Project Thread 1UZ-T MK4 Supra

[ugp]

Just got around to posting a project thread, I'll fill in all of the blanks tonight and do a full write up. For now, here's the only old picture of it that I can find:

It currently lives in this:

That's a huge turbo. Good project! Let me know as it's going along.

Beautiful MK4 supra you have there. What are your HP and TQ goals?

 

[ugp]

Thanks for the comments guys. I'm hoping for 1100. It ran 980 on a pair of smaller turbo's.

I'm awaiting new engine mounts and some ARP flywheel bolts.

Do you mean you had 980 hp on that 1UZ in that supra?

 

[ugp]

That's correct.

Nice! Please post more pictures of the old build and the new build.

Curious if you had any overheating issues and what your cooling system looks like? Could you describe any changes/upgrades that you made in that area?

 

[ugp]

Koyo radiator with twin electric fans and a stat that opened at 75 ish were the only changes made.

Temperatures sat at 85, rising to around 94 on full chat in short bursts. Long runs would have it creep upto 100, by this point both fans are on full tick (on at 87, off at 85).

These temps were reported by the stock sensor into the megasquirt, so I've no idea if they're exactly accurate.

I'll post pictures when I've got this build done.

I assume no air conditioning for this car?

 

[ugp]

It's not something that's really required. The hottest it ever get's here is 20 degrees C, so as long as the heaters work I'm chuffed . If we do get a sunny day the roof will be coming off (it's a targa top).

 

[stevechumo]

It's a big single turbo. Nice!

 

[poorsupra]

what have you done to the internals? block and head if you dont mind sharing. i love the potential of the 1uz!

Blimey, not updated this in a while. Finally on the road and MOT'd. I've a couple more dyne sessions booked once I change the wastgate springs over, hoping to crack 1000bhp, but that won't be happening until the spring appears and all the salt goes.

Also in dire need of a the suspension setting up, it's like bambi on ice trying to lay any power down at the moment.

Here is the MKIV Supra suspension setup, AKA the Lance setup. Basically it's no toe on front, with all the caster (5 degrees) you can crank in, and minimum toe at the rear.

Camber settings aren't anything wild. 1 degree per wheel up front and 1.5 per wheel in back.

This is designed for good stable handling, and it should result in pretty light steering with all the caster, and even wear on tires. Those may not be your goals, but in lieu of anything else, it's a good start.

Give the image a click & it should open up into a new window where you can actually read it.

Thanks for this, I've been trying to find it for a while.

Here's a quick video of it as part of the monthly fire up.
