Build 1990 4Runner Build/Rescue

That does "look" like it's sitting too high. The only 3.4 swap I've done is in my 2nd gen pickups. I made my own engine mount perches and used the OEM 3.4 rubber motor mounts so I don't know what to say about your 4Runner. I think I ended up with 4 degrees of tilt. Helps the rear drive line angle but hurts the front. Level is better IF you can do it. Ya gotta do what ya gotta do to make it fit.

How does the fan line up with your radiator? Clearance from the exhaust crossover to the firewall?

On my 88, I lowered the engine enough that I didn't need a body lift or cut the hood. When I put it in my 86, I had to raise it for steering linkage clearance so I had to cut my hood. Still wasn't as high as yours looks.

I'm in Tucson too and I use my heater. You must be tougher than I am. Good luck with it!

You realize that if you had a child born the day you started this thread, they'd be in 1st grade currently?

Glad to see it still trucking along

Man...when you put it that way this is just embarrassing! Time really does get away from ya sometimes...

Thanks for the help Scott! I think we've figured out where we went wrong - we didn't swap the engine mount brackets on the block over from the 3.0 to the 3.4. It took a bit of research to find out that the 3.4 ones are definitely not usable because they're angled differently than the 3.0 ones. Wishing we caught this before we got it installed...

When I did my swap, I got all my info on Yotatech. I was going from a 22RE and had no 3.0 parts to work with so I used what I had. I'm using the 3.4 engine brackets and the rubber mounts that were on my 99 4Runner donor. Home built frame side brackets.

Yeah, it sucks to catch stuff after you welded. I'm sure you'll get it worked out.

Also, I'm coming up on almost 5 years on my project so I can't razz you about your timeframe.

Motor mounts look OE, found a picture from my 3.0 parts runner and the riser on the frame is the old UCA mount. The hood interference is annoying but when I was planning out a 3.4 swap looked like guys were using the 3.0 motor mounts and doing a 3/8" to 1" body lift or doing cowl/hood scoop.

At least someone boxed in the frame mounts.. I'm a hack and never did on my SAS'd 4runner

Edit: Looked at the side profile picture again.. thats really high. What engine brackets are you using?

Well we figured out why the engine was sitting so high. We didn't swap the 3.0 brackets and mounts to the 3.4 before we put it in. Everybody said it was impossible to use the 3.4 mounts in the 3.0 frame, but we somehow accomplished that.

We tracked down our old mounts from the guy we gave our engine to and swapped them out and it sits much lower now.

Last night we spent some time getting the ORS conversion harness installed. Pretty easy install, just need to button up a few more things down by the transmission and that should be done.

As I was installing the OBD II port I came across his mess of wiring underneath the driver's side dash. It was so jumbled up that every time the clutch spring was pushed it moved the entire dash out. It was also installed in the worst way possible, with a bunch of old wire taps and even had two wires twisted and soldered together.

I was able to find the wiring diagram for this old thing so I got it removed, but unfortunately for us I think they cut into the original ignition harness which is going to be something I'll need to address prior to getting this thing started with the new motor.

Once we're done with wiring we'll start working on getting everything else plumbed and hooked up, but so far we're making pretty good progress.
