1992 FJ80 6.0 Vortec Engine Swap

Me too
We're not set on the engine setup yet... we might do a little something to push for some extra horses...

You'd be amazed what a cam and a good tune would do...

Why not Turbo or Supercharge it?
Onur told me there are people in the middle east getting 800hp with turbo. That should be enough power for you and keeping the rig more original.

A 800hp 1fz-fe is not a motor I would want to live with every day. More expensive and less reliable than a GM Gen III V8.

That and you couldn't get the automatic transmission to hold the power so you would need to do a manual swap with an H151. The limit for the auto seems to be around 550 estimated crank hp.

I would settle for 300-400 on mine!!

300-400 is easy.

Let's do it!!! Show me the way!!!

For a DIY'er check out lilevo's thread his truck makes around 400 crank hp. I would go with a slightly smaller turbo but all the parts and methods are there for someone to follow. I did the same idea but went for a little more power in my thread

I've been on the fence about adding boost to my 6L because it is pretty damn fast as it is.. Adding 6-8# of boost with some good injectors and a tune would probably put me @ 600hp easily.

Well my dear friends...

Finally some good news

I just got back from Steelnutz with some updates... The transmission and the transfer case are in!! whoohoo!!!

Now we are having a minor issue with the clearance of the driveshaft vs the transmission pan... not a big deal...

I am posting some pictures of the installation completed since I was not able to take some shots of the process.

We are waiting for new FJ80 motor mounts and we will be checking for clearance of the oil pan before getting the engine in... we will decide what is gonna be done to the engine this weekend

I am pretty happy about the process so far... I know is just the beginning, but it feels good to have the ball rolling again...

I will keep posting some more stuff during this month...

Roger out!

Stoked for you. Please keep posting pics of the process and note any surprises. I would like a ride when you are done (since we are neighbors). Cheers, J

What motor mounts did you guys decide on?

We're using some custom mounts from R&B

Try using a longer slip on the driveshaft and flipping it so the slip end is on the T-case side.

Thank you for the info... We will give it another try on Friday...

Or just use an earlier pan that is more shallow and filter

Out of a 1990s perhaps?

Also, any particular camshaft that you guys would recommend?
