Bump! I added jm94tt's awesome write up. We still need more info to add to the thread.

MattSEG

Still working on this guys, just got a little derailed.

sc250tt

wonderful write up guys I dont think ineed to add anything you guys got mostly everything .Is this going to be a sticky because this is the most information ever shared about this swap

MattSEG

Anyone have more info about the remaining questions?

I'm looking for some information about:
intercooler sizing.
Info about walbro vs mark IV fuel pump.
Fuel line information (since you need at least some)
Battery relocation
A definite answer about if you need to swap radiators, and sizing.
Information on keeping AC.
Electric fan information (though not necessary for the swap)
Reliability alterations that are good to do while doing the swap (oil cooler, etc).
Making a step by step (not down to nut and bolt) directions for the swap. Especially the 'prep work' like lengthening the harness.
And of course anything else you can think of.

Where are some good places to find a 1jz clip?

Aka Post 8 of this thread. I hope that helps. There are a million importers out there, and some are obviously more reputable than others. Personally I got mine from a fellow that accidentally ordered a soarer 1j for his mkIII supra.

If anyone has more reputable vendors please tell me and I'll update that post.

I had some other pressing stuff to take care of, but now I'm kicking it back into high gear since I'll be looking to do my swap soon.

Again, if anyone has anything to add please do.

tiger japanese is horrible to deal with, and they are liars. i'd reccomend never buying anyting from them, and they should be removed fro mthis list so no one gets screwed like a friend of mine did with his RB motor

I just recently purchased a soarer engine from jhot. They were super quick and included a bunch of stuff, like side mount intercooler, that i wasn't expecting.

Still looking for more information guys. If anyone has stuff to add please post or PM me

I just finished my sc400 1jz swap!!!!! i just had the front clip. And the driveshaft from a sc300 and everything else seemed to just work!!! BUt that air bag light is staying constantly, like always, even when the car is sitting over night. its kinda crazy. im thinking about just pulling the bulb. OH yea and the 1jz is insanly quicker then the v8.

MattSEG

That awesome to hear!!!! What part of Tejas are you in?

Seriously post any info you can, hell, if you wanna give me a ring I'll take dictation and post it. If you have any pics or anything else please post too.

Congrats on getting the swap done!!!

i wish i can do something like this... =\

bump! for good info

MattSEG

Added a link to Phoenix Tuning.

Which begs another question...

Of what I understand if you put a hole in the firewall you can bypass having to lengthen the harness which seems to take out a gang of potential demons. What I mean is routing the wires through a new hole would keep you from having to stretch it to the opposite side, while you'd have to put the ecu in a different place it seems as though the small headache of that would more than make up for the effort of lengthening the harness as well as all the potential problems that could arise from that... why don't I see people doing that?

hey i have a 91 supra with a 1jz and i have no clue how to tune it it seems to be slower than when i first got it i have a greddy prosfec b spec 2 and an HKS fuel cut defencer and when i put it to the floor a warning comes on my boost controler and it jumps around if anyone can help i would really appresiate it

MattSEG

What kind of warning? Are you hitting scramble? Do you have your boost controller set up right?
