don't need more (not right now anyway). I want something reliable, so NA-T could be taken out, unless a full GTE rebuild is too expensive.

You guys' expertise and input will be greatly appreciated, and directly responsible for the revival of a Supra in desperate need :(


Thanks!!

im no expert in that field but ive seen a couple complete NA (2jzge) motors go for like 400-600 bucks. thats a pretty cheap fix if your just trying to get your car back on the road

Yeah that was another option I was looking at, but I'd still have to pull out this engine out and cost a few grands, so I'm taking this opportunity to go turbo. The car still runs, hey what'd you expect, it's a Toyota after all! ;)

You could also get the motor from Tiger for $1350. You don't need the harness because the wiring is almost identical. IIRC there are two sensors that are swapped and you can easily splice the wiring to the correction location.

I have a whole bunch of links to wiring diagrams, etc., from my 2JZGTE / S13 swap.

I see you are in Canada though,so if you find a complete GTE swap out there,go see it in person,make them compression test,leak down test it in front of u,then u would know for a fact you are getting a good,clean and healthy motor
i have been burned a few times by jdm suppliers in Canada,so now i am very cautious about them

Let me tell you how the XS turbo I had lasted me less than 2000 miles. LOL

I was waiting for it to blow up though. Its was a matter of time. I just put it on to drive the car. Now its just a matter of time till I get my adapter for my new turbo in and put that on along with my new wastegate! CANT WAIT!! Haha

GTE with single turbo off the classified section..

Yeah it's starting to look like that TonyN. I'm curious about a rough estimate on the parts list. I'm going to see the guy this week to see what I need... I'm assuming a new head, pistons, rods, cams, injector, fuel system, ecu, electronics, and the whole turbo kit ..... damn it's gonna cost quite a bit though! AAAAAaaaaahh...

It is cheaper, and you will have better results if you just go GTE swap. Are you looking to convert to a 6spd at the same time?

I am guessing that a 6spd & GTE conversion will cost you roughly 13-15k total if you did both at the same time; about 5-6k for the GTE swap.

thats just on parts though i think he was looking to spend 8k in total. you have to factor in the labor which will be a lot of money so to be honest he probably wont' be able to get the gte swap anyway.

with that amount of money you can go NA-T, built transmission and TT bottom and be good for 450whp.
and you can do most of the work yourself.
