The aristo and supra 2jzgte
 

Ifinally got some bread up but I now cantfind a supra 2j. I found a cheap 2j from an aristo. 2jzgte. The only thing I know is the aristo has the vvt, like honda vtech. I think it's differnt in some other ways but I don't know. I think the later supras had vvt too. I would love to hear what everyone have to say. I'll take my time filtering out the bull sh... lol. Most of you guys are pretty smart.
:o

I guess what you need to do depends partly on what you're putting the motor into. This thread has some good points that might give you ideas: http://www.mkivforums.com/vb/showthr...6&page=1&pp=10

I'm sorry Im putting it into my old supra (mk3)

the only differences in the 2j's are the oil squirters, the oil pans, jdm(aristo) gets screwed on cams injectors and ebay quality twins but the internals are still solid and the same.. so if u can find a cheap aristo setup...
just check on supraforums.com and buy...

1. set of USDM twins(if your not gng single right off the abt)
2. USDM cams.. or 272's are gng cheap used nowadays
3. USDM injectors or some 550's



as far as your swap goes are you gng to sell your first born and buy a 6 speed? or jsut use the MKIII turbo (r154) tranny with the swap?

then 1jz bell housing, 1jz flywheel and 7mgte clutch ...and depending on your rear end.. u should be good to somwhere around 500-700 wheel.. depending on your driving habits and weather or not u use slicks.

and i think u ahve to use a front sump pan (aristo) because of the cross member on the supra.. dont quote me on that.. i am not to sure


and jsut relized you ahve the tranny already... my bad

That's Right. I will go wit the r154 /w 1j flywheel combo. I will get a single But I am debating it , I could 2 save money. but It would be easyer. I will use my custom 3" exhaust and see how things go. Thanks for the info!!!!! I will check about the sump and cams.

I thought They use 550cc's... are they 440? I dont think so. well.. thanks.
:supz:

usdm are 440cc .....

depends on what your going to do... you MKIII at full bpu would be pretty meaty.

idk what your into... i kno up here in cleveland straight line racing is dominant... so its either a dig or 60 roll.
either way usdm twins in that car is going to do u decently...and def be cheaper.

WELL THIS MOTOR IS A JDM Aristo 2JZGTE.

I thought All 2j turbos only had 550cc.

i know my mk3 has 440cc.

non turbos 2jz Idon't know.

:eek: dose anyone knows for sure...

what about the elec. is it the same?

The 440 vs 550 issue comes in since the JDM 2JZGTE motors have smaller injectors (440) which are high impedance vs USDM larger injectors (550) which are low impedance - so you can't just swap out injectors without adapting impedance or swapping out the ecu's; plus the other points Instigator mentioned above for the JDM setup like slightly less aggressive cams, and the ceramic turbo wheels vs the steel wheels on the USDM turbos.

Why not just find a US motor? Why get a one from a JDM junkyard when you can get one from a US junkyard or possibly someone who's swapping engines for one reason or another.

And mk3 needs a rear sump setup.

That is all very informative.

first I will use my original ecu from the mk3. the wire harness will be adapted to work.

The reason I am using jdm is I haven't found one for $1700 (including shipping) if you have one let me know. I would prefer that.
:eek:

yOU SAID i WILL NEED A SUMP setup? explain...

^ the sump setup refers to where in the oil pan the oil pickup arm is located. On some cars it's in the front end of the oil pan, others it's in the rear end of the oil pan, and the oil pan dimensions change to accomodate this. This can be an issue as far as frame, steering and suspension clearances. I forget which is which but the TT and Aristo are opposite in this regard.

Why would you use the Mk3 ecu for a 7m on a 2jz? That makes no sense at all.

And what Nick said about the sump. I'm not sure, but I think that Supra and Soarer 2jz are rear sump like the Mk3.

usdm is rear sump... aristo is front sump.

.. considering ur gng to have to splice in the 2js engine harness to the mkIII interrior harness....... but good luck making that work.

This company specializes in converting wire harnesses. u send it out ... and plug and play into 7m ecu.( keepin it 7 real!!!)

I don't have the balls to do that myself. :(
wish I did...maybe not.

I will use modifided custom motor mounts for the swap. would that take care of the sump issue? I won't change the crossmember. I don't think that's an issue in my case. if I'm wrong let me know.

I welcome all critisim. no woulda shoulda when I'm done. lol

Good luck making that work? 240 and GC owners do that with every single swap and there is more than enough information just on their forums to make it work. There are also companies which can have the harness merged in a day and have it back to you asap.

I hope you're doing research in other places than on here. Because otherwise, you're probably going to be screwed. Not saying that people don't know what they're talking about in this thread, I'm just saying there's a ton of info out there on this and it should be pretty simple to do.

Why are you using the 7m ecu? I think that's a stupid idea? If you're "keepin it 7 real" then why not keep the 7m? Use a 2j ecu with the 2j. Get the engine with a wiring harness and coils/igniters/whatever it uses or needs and an ecu. And then put that in the car. Then you just have to wire the 2j harness to the chassis harness and you're done.

If the aristo is front sump, the oil pan is going to want to sit right where the crossmember is. So unless you're motor mounts are raising the engine 6" and you're getting a new hood with it, you're going to need to do something. So you're using the pre89 crossmember? Wouldn't it be easier with the 89+ one? Isn't the engine mounting pretty similar if you do that?

Go on other forums and do a lot more research. It doesn't sound like you're ready for something like this at all. Or save the pennies and pay someone to do the whole thing for you.

I'm sorry I won't use the 7m ecu. they will use the ecu from the 2j. it won't be 7real :roll:

And the motor mount prob. my mistake :) that's solved with a 1jz pan.

it will fit in no prob. :thumbup:

and I use 1j flywheel and bolts.

no need to be afraid..."when fear grabs you grab it by the nuts."

jesus h c..... rick i went thru this already with you.dude i could tell for sure aristo sump pumps are in the front.sothat knocks out that swap unless you retro fit with a supra/sc300 one.plus i could wire that up for you with know problem.

YUP, UHUH. YOU HAVE A POINT CHEIF. :-p
