Formula Four Toyota #004 Rebuild
« on: Dec 23, 2019, 05:58:12 AM »
Got the opportunity to purchase a four seater Formula Toyota chassis from a good friend of mine (ColoradoToy91). 

https://www.pirate4x4.com/forum/toyota-formula-toy-forum/1030496-co-formula4-build.html
He took his engine, transmission, t-case, and axles from this F-Toy and is in the process of moving it into a Rock Lizard chassis.

I've been wheeling a 1984 Toyota 4Runner for the last 15 years.  Started the build in 2004.  Typical 1st gen 4Runner build with Toyota axles.  I've been wheeling with buddies with buggies the last 5-6 years and being full bodied has been tough.  Especially tough on drivetrain parts.  Had my fair share of broken R&P's and twisted t-case outputs.

I haven't babied this 4Runner at all.  Its been wheeled everywhere in Colorado, Moab UT, South Dakota, and the Hammers.

Decided to sell the 4Runner to a good friend of mine.  Part of the deal was I kept the axles and t-cases.  Those will be transplanted into the F-Toy.

The 4Runner ran before I pulled the engine but it ran poorly.  Tons of white smoke out of the tail pipe.  Figured it had a blown HG.  Pulled the engine apart and got the heads off it.  HG didn't seem to have any signs of a HG failure.  Decided to have the heads pressure tested and they were both cracked internally. 

Picked up another 3.4 from a 99 Tacoma with 180K on it.  This motor had a manual 5 speed behind it.

Had to pull the t-cases apart to get the stock 21 spline input in the front reduction block out.  Going behind an auto, it has to be upgraded to 23 spline.

Joe built some factory style motor mounts for his project and couldn't end up using them.  They worked perfectly for my F-Toy

Engine is in!  Pushed back as far as I could.

Got the t-cases mounted to the transmission and figuring out how to flat belly this thing.

It's tucked up above the bottom of the frame rails.  Only thing sticking down is the drain plug.
