Any time you add boost of more than about 6 psi on any non turbo motor, I have to recomend a new ECU. Either a factory ECU that knows boost, or a programmable system. Piggy back controllers and rising rate regulators can work up to about 6 or 8 psi, but beyond that,m you need a boost ECU. I...

The toughest part about using two intake tracts is that they probably won't balance perfectly. As long as it is a single plenum, then a MAP sensor based ECU will work fine, but AFM systems will be a problem. If you used 2 MAF sensors (The early Lexus sensors are Karmen Votex air velocity meters...

I forgot if your car was IRS or solid rear axle. It makes a big difference on what you need to do for traction. My car is IRS and it puts very equal power to both tires, even when the LSD is fried. When I have tried to do a burn out, the black streaks from both tires are very close to the same...

Thanks Peewee. My friend is working on getting the Fuel Pump ECU (FPE?) connected, but having its output just pull in a relay that will run my pump. The book show only a single error code for the FPE if it does not send the DI signal back. The tests for this code are really dumb. Basically you...

My 22RE turbo motor had a unique manifold setup. I used the stock cast iron 4 into 2 section that had about 1.2 inch id ports at the head and 2 holes about 1.4 inches at the bottom. It was fairly smooth inside and was a proper 1/4 2/3 pairing with about 14 inches from each port to the flange. I...

I posted an update, some questions, and then some pics, and it all went away ;-( I will try to repost the pics (down rez'd this time) in a day or so. But I wil re-ask my questions here. 1) Do I need to do anything with the TRAC ABS or Cruise wires from the ECU? 2) Can I just plug the tiny...

I am finally getting close to firing up my 1UZFE Celica swap and I have a couple questions. I posted this a few days ago, but I see the forum must have crapped as all my posts including pics of the swap have been lost, so I am re asking my questions and should get the pics re-sent soon. I will...

It will be very interesting to see what I end up getting in the Celica. With my turbo 22RE running 8.4 compression and a lopey cam it would get 25 mpg on normal driving. Got as high as 28. 5 on all highway and as low as 20 mpg even on a race weekend with two drivers. Now to convert to litres/100...

If I was not 2500 miles away from my car, I would gladly take a ton of pics and post everything. I have a trip planned to visit my car (as well as my familly) in April. i will get a bunch of pics then. My friend working on it says it should be on the street by then. Gary M.

We are in the process of connecting up the drive shaft. My trans is the LS-400 style with the big rubber driove ring on it. The Celica tunnel is about the same size as this ring. Less than 1/4 inch (6 mm) of clearance around it. With the very stiff motor mounts this may work, but it sure looks...

The 93 LS uses the ruber drivetrain coupling at the transmission output. My car (a 1983 Celica GT-S) uses a slip yoke. I know the A341 and 340 share many parts, and people on this list have changed out the output shaft to use the 341 in a 4X4 truck setup. My question is about a much easier thing...

Using the stock ECU virtually forces you to run the stock trans, ABS, traction control, and the transponder key system. Probably alot of other things as well. I am using an 1993 1UZ specifically because I wanted a much simpler wiring setup, and it is still alot to deal with. An aftermarket ECU...

Thanks for the reply, but LEX, the list moderator, already got me a pair of heads a while back, and my manifold is welded up. I hope to have pictures to post soon. It is a TIGHT!! fit, but we got it in there. The steering shaft has to be off while the manifold is slid back along the enigne, and...

I finallyhave some progress to report. The driver's side exhaust manifold is done. My friend did a beautiful job scullpting 2 peices of stainless steel tubing in between the 3rd and 4th portsof the manifold to move the collector out so that the pipe now gos around the outside of the steering...

The guy doing the welding for me wants a head to bolt up to for alignment/test fit. He is basically making a new driver's side exhaust manifold. The front 3 ports all stayed connected, but the 4th one had to be separated. He wants to bolt it on the head to tack it up, then weld it and re-check...

Just as the subject says, I need a 1UZ cylinder head. The driver's side exhaust manifold for my 83 1UZA65 Celica is almost done, but the rear most port had to be cut free from the others during fabrication. To weld it all back together, we would like a head to line it up on and make sure it all...

I don't know all the details as I have not done this myself, but I do know that several people are using recent GM ECU's to control the 1UZ engine. There is software available to reprogram several of the GM ECU's and they are quite well designed and able o run a wide variety of engines without...

You could probably use two MSD boxes with electronic rpm (mechanical like) advance curves. The two distributors are each even fire like a 4 banger, but they are times 90 degrees out from each other. So to separate crank triggers will be needed. For the MSD stuff you need 4 180 degree spaced...

Level 10 performance has a few different upgrade kits for the A340/341 transmissions. They have built several for twin turbo Supras. www.levelten.com/ Take a look. Gary M.

Just turned 39 Married 5 years 2 kids, daughter 3.5 and son 1.5 Own a house in so cal with a fair size 2 car garage. 3 cars total once my 83 1UZ Celica gets out here from Chicago. After it is running of course. Gary M.
