Can I swap a Twin Turbo 2JZE engine and 6 spd tranny into my 88 Supra? Any info or experiance on this swap?

Thanks for your time

For the transmission, you will need to bang out the tranny tunnel as well as cut the hole where the shifter comes out of an inch or so because the tranny is a bit longer than the auto. It would take extensive modification on the wiring harness to make everything work correctly. You would also need to bang in the firewall a little. The rear turbo wont fit.

But yes, it is very possible. And there are quite a few guys out there with 2jz MKIIIs. Just need some money.

its totally possible. i was at the nopi event last weekend at the maryland international raceway (mir) and there was a mkiii supra with a 2jz, it was in the pro class and ran a 9! a 9! i wanted to just hump it

Ok, so the 2Jz swap seems more like a head ache then I need. I dont want to F*** with my fire wall, or my wire harness if I can help it. So it sounds like my best bet is to buy a JDM 7MGTE? is the correct? Im also still wanting to g 5 speed. Do I still have to do all the tunnel and shifter hole modifications if I still with the tranny matching the 7MGTE? Also, I was looking into ways to twin turbo the 7MGTE. I came up with a company that makes Turbos that mount under your car! has anyone had any experiance with these?


Thanks

You'd still need to trim the hole about an inch. Ive never heard of a company that does it. Just keep the turbos where they are supposed to be. And in my opinion, Id stay with a single turbo. There is a reason the MKIV guys go to a single turbo. But yea, the idea of a TT 7M is cool. There is a guy on the other forum with one. He has a buildup thread and all that.

i say stick to a single turbo. unless you have extensive knowledge of engines and motors i would leave the thinking to toyota. i just bought a jdm 7mgte, ill keep you guys posted once i begin my work on it.

If you're really desperate for a 6-speed box, i know Quaife sometimes have gearboxes available that are direct replacement for the factory unit - but have different internals. I had a UKDM Ford Type-9 Style 5-speed in my Sierra XR4x4, and after the engine swap (2.8litre 160bhp OHV V6 came out, 550bhp 3.0 litre 24v QOHC V6 went in), the box was the next thing on my list. Quaife did, and to my knowledge still does, a 6-speed version of the box, made with all alloy main case, alloy belhousing & quaife's own transfer box tailhousing. Cost the better part of ?6000 (about $9500?) but damn it's a good box. Virtually indestructible!

I suppose all i'm trying to say, is check out Quaife :P
