can someone point me in the right direction?
Ok, so I have a Mk3 Supra, trying to swap in a VVT-i 2JZGE into it, and I have a bunch of questions about swapping the auto for a 5 speed....I know many poeple have done this, but is there a section that is appointed for these topics?

Lol, this is funny cause they told me to come to you guys....reason being is...its a IS300 VVT-i engine....and its auto harness, I would imagine someone on here has swapped the tranny to a 5 speed, and done something with the E.C.U.. I was told the E.C.U. will go into something called "limp mode" if it realizes there is no auto tranny hooked to it. I was suggested swapping the E.C.U....for a 5 speed E.C.U. on out of a "Aristo" I believe its called....but they warned that it my not work for the NA harness....cause the "Aristo" was a turbo car, again another wall to get over. So I will continue looking as my motor gathers dust

The reason the car goes into limp-mode is because the ECU no longer recognizes the transmission. Bypassing the neutral-safety switch should take care of this problem and you should be able to keep the ECU without spending the extra money to get a new ECU, have it reflashed and have your keys reprogrammed.

I believe you can keep the auto ECU that is with the engine and just bypass the neutral-safety switch.

Haha never mind about the keys
Hmm, I'm not entirely sure about this either but I wonder how the ECU and everything will interact considering the 2jz-ge vvt-i out of the IS300 is drive-by-wire? (I think?
)
I'm assuming that you would not want to have electronic throttle control with the 5sp (I don't even know if that would work).
The wiring may be more complicated than I originally thought considering all the components that are electronically controlled. Bypassing the neutral-safety switch and have the basic wiring done; you could probably get the engine to work but I fear that the ECU will start throwing codes for everything else - the ECUs throw codes for the tiniest thing that's off and I'm not sure if that will trigger limp-mode or not (again, the drive-by-wire issue).
Hopefully some other people can chime in on this that are more familiar with swaps.
BTW, I just googled "IS300 2jz-ge swap", "2jz-ge ECU", and other key words specific to your swap and found some other forums (supramania, toyota/cressida) with others that have started similar swaps. You could check those out too.

ok guys, so at work, I started talking about my little situation I have here.... and my friend with a corolla (a hole lot less techinally advanced) but he swapped his auto tranny to a 5 speed....but had to wire in a 2 leg switch, to by pass the neutral start switch. So i think I may have something here.....
