Hey Guys, I know there are a million posts to go na-tt but I always get incomplete ansers. I have searched but I would like exact answers because I am going to be starting my swap in a month.

I would like to know if anyone has gone 98 NA-TT. I need to know exactly every single part I will need. I am going from a stock 98 NA (vvt-i) and I want to swap in a stock 2jz-gte. (Yes I want to keep stock twins) I want to create a LIST of every part I need. Please don't just tell me (motor/trans and ECU/Harness). I would like to know all misc. parts as well. I heard I will need a driveshaft. Things like that. Any help would be greatly appreciated.

hey spot, i've noticed you've posted numerous times in an attempt to try to find some way of making your 98na fast without screwing evrything up. It seems like everyone that's 98na just doesn't want to risk what no one else has done so they do wild things like superchargint their na. I am personally a 98na and i've got my turbo kit on the way, in a few weeks i'll post everything and you can see my progress. So far as the 98na-tt the wiring is completely different. I know you've probably seen Champazn on supraforums and he is currently preforming the na-tt swap as we speak. The was also a guy in austin that preformed the swaps but i believe he is banned now.

a bunch of those are only needed if you get an aristo/jdm engine and want it updated to USDM spec, if you do you will also need to swap and drill your n/a oil pan for the oil return line. you will also need the flange for the TT rear diff and the rubber coupler(larger than the n/a one)to install the driveshaft if you keep the n/a diff. Also if you use an aristo tranny you will need the flange for it to bolt it to the auto TT driveshaft. You will need the upper rad hose and maybe the hoses for the heater core on the back of the motor. You may also need the TT fan. You need a TT throttle cable too. And stuff like the boost guage, downpipe, intercooler/pipes, and the TT tachometer that you probably know about. Jdm spec motors also require a restrictor plate in the 3" down pipe to prevent overboosting. That lists most the issues I've had in my swap

Not really need a lot of money, try to look for used parts..
doing swap is fun, you can learn about your car.
you can buy a $ 20kTT car and drive it, no problem, so don't know anything about your car.

You be spending a lot of time looking for used parts as well. Even w/ used parts it still adds up. Especially if your goin for a 6spd swap, you'll need a complete 6spd rearend which is very hard to find. For me i rather have my car on the road asap instead of in the garage for months.

I have been looking into this swap myself. I'm thinking about picking up a JDM 2jz-gte with auto trans. and yes i have a 98 :)
the things I was poundering is if i wanted to get a non vvt-i or spend a little extra and get a vvt-i.

the one thing i didn't see anyone mention is the rear diff. I was lead to belive you had to change that., or maybe that's only if you goto a 6speed?

Yes, you have to change to TT auto differential.
NOT recommended to use NA differential, if you do change to TT auto differential , you have to get new axle haftshaft left & right to fit with TT Auto differential.
later
