I have searching since the whole week end ,but it seems like no one ran ino this before!!!!!
Ok guys i am running into a little problem
I picked up a 94 USDM Supra Gte engine: no ecu ,no thans,and the harness i cut in the middle so my question are:

*Can my half cut harness be extended,mated with the SC harness?
*What auto trans can i use if i don't find the Supra TT auto.
*What ECU can i use if i don't find TT ECU .
Please don't tell me to search i already did.
Thanks Guys

1) If you just replace the cut wires then you can do w/e you want with the harness
2) you can use your current auto tranny.
3) Not sure, i would just get the ecu. I think for the manual cars, you can use a 2jz ge manual ecu and use a piggyback ecu and hook up the gte engine as an na-t setup.

1. Its possible, but good luck since its cut in half. Do you have both halfs?
2. Do you want to stay Auto?
3. You need a TT (must be USDM) ECU or a standalone.

You have a PM

My current trans took a dump.
I dont have the other half of the harness.
I wanna stay auto for now.
I don't wanna use any other engine managent,i want to stay the tt ecu.

Try to find another harness and send the stock SC3 harness and TT harness to Dr. Tweak. He did my harness car fired up first try with no CEL. You can use an Aristo harness also if you can find one. Used Supra harnesses go for around 500 on Supraforums.

I didn't know i could use the aristo harness.
How about the Aristo ECU ,will that work with my set up ?
cause it's almost impossible to find a Supra TT auto ecu.

Yes you have to get in touch with Dr. Tweak about the specifics of using the Aristo harness. Put a WTB ad on supraforums for the auto TT ecu and one should come up.

Aristo ecu will work and you wont have to use the airflow meter as it is map sensor based system.

Thanks for all the help guys ,i think i am got a different route
It is going to cost me a fortune if i do the swap .
*Supra GTE $1200
*Harness $300 + 420 for extension
or the CUT harness rewired $800
*R154 $500
*Bell housing $350
*R154 extension $350
*Clutch ...Flywheel....etc $1000
*Intercooler $400
*Turbo $1200
*WG $350
*BV $250
*Clamps, hoses,return lines $250
*Drive shaft $50
*Dpipe $250
*Pedal assm ,Clutch Master Cylinder etc.. $400
*97 conversion $750
* Seats $1200
*Body shop $3000
*TT pumpkin $800
*TT brakes $800
*Wheels $2000
*Injector $600
all this $ 16500 we are not done yet
correct me if am wrong or missing something. I will need majority of those parts i was gonna stay auto but i want a 550Rwhp DD that's why i choose R154 cause i dont have $5000 for the V160.
So this is why i choose to go a different route lol

SCoupe

I'm just a little confused how the nearly $7,000 listed for: contribute to make the 550whp goal. Swapping the r154 for the auto is a big outlay also.

That base 2jzgte with a mid-sized single turbo will deliver a potent 425-450 whp. That next 100hp to 550 brings on a whole new level of upgrade requirements and money. If you're new to this much power, 400+ is a very potent place to be.

Ok maybe i didn't say it the right way lol
If i want my car to get to the point where i want it to be i need to spend the amount above.

I never had a 400+hp to be honest but my brother had an the new M5 which i get to drive whenever.And the SC is will just be my week end car, i drive my GS twice or 3 times a week.
I see where you coming from that why i changed my mind.

Your shop doesn't know that motor very well.

You should replace the oil pump.

The HG only goes on one way, if you can't figure it out, take it to someone and have them finish it.

Might be a good idea to keep your newly rebuilt parts away from all the old oiled up/grimey parts and off the floor.

I am doing the work in my garage !!!!!


Ok i talk to a lot of local guys and they told me that the 2JZ oil pump doesnt often go bad ,if its not bad dont replace it.

I already figure it out thanks for the advice tho.
