No matter what you're going to have to make some modifications. I modified my 1jz harness with all new connectors and wiring to plug into a 2jz ecu (with some help from a local). The 2jz ecu is nice but get an upgraded one with a higher redline as my current ~6200 rpm revlimit is ridiculous.

Don't waste your money modding the 7m if you're already planning on going JZ, doing a FFIM setup is like 1/3 of a stock 1jz swap.

Same here. Running a walbro pump, mkiv 550's, afpr and the bypass line. No issues.

Stick with the r154.

The radiators are the same no matter what fan you use. The hydro-fan bolts on just the same as the mechanical fan shroud. The only difference is the lower temp sensor for the hydrofan ecu which is "optional".

Stock.

Don't be cocky, chip is right. If the car doesn't even crank then it is not a problem with the ECU. However... I did once have a problem with wiring where the fuel injectors stuck open causing the motor to fill with fuel, then it wouldn't crank because the motor was hydrolocked. Pull your...

You take both out as neither stay with the JZ swap.

I am currently running a map ecu 2 on a 2jz ecu, on a single turbo 1jz, with 2jz cams. My thoughts are pretty simple and I think will be beneficial to anyone who thinks like I do! I didn't want to stick with a 1jz ecu because they seem to go bad eventually on every car. So any plan that...

Here is a link I bookmarked back when I did my 550's: http://www.supraforums.com/forum/showthread.php?t=170792&highlight=resistor+wiring

Search Hydro Fan here, a ton of people are running this as they were OEM on 1jz cars. Don't know what info you're looking for but they aren't really rare at all. And instead of linking us to SF why didn't you just copy your post here? Did you even search first?

Did you pull fuel? Also even though it isn't going to help your problem at the moment, bump your fuel pressure back up to 43-45 psi, or it will never run right on a stock 1j ecu.

What are you using to tune it?

I had this when I got my first supra, pulled off the panel and saw a stud with no nut on it, and a nut sitting at the bottom of the inside of the door. Threw it on and bam! No more wobble. I would just suggest pulling off the door panel and move your window by hand, you should be able to see...

Yup pump gas 18psi, starting to feel really slow in this 100 degree weather! Hopefully going to upgrade the fuel system soon and be able to run e85 or race gas through it. edit: Oh, and I am controlling timing with the map ecu 2, but I only have it retarded about 2 degrees across the board for...

Pretty simple setup, garret 61mm, 550's, walbro, 2jz cams, Drewgo equal length manifold, 2jz ecu and map ecu2.

http://www.youtube.com/watch?v=8nrcXv4ebSY I recently got a 4" exhaust, finally got a video of what it sounds like from outside. There is a small exhaust leak that I need to get fixed, you can hear it a little in the video. Let me know what you think! In-car with my friend narrating lol...

Yup I ran into the problem under the same circumstances (but with 550's). Problem was running lower than stock fuel pressure on the stock ECU. Raised it back up to ~43-45 and with super minimal adjustments on the neo it was smooth all the way up!

I wonder why everyone thinks MK3 owners are so cheap? Don't use hockey pucks you moron.

Great information, but the shroudless fans aren't going to cut it. It'll be 50% the performance of the hydrofan if you just leave it as pictured. 2x12" fans might "fit" well, but it would be a better idea to find something with a shroud, like this: And you have to be really careful on your...
