2JZGE to 2JZGTE Swap Questions
 

I was wondering if anyones ever swapped a manual NA mk4 supra to a 2jzgte? Did it go well? What problems did u run into? Any parts needed that wouldnt be included in a full engine/tranny/ecu/harness package? Any info that i would need will be greatly appreciated, Thanks.

i've never seen it done but from what i've read and watched its a pretty diffcult to do i would say engine/tranny/ecu/harness all of this

Sorry don't understand your question. Are you talking about a transmission swap? Or are you talking about putting an n/a engine and transmission into a TT chassis? Or are you talking about putting a 2jz-gte into an n/a chassis with an n/a transmission? :confused:

i think he's asking if anyone has ever swapped a 2JZ-GTE into a non turbo supra

im talking about putting the engine and tranny from the TT into a n/a, cant be that difficult, the engine and tranny are direct bolt on, the n/a chassis even has holes for intercooler piping...but i wanna know if theres any unexpected wiring issues and stuff like that, i know its not complicated but i wanna know if theres any unexpected things to think about before i do it.

i'd say all of the wiring would needs to be changed the GTE engine runs a host of different sensors that the N/A don't have.

How do you know it's not complicated? I agree with Matt - at a minimum you'll need a whole new primary wiring harness, ecu, ignitor, and resistor pack. While perhaps one might consider this not to be "complicated", it won't be cheap...

+1 on that man i think it would be farly diffcult

how do i know its not complicated?my buddy has a TT and ive noticed that in terms of bolting all the stuff in, everything bolts in exactly the same way and i know i need the harness...but it comes with the swap...anyways no offence but why are you even posting replies if your not someone whos already done this?

What makes you think I haven't done it? I listed exactly what you need, in addition to the v160 and 2jz-gte: harness, ignitor, resistor pack, and ecu. You say you've already got the intercooler covered (aftermarket?). Oh, and you'll also need a different or custom driveshaft unless you also plan to swap your n/a diff with a TT diff. Of course, the exhaust setup is different from the n/a so you'll need an aftermarket (catless) downpipe or an oem downpipe (with cat) to hook up to the oem egcv housing.

Where are you getting the 2jz-gte? If it's from a Japanese engine dealer, it'll likely be from an Aristo, which means the oil pan will need to be changed (you can use the one from your 2jz-ge). It's a LOT of work getting the oil pan completely clean before applying the new gasket material because the upper oil pan is aluminum and there are narrow grooves you have to clean out - of course a steel brush or wire wheel will take aluminum off too, which is why the job is so cumbersome.

However, note that this swap won't produce a full TT Supra. For example, the abs braking system on the n/a is significantly inferior to the tt's.

Lastly, please note that you can't stop folks from posting - especially if the info they have to share is relevant. However, you do have the power to ignore anyone's posts, and wait for someone else to post who has better info for you.

Peace, and best of luck.
