Engine swap 3.6 for 4.7

I have a 2001 tundra with 4.7 blown engine. Found wrecked 2002 tundra with 3.6 v6. Trying to install 3.6 into 2001 but motor mounts on frame don't match. Anybody know where I can get swap engine mounts to match 3.6 to 4.7?

 

You talking about the 3.4 (5vz-fe)?

 

Yeah 3.4 v6

 

Toyota use different mounts than the 4.7 vs 3.4 if my memory is right.

mounts can be had junk yard or dealer or parts store.

 

The mounts welded to the frame are different so I need some adapters to mate the V6 to the frame either the V8 mounts.

 

Honestly you might have to fab something up to do it. Conversion in our trucks are rare anymore unless you go pre 1995.

Why don't you save the headache and pita and just drop other 4.7 in.

 

I think you may be right. I could cut the V8 mounts off and weld the V6 mounts in place, but I am leaning toward rebuilding the 4.7 or finding a used one. I think the trannys are the same for the 3.4 and 4.7 so hopefully I could use the 3.4 tranny I have now with only 150K miles on it.

 

If the engine is out and on the stand I would rebuild the 4.7. long as the block is good. Off the heads to a machine shop for leak down test..

What was the failure of the engine to begin with?

 

Timing belt broke. Since it is an interference engine I will have to pull the heads to see how much damage was done. Engine has 270K on it. Found a used 4.7 with 109K for $1100 so I may go with that.

 

Ouch.. bend valves I bet but sometimes you get lucky at times I would check it.

1100 is not bad I would rebuild the front end, seals, water pump and all timing components. That way you saved a headache down the line.

 

Good advice -- thanks for your help Mike.

 

Glad I could help.

 

I'm doing something similar but a cab sawp do I use the wiring in the dash from the v6 cab on the v8 cab note doing a manual conversion aswell so I'm kinda stuck on the wireing because the dash wiring from the cab that was a v8 model has more connections for the automatic like the ignition speedometer etc
Unlike the wiring harness in the dash for the v6

 

Welcome!
You might have a hard time getting a response on a 5 y/o thread.

@empty_lord or @Tundra2 might have a bit of advice if you ask super duper nice.

 

This is an interesting, and complex problem to my eyes. It's unfortunately, completely out of my wheelhouse. I am no help here.

I'll definitely be following to learn though.

 

Ok so the 3.4L with the 5 speed 01 tundra was in a
Rollover. So the donor cab is the same year cab but has had the 4.7L with the automatic tranny so thus I am doing a cab sawp and a manual conversion which includes cutting out mounting points for the clutch master cylinder and parking brake in the fire wall also cutting a section out the floor for the tranny and T-case shifters as well as swapping the steering column so the interior wiring harness was swapped around and because the 4.7 interior wiring harness didn't have the clutch cancel start wired and the speedometer has 5 connections while the 3.4 interior wiring harness has 4 to the speedometer so I was trying to figure out if I could use the 4.7 interior wiring harness but to be safe and from looking on 1st gen fourms I decided to use the 3.4 interior wiring harness in the donor cab

 

Would you happen to have a few pictures of your cross member? I’m doing a 5 speed swap in my 3.4 and needing a few things to reference
