Guys,

Is there anything that would prevent me from buying the turbos and exhaust manifolds from a supra and fitting them up to a nat asp 3.0 litre in my 93 GS3? I'd rather not go through an entire swap... I am just wondering what would be the blocking issues... if any...

Thank you,

Brian

 

Uh Yeah, Manifold won't bolt up to head. I believe turbos will hit firewall

 

Yeah Turbogs is right. The 2JZGTE stuff will not work on a GE engine, they are completly different bolt patterns. As for a manifold that will fit a N/A supra, it should fit the GS. I plan on getting mine for Powerhouseracing.com

 

I'm losing you guys here. Isn't the manifold the only part that bolts up? LIke ABear said, same bolt pattern. I'd imagine exhaust pipes etc could be custom fashioned. What other considerations would there be? Sorry for the newb questions - I am just curious what else is involved. Pictures would be helpful if anyone has them available.

 

Same bolt pattern on the intake manifold, not the exhaust manifold. One side is completely different, I'm pretty sure it's the exhaust, The intake side of the head is the same, i believe.

 

I think that both sides are different, but Im a defenitly sure that the exhaust side is different.

As far as other considerations, you would have to a complete turbo back custom exhaust if you want the car to breathe right. Maybe not entirely custom as in you could get an aftermarket exhaust and fabricate it to work with the downpipe off the turbo.

Heres the thing, what you thinking of is will a supras twin turbo setup work on a GS300? no it will not. If you are planning to go turbo you need to do ALOT of research, theres more than just "slappin" on a turbo and going, as I have learned. I have been doing alot of searching and been learning alot.

 

The exhaust manifold stud location on the GTE and the GE head are different, not to mention that the GE has a distributor in the way also. The intake manifold stud locations are different also.. different runner spacing. Nothing from the GTE head will just "bolt-on" to the GE head.

For the quickest, easiest way to turbo your GS.. check out posts by SuprRunner. He just turbo'd his 93 GS300 in a matter of hours and at a relatively low cost. Very effective.

I will say this. Cheap and on a budget is not the way to go into a turbo system. You dont have to buy the best stuff, but don't buy Ebay turbos..etc.. either. Best of luck.

 

Will the supra mk4 NA-T stuff not be adaptable for use on a GS? I am gathering that there are bulkhead differences between the GS and its aristo brother to with getting in the way of turbo's but like I said there is always adaptability. A custom decat downpipe can carry the turbo outlet housing to the cat back exhaust system to marry the NA-T kit to the GS exhaust system. Any piggy back fuel solution is going to need mapping regardless of if its a supra or GS. AFAIK suprastore, MVP, and many others carry these kits.

Intercooler placement may also need addressing but if you aren't afraid of a bit of legwork you should be able to sort this out easily enough. On supra's a TT transplant is a serious option and I have read somewhere of people doing the same between the aristo and GS.

 

SEARCH!!! It's been covered

 

Well, as you know since you have one in your driveway, the Aristo is a 2 jzgte engine.. almost identical to the Supra TT. The blocks are the same, but the head is the major difference, as the manifolds are both a different design and won't interchange. A lot of the NA-T Supra kits may work, but it depends on the size and location of the turbo, since all of the 1st gen 2jzge GS300's had a distributor to deal with.

As far as the rest.. that is easy.. 255 lph fuel pump to replace the stocker.. a set of 440s, and an SAFC (piggyback fuel computer). Any good shop should be able to fab an intercooler solution..dont forget the bumper support.

If you want more NA-T info, search on the SC300 forum.. the members there has the same engine as the GS300 and the same issues to deal with, and the NA-T's over there probably outnumber the GS guys 3:1.
