Topic: 4.0 swap from jeep to '81 Toyota Truck

[n2osx]

I am able to get a motor auto trans and t case from a 4.0 xj really cheap and I am wondering if anyone has any info on this or has done a write up.

I'm shure the head shake must be becouse of the J e e p  thing right? The 4.0 is a great motor but it is a bit heavy for a toyota. Did jeep even offer a transfer case with a pass side drop? You arent gonna swap in those dana axles are you?
You might check around for a stand alone harness for a 4.0. I'm shure someone offers a harness for useing this motor in a buggy, or some other vehicle.

Don't want to see a sticker on it that reads "Built Toyota tuff with Jeep stuff"

I have seen pictures of a 4.0 swap into a 2nd gen Hilux, and you need to go measure how long that thing is. If the 4.0 is the inline 6 that I saw in the pictures, then it was so long that the guy had to remove the firewall of the Hilux and he never finished the project. I think he also cut out part of his radiator support and mounted the radiator in the bed or something crazy like that..........

Since you've got access to the engine, could you please measure from the front of the engine fan to the very rear of the cylinder head? Then compare that with a 22R.

Also, you are in even a worse situation than what I saw in the aforementioned pictures, since a 1st gen Hilux's engine bay is apprx. 1-3/4" shorter than a 2nd gen engine bay.

As for pound-per-power and/or displacement-per-power, I don't know how good the 4.0 is, but I've driven a couple of them and those motors kick butt on the streets when size/weight/efficiency is not an issue

Good luck

Definitely is a good motor, blingn has it in his xj, and that thing has plenty of power.  I thoukn the fit issues are gonna kill you though, that thing is big

Here is a buildup thread for you http://www.rockfrogs.org/phpBB2/viewtopic.php?t=156&start=0

He's a good friend of mine.  It's basically a Toyota frame and cab with a XJ front clip, 4.0 I-6, and Dana 44's front and rear.  It's got a flatbed so most of the weight is in the front.  That thing climbed everything in Moab!  It was amazing!
