I know this is a SC 300 Forum, I heard alot of guys in this forum have done Turbo Conversions...Will the Exhaust Manifold & Turbos From a 94 Twin Turbo Supra Fit my GS300?? A Buddy of mines just crashed his Twin Turbo Supra and he's willing to sell the Turbos and exhaust manifold to me...Will those parts bolt right up to my motor? Will his Intercooler fit my car if i got all the bolts and brackets? What other parts will i need from the Twin Turbo Supra to make it work on my car?

No they will not fit engine are different.

If you get the Head off of the GTE you can use everything off of the Supra, complete turbo manifold w/ turbos, intake manifold, TB .....everything

You will need the wireing harness and ecu.

or run the two or three extra wires yourself; hardly any difference in the GE and GTE wiring harnesses

for all that info; it'd prolly be a good idea to buy Phil Auldrige's book

Wouldnt that be a waste to swap the head out since your still going to have high compression pistons. That is unless you just want the bling factor of twin turbos which is cool too i guess. Ask him how much for the entire engine.

actually swapping the head and consequently the head gasket from a SupraTT will lower your CR to a 8.875:1 theoretically...

the pistons aren't what raise the CR in this motor so much; its the headgasket

Is the GTE head a direct fit onto the GE block? That would be something I would definetly consider.

Ahh... Hello.. Changing the head to the Supra's tt head, and wouldn't it require a new head gasket? Simply slap on a tt headgasket or an aftermarket 2.0 mm and up. that'll solve the compression. But I just don't think it's as simple as that to swap over everything from the tt supra. You should just purchase the single turbo for the na 3.0 engine.

I've talked to alot of different people in the na-t comunity on which route to take. Either go Na-t, GTE swap, etc. Some of them say they wish they would of just done the gte swap, and others vice versa. But I've done the price break down on all the parts I would need to go Na-t and it works out almost the same, with the exception of having a built block on the Na-t route. In my mind it would just be cheaper for you to keep the Ge head and go single on your gs.-pdang

I have been doing a little research and I believe the 2JZ GTE will not fit in a GS. I believe there is a clearance problem with the rear turbo which will require you to go with a single. At this point why spend the $$ for a TT motor when you can just use the GS motor. I have been trying do deside what to do with the drive train of my damaged TT Supra and this is one of the things I found out. Here is the link to my soon to be departed TT:

Good luck with your GS project,.

Built block? Not really, just lowered compression.

Wow, that must have been some hit to your Supra. I would buy an SC300 and swap everything out. Seats, rims, brakes, motor, tranny, etc etc will fit in.
