Formula Four Toyota #004 Rebuild

[Volcom]

Got the opportunity to purchase a four seater Formula Toyota chassis from a good friend of mine. 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.

CO- Formula4 Build - Pirate4x4.Com : 4x4 and Off-Road Forum

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.

Going to suck building a buggy in a small 2 car garage with too much stuff in it already

This what it looked like right before he tore it down

The plan for this F-Toy is to swap in a 5VZ and auto from a junked 1996 4Runner I picked up in a trade. My dual ultimate crawler setup behind all that and run my Tacoma width TG Rock Assault front axle and IFS width TG Rock Assault rear axle.

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.

Looked good inside. Got a new timing belt, water pump, blah blah blah

This is wicked. Keep up the awesome work!

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.

Man one of my favorite 1st gen's is gone?!?!?
I get the whole long time with one project, one reason I moved on from my Trekker after 10 years.
Looking forward to see how your new build goes.

Was the 23 spline shaft in a T/C that ran a little low on gear oil? just asking because of the discoloration

which adapter did you use? i am using an inchworm I got from low range right before they were bought out by trail-gear and am using 21 spline stuff...because I am cheap and lazy and it came with a 23 to 21 spline adapter to use behind the A340H

TG coats them in some weird yellow crap. Probably so they don't rust on the boat ride here. Took some scrubbing to get it all off.

TG adapter. Acquired it for free.99 from a good friend of mine. Wasn't complete so I had to buy some stuff from TG to make it work. I didn't know they had a 23 to 21 spline adapter available, that would have been nice to know!

interesting on the coating.

i think Inchworm got the spline coupler adapter made though Advance Adapters.
Nice score on your adapter!
