91 3FE to 2UZ Swap (3 Viewers)

Fuel Lines....

To test fire the engine, I basically ran soft lines from the engine to the tank.....

Zach kept giving me chit to take those out and do hardlines... It was the right call, I definitely like this setup mucho betta!!

First red circle are the soft lines I ran.... the next 2 are the hardlines I added....

New Lines, I did shorten the line close to the brake booster....

The lines run all the way down the firewall to the factory lines to the tank:

Good call Zach! Fuel lines... re-Done!

Started putting back on the front end.... Its finally starting to look like a truck again!

Fan & Radiator clears just fine!!

Nice work!!

Nice work. Looking forward to seeing it at the meeting.

Nice work. You might want to consider putting a bead on the fuel line tubing to prevent them from slipping off. I use this tool by Graham. Made in the USA.

Is you 2uz connected to a 5sp auto? If so, I have some kits that might interest you. I believe they would both work with the 2UZ , but there aren't many swaps to try it on!

80 1HDFTE + 5sp Auto with factory shifter

I made some parts to adapt the factory 80 series shifter to an A750 auto. I didn't like the bulky center consoles and floor cutting associated with putting the 100 series shifter in an 80. I can put this kit together on a case by case basis right now, just can't act me at Sales@LutzAuto.com if...

1hdfte swap to 80 late ECU dash lights

I recently swapped a 1HDFTE into an 80 series. Most of the dash lights can be wire straight to the cluster, but on the late model 1HDFTE ECUs, the cruise light and auto trans 2nd start and pwr light signals are only over multiplex. I made a circuit board with a microcontroller that reads the...

I finally got the 80 out of Zachs shop!! Thanks for working with me on all the delays...

I got a few PMs on what my plans were for the exhaust so I'll post it...

My plan was to try to keep everything inside the frame rails and use parts I already had in my parts pile...

The exhaust is a a single cat I cut out from the LX parts truck and the stock 3fe muffler...

2uz 80 on 37s...

Looks like you have some cutting to do, or big bump stops ?

Yep... that'll be next to get suspension squared away... drivetrain clearances/flexing/etc...

Super excited for you to see this thing nearing completion!

When you get the chance, can you post up some detail around:
- Air intake tubing
- what lower radiator hose you used
- transmission crossmember (did I miss this?)

Thanks!

Thanks, much appreciated...

The Air Intake took a minute to figure out... I spent more time than I'd like to admit getting this together... I hacked up a number of boxes, plastics, couplers etc...

Right from the start, I knew I couldn't fit the "box" or "square" air filter in the 2uz into the 80. There isn't enough space with the battery box there.

SO I stuck with the 80 round filter (I kinda like it better)...

Zach also tossed in a tid bit to change the top hat to a 1fz style.. It can be cut down to a round interface vs the 3fe square interface... The boxes are the same, just easier to adapt...

I started hacking up all pieces in my parts pile... 3fe intakes, LX intakes, anything 3" ish hose related and started piecing things together...

In the end here's my final setup:

The back side of the vacuum lines routing.. that also took a minute to get right..

The lower radiator hose was easy... the LX470/100 hose is a fit to the 3FE radiator... I did have to do a slight trim but it worked...

For the crossmember, thats all @Zjohnsonua fab.... Used the existing crossmember mount/bolting here it is... I love it!

The 80 air box is a really good design and excellent at keeping water out of the intake. JMHO

I'm right there with you. It's embarrassing to think how much time I've spent researching how best to do this. Why couldn't you have posted this months ago? I'd probably have mine on the road by now.

On the older style (pre 95) airbox lids you can cut the square “elbow” off and place a flange round the round hole that remains and do this:

Yep! That was going to be my initial plan.. I had seen that done...

Although when I was able to pickup a 1FZ top for free... I ran with it...
