    I find it amazing how far and detailed these have become in the last few years. Bravo!

    Quick question. Would the 1uzfe off of a Lexus GS400 fit in the '87 as well as from the sc400 or is it harder?

    A great idea for another sub section that was kind of touched on in the write-up is things that change/different things needed depending on what the 1UZ comes out of.

    you can grab other uz engines, but the sc400 has all the parts you will need unless you plan on doing a remote oil filter setup, a custom oil pan, custom headers, ect. The ls400 1uz will need all of these plus the harness will be more work to use.

    Sorry for the late reply, man. I've been off the grid for a while. The 1UZ off a GS400 is the VVTi version. You can use it but you'd have to get a rear sump oil pan assembly from an SC400, and I believe the oil filter housing will have to be changed as well. Your biggest problem is going to be the factory computer; it has an immobilizer, plus it uses signals from the automatic transmission and I don't know if anyone has ever managed a manual swap on a VVTi 1UZ. If you plan on running VVTi, I suggest you skip the bullshit and go straight to a standalone which will allow you to use multiple valve timing profiles like the Megasquirt 3X.

    Edit: I updated the write-up with some more pictures and a few more details. I have a lot of extra information to add in, and I'll do so when I have the time.

    I just finished the mechanical part of a vvti gs400 swap. you WILL need the oil filter neck also. The immobilizer isn't a big deal anymore as it's been hacked and you can purchase one with this already done from GeorgeR on lextreme.com for around 250$. He basically replaces the security chip right on the ECU!! with one one that completely and flawlessly bypasses the security.
    I've done ms3 with the expansion on a vvti 1uz and it's not easy and takes a lot of tinkering to get the vvti to work at all. I eventually got frustrated with the amount of time it took to do anything and sold the entire setup. Then got a ls1 and called it a day.

    We're still waiting to see how the ecu behaves without the automatic transmission. I suspect we will have to find some way to trick the ecu into thinking the solenoids are still there.
