1UZFE Swap humble beginings.
I finally decided on an engine to replace my tired 3vze a few days ago. After doing 1-2 months of research, cost effectiveness, and generally figuring out what was best suited for me, I came to the conclusion that the 1uzfe was the one for me.
My current setup is a 3vze in front of an a340h auto trans. **EDIT**I have sold the manual trans setup as plans have changed and the auto is staying in the truck.
**EDIT**The engine and trans choices have changed due to time and preference. The engine that is being used is a 95 OBD1 and the trans is staying as an a340H.
I'm thinking of possibly having mounts CNC'ed so that it will fit the stock mounting to 1uz (3vze to 1uz), if I do I will be keeping the CAD file and sharing for others future projects. ** EDIT **I will be using something very similar to Toyminator's engine mount but will probably as said have them CNC'ed.
Looks like I'm going to get this project done for less than 2 grand (unless I run into issues).
Can't wait to get it done and I will document with pictures as much as I can!

In. Want to see this one go down. And I am so jealous that you could find a 97 LS400 for so cheap. That is the only year I want to put into my truck and legally can put in my truck.
Plus, want to see how the manual conversion goes.

Officially starting today!!!!!
Got the 1uz out of the car, ordered a few new parts for it and will be starting the electronics research this weekend. Hopefully have some pictures after tonight.

Awesome! What will be interesting is doing the swap from OBD I to OBD II and dealing with the immobilizer. If you have the keys though, I think you will be fine. Just have to tuck the box/transponder away under the dash.

Also, I would do your engine mounts like toyminator did. Smartest and most efficient way to do it. You will have to get the SC400 mounts though and some generic RX7 poly bushings. But you will be able to adjust the height of the engine if you follow his pattern.

This thread was probably the most help on figuring out what wires to connect to the existing wire harness in my 4runner. Some of the wiring will be different, but most of the basic power connections should be the same.

And this one is good for just getting the engine running out of the car.

I sold the 97 picked up a 95 Engine/Harness/ECU/Ignitor (SC400).
I decided the OBD2 was going to cause unnecessary amounts of work and probably a ton of headaches.
I pulled the intake manifold off today for the first time and TON of carbon build up on the back side of the throttle body and in the runners, so I decided to pull the plugs just to check and sure enough the plugs were showing signs of running super rich leading me to believe that the previous owner had been riding on an SEL / CEL for a while due to bad 02 sensors.
The engine turns fine and hopefully in a few days I can get a compression test done.
I would upload the pictures I have but I'm working on my truck at my dads house and left my phone in his garage =(.

Parts needed so far:
- Flex plate (decided to stay auto for now)
- MAFS / AFM (not sure what Toyota calls it)
- Tundra headers 00-04
- LS oil pan (the 95 is an SC)
- Timing belt

Engine ready to tear the heads off after a comp test to replace head gaskets, valve seals, check the hone on the cylinders and possibly re-ring (if need be) amongst a few other things.

Toyminator your more than welcome to chime in, this is a first for me and I could use all the help I can get.
I do have a few questions about fitment and installation.
Because I'm using the a340h with the 1uz bell housing am I going to have to build a new trans cross member or is it something I can just move back?
Secondly, I'm not sure I understand why I have to use the traction control. Is there no way to isolate a signal and loop it so the engine doesn't require it to actually be hooked up or installed?
I have read I can use the 3vze stock radiator, is this true (It's brand new is why I ask.)
Do the 00-04 Tundra headers need to be shorty's or long headers?

This is how I did mine.
I used the larger bushings.

You possibly have a link to this setup?

Don't need the traction control.
The 3vz radiator may work but I'd keep an eye on the temps. It just doesn't hold anywhere near the amount of fluid that the Lexus radiator does.
Here's my mounts.

At least I was on the right track with the mounts, glad to know you don't need the TCS, and thanks for the info on the cross member.
I was very skeptical about using the 1uz mounts. I like the urethane block style for 2 reasons; Near solid and smaller / can be made smaller.
Thanks for the reply.

Sorry I didn't jump in and was tardy. But yeah, both Toy & 89 got yer back.
I also saw a transmission cross member adapter that basically was a thick plate that you bolt to the transmission where the cross member mounts and it "extends" the mounting area which then bolts to the existing cross member.
EDIT: Is there any reason why you aren't going to use the 1uz transmission?

I think the 1uz trans is bad. I didn't need it since I was planning on going with a manual trans but I've become spoiled with this auto trans (First one I have ever owned).

Yes, that is the bracket! I read that the guy who makes that is the former owner/partner of Downey Offroad. That might work for you and is dirt cheap.
