Yes i would like to know that too. Is it really expensive to charge a 1uz? It seems like if you dont mind using some ebay parts you can get away with 3gs or less. Alot of those ebay parts have been proven to work well too

iron retains heat better than steel so dont worry about that theres a reason oem turbo cars have cast iron manifolds from factory.... welding steel on the iron though will result in some name calling but it will work just fine if done right. but like said airflow wont be the greatest. supposedly the stock cast manifolds are able to be flipped around and mounted up and you can create your "custom" rigged manifold from there. edit: (didnt read im being redundant!)

whenever i join the airforce and have a good income again i will be attempting my own single 1uz. long wayyyy away.


just do it! no more questions!!!!!!! dont go 1j or 2jz!

imagine a single 1uz with a quick spool valve!!

are you looking at actually trying to gain power or prestiege? Because Im not sure I would turbo the 1uz.. more likely Supercharge it.. but then i guess i cant say one of the very very few that spent the kinda money needed to turbo it..
Just wondering what swung you to the Turbo route?

MrHimbert

I wanted to supercharge it first because it was done bfore by quite a few. But then an old thread on here about a guy putting a single t70 on his sc4 sparked my interest. But i dont think it was ever finished, he doesnt answer pms and the thread is pretty dead. Plus ive always wanted a turbo car. And the fact that nObody has really done it interests me even more.

I turbo'ed my 1uz swapped MKIII supra. The mods are as follows:

HX35 from Cummins
295cc injectors from MKIII NA
8:1 FMU
SAFC Neo
Walboro pump
w58 Transmission

I ran 9 psi on this setup, spooled hard and fast, and was fun to drive.

Was it reliable? Hell yes, I drove the car to dallas and back in one day (three hours one way), the only issue I had was space, and running a pump for the oil return.

You might wanna roll over to lextreme forums, and you can also search my posts (I use the same user name everywhere lol).

Unfortunately, the supra got into a fight with a semi, and it lost, so I'm back to a SC400. I haven't decided whether I want to boost it or not, but I do know I'm going manual once I finish sourcing the parts.

MrHimbert

Nice! I will def check that out! How did u do the manifolds on it?

Man I wish I had an extra sc400 just to mock up some turbo manifolds on. Id use the header flanges & use probably a straight solid 2" tube of steel. Like 3/16th to 3/8 thick so they would take the heat. Make some 2" angled to the back runners & then put a turbo flang port @ the rear on the bottom . Use 2 small turbo's like the 300zx turbo's. Then you dont have all the other fitment issues up front. I mean cause if our only gonna run 5-6 lbs that would be total sufficient.

MrHimbert

nah im trying to go with a big single....i dont have access to shop equipment...so im hoping i can find someone that has done this before that is willing to help me out, and make a few hundred dollars too...

Pretty much the same Carlos did it, I flipped the exhaust manifolds so they were front facing.

However, in the SC4, I don't think it would be a good idea, it worked great in my MKIII, but I didn't have power steering, or A/C to worry about.

If anything, move to electric power steering, relocate both the alternator, and A/C compressor and we should have a go.

Alternatively if you are going big single, instead of making a pipe that joins the headers together, you might want to do it stevechumo style.

Leave one header how it is, and modify the other bank. So what stevechumo did was left bank, went into the right bank, into what he called a "saxophone" lol.

He's on lextreme too, take a look at his build thread

Only one real attempt??? I guess you had a hard time with the search button???

Due to the need for so many one-offs...It is difficult to complete a Turbo 1UZ project in a short time frame...It would be helpful if you can weld and fabricate well...

Biggest tip: Be very wary of the fabricators and welders that claim to be able to do this job...They not only need to be very good at what they do, but they need to be of high integrity, or you will lose lots of time and money.

You can probably run 10 to 12, maybe up to 15 lbs safely on the stock internals...As long as you have comprehensive engine management, and a real solid tune from an expert tuner.

The TTC manifolds are solid and they absolutely clear the AC...I ought to know since their manifolds and their jig were made from my original TT manifolds from my Stage I set up, which did run well (But it was untuned, so low boost was my only option). I do not know how much of the plumbing Eric provides, but you should still be able to fabricate and fit 3" tubing with no issues and clear the AC, the power steering, etc. I would not do a 2" set up...too restrictive.

Steve Chumo's set up is excellent, and he did not have a TT but a single set up.

Besides the TTC manifolds, I do not know of any that are ready made...But, for that price, check with a good fabricator and see if he will fab up a set for a much better price...Use stainless if you can spare the budget...

It is expensive...Also depends upon the level of quality and showmanship you want too...I would stay away from ebay parts...Cheap Chinese made in most cases, and will not hold up in most cases...

I beg to differ...

thanks for the advice, but as far as i see, you have two turbos, i was meaning to reference a single turbo set up. i was also under the impression that steves was a twin turbo also, but maybe i should look into it. thanks again. also, so you used your stock manifolds, just swapped them and ran low boost and it was good to go? are you talking like 5-6 psi?

I agree, I think your search button must be broken!

Sc400tt, I have a question, and I'm sure OP will find this useful as well. What EMS do you recommend. I am starting with an r154 first, but plan to run a pair of Garrett t25's from an s13 around 12-13 psi of boost, but am clueless as on EMS.
Also for turbo coolant drain lines, where do you tap into the cooling system for the turbo inlet and turbo outlet?
For turbo oil lines, are the inlet oil lines T'd from the oil pressure sensor? And the drain lines on each side of the lower oil pan?
I believe it is your setup on Lextreme that I found the turbo oil outlet locations
Thanks
