is your 2JZGTE engine from the Supra TT or Aristo (JDM)?? I am going to get the Aristo 2JZGTE soon and i need some advice on what i should be aware of.....thx

JZS147

flm, my engine is from 95 US supra twinturbo. It would be better if you get Aristo engine because the location of the oil pan is different from Aristo and the supra. if you get a supra engine, you'll have to look for aristo oil pan and things that goes around it like I did. by the way, is your GS 1st gen or 2nd gen? if you have first gen, go with non-vvti, if you have 2nd gen go with vvti like v300.

i have the first gen GS....also should i get the tranny as well?? or stay with the NA auto?? I hope it can handle all the power thanks

JZS147

well, I went with supra tranny. if you are going with supra tranny, the driveshaft has to be modified. it would be better if you find aristo tranny so you don't have to modify anything.

JZS147, your car sounds like a beast, do you have any pictures of it??

Did you do al the modifications yourself?

v300

You ARE my 11sec GS counterpart.

flm

is it possible to stay with the GS300 auto tranny???

JZS147

flm, it is possible to stay with GS300 tranny but I wouldn't push that much hp if I were you.

flm

cooooool.....so all I need is the engine, harness, ecu....
is it hard to do the swap?

JZS147

well the block and the head will drop right in but the stock twin turbo will not fit because of the firewall. in order to make it work, you'll have to get single turbo upgrade or modify the stock twin turbo manifold. also if you go with turbo upgrade, you'll have to get the intercooler, upgraded ecu, etc, etc, etc.

Richie, sorry, this is the only picture I have. this is from last november when the shop that I took it to was still working on it. but I would not recommend this shop at all, they screwed up my car and v300's car.

flm

even if i get the Aristo 2JZGTE engine I still need to modifly my firewall???
nice car by the way

JZS147

yes, because japanese right hand drive aristo's firewall comes out on left side where the intake manifold and left hand drive GS comes out on right side by the exhaust manifold. it sticks out because heater core is right behind the firewall. you can try to push it in but at same time you might break the heater core unless you take the heater core out. if you do take it out, the heater will not work after that. also if you try to put the stock twin, I just remembered that it will also hit the ABS pump located right under the airfilter and it is really hard to relocate the ABS pump. the easiest but costly way to do is just go with single turbo upgrade. this way it will clear from the firewall and the ABS pump.

JZS147

oh yeah, and the harness might not work because its designed for the Japanese RIGHT hand drive where the ecu is in left side and US LEFT hand GS is located in right side. if you want to use the Aristo harness, you'll have to do some modification.

Hmmm, very intersting thread...here's something for you if you're interested in converting a JZS14x GS300 into a JDM spec turbo JZS14x
