    1UZ vvti into a 4x4 1996 4Runner

    Did you supply 12 volts to the +BM terminal on the ecu? That powers the throttlebody.

    1UZ cooling system questions / issues

    My experience. My LS400 started slightly overheating when sitting in traffic and progressively got worse. Eventually the heater stopped blowing cold. I didn't loose any coolant or have any compression issue so I knew it couldn't be the head gasket. I pulled one heater hose while the motor was...

    1uz swap, bad ecu?

    E1 is ground. Check for continuity across E1 and the engine block first. The all ecu harness to engine grounds must be mounted.

    sc400 X-pipe and stock mufflers

    I'm running a 3uz in my 90 supra. My exhaust is 2.5" pipe with an x-pipe right after the trans. Then it transitions to a y-pipe just before the differential and a single pipe up to the 2.5" free flowing magnaflow muffler. Sounds really good but just a little raspy around 5k rpm. Might install...

    Non immobilized 1UZ VVTi, 3UZ ECUs

    Thanks for the information. Looks like I'll be changing out the knock sensor once I get closer to finishing. Might as well buy them new.

    Non immobilized 1UZ VVTi, 3UZ ECUs

    Yeah. I actually sent you a 3uz ecu to exchange for the bypassed 1uz ecu. I chose the 1uz ecu for two reasons. 1. The 3uz ecu would require me to install the electronic accelerator pedal in my car. I'm not a small guy and I hate squeezing myself under the dash. 2.The ls400 1uz vvti harness...

    Non immobilized 1UZ VVTi, 3UZ ECUs

    Hello George, You have another happy customer in the USA. I just got my UZ VVti motor running with your modified ecu. She started on the first try after I realized the throttle body needed 12 volts. I read one of the threads here where you helped a member out with...

    Non immobilized 1UZ VVTi, 3UZ ECUs

    George, I have an immobilser bypassed ecu I bought from you earlier this year. I'm close to start wiring it up but I'd like to know which wires , if any , I need to wire up on the grey plug that would originally power the key reader accessories. Thanks.

    1uz vvti into a Volga

    She sounds GREAT! I wish the laws here would allow me to do something similar. The police would ticket me everytime I drove it. We can't legally change the path of our exhaust from it's original design. My exhaust doesn't sound like a V8 to most people. Some have said it sounds like a huge...

    1uz vvti into a Volga

    LOL. You and I both know those welds suck but I'm learning. They aren't pretty but welding myself saves me a ton of money on my swaps/ projects. Here's a sound clip.

    1uz vvti into a Volga

    I did something similar on my 1992 toyota cressida. 2.25" pipe with x-pipe, two glasspacks and to dual in single out muffler. Sounds great!

    1984 - 1988 Toyota truck swap

    Yeah, it's a great motor and i am addicted to the 1uz. I also performed 1uz swaps into my 90 and 92 cressidas and a friend's 87 and 91 supras. I like the 1uz in the supra so much that I just bought a 91 supra to swap. It's a great motor for daily driving and get's great gas mileage in a...

    1984 - 1988 Toyota truck swap

    Here's my build thread. It's starts off with the turbo 22r swap and the 1uz swap begins on page 9. SC400 exhaust manifolds are a perfect fit. They are the only OEM manifold that will...

    New to the Lexus V8 Scene

    Welcome. The 1uz is not nearly as popular but it's very fun and fast in the right chassis. I completed my first swap in a 1990 cressida with the auto trans. I was very happy with the performance until I swap a 1uz/ w58 into a friends 1987 supra. Power to the wheels was much improved. There is no...
