Wondering what the parts needed are, who we get them from to swap in a 1998 3.4 into a 1988 4 runner.
If anyone can chime in great ! links to stores that supply needed parts.

most of the well organized info is on yotatech.
how much you need to buy depends on your skill level.


most of my swap stuff is in the first 12-15 pages here. 3.4 into my 89.

out with the old, in with the, well, old...

started the new truck project recently. scored an 89 runner off craigs for 500$ it was a 3.0 auto in its previous life. plans are the 3.4 V6, R150 5 speed an twin mini cases with 4.7s etc. like all good builds i skip past all the boring grinding stuff and spare any pics of the poor old IFS...

thinking it would be a lot of work and expense. Does putting a turbo on the original 3.0 make good sense ?

It is a lot of work and expense.

And less work and expense than trying to turbo a 3.0 and then doing the 3.4 when the 3.0 goes sideways

I recommend getting a running donor. That's what I did and it saved me a lot of money and parts searching. I salvaged as much as possible off the donor and parted out the rest. Parting it out pretty much paid for my swap as well as my dual cases and more.

The 3.0 had headgasket issues that you'd still be at risk for dealing with by adding a turbo. There's also not a ton of space so you'll likely be considering a rear mount, which can be a bit of work and expense.

The 3.4 bolts onto the stock motor mounts of the 3.0. Sourcing the parts is a bit time consuming, but I'll echo what is said here. Ideally you want the entire donor vehicle, but that means having a wreck in your driveway or garage. After that having a local junkyard willing to put the vehicle you're pulling from in a part of the junkyard that other people can't get to would be best.

From what I remember it took me a day to pull the old motor, and a day to put the new motor in. I bought the crossover pipe from toyota only swaps, and what I remember being the biggest pita was bolting the transmission to the motor, lots of swivels and lots of extensions. It took me a week or two doing the wiring, but again nothing too complicated and it fired up on the first try.

In terms of power, with a heavy chassie the power feels adequate. It's still definately not a speed demon, but you will go from 145 horsepower to roughly 190 horsepower. If that's not enough the 5vzfe also had trd supercharging possibilities, and the 5vzfe seems to tolerate boost alright. Also maintanance is SO MUCH easier on the 5vz compared to the 3vz. No more cap and rotors, and spark plugs are much easier.

Lots of good swap threads in the old yotatech forum. I did my swap basically solely based on the information there.
