Formula Four Toyota #004 Rebuild

Got the opportunity to purchase a four seater Formula Toyota chassis from a good friend of mine (ColoradoToy91).

https://www.pirate4x4.com/forum/toyo...la4-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.

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 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

Very nice. That's going to be a great engine choice.

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.

Been working on this quite a bit just haven't uploaded any updates on it.

Went to KOH and got super motivated to get my buggy done.

Ordered some new front seats

Going to be a PITA to build a sheetmetal tunnel between the seats and the t-cases. Not a lot of clearance

Finally got the drivetrain mounted where the front seats will fit and the t-cases and tranny pushed up almost flat

Wanted to run full hydro but the budget isn't there so it's back to a steering box and hydro assist for now

This was as low as I could get the engine without hacking the stock frame rails. It looks high but it's almost 3" lower than how this engine would sit in a 5VZ swapped truck or 4Runner. Optical illusion since the buggy fender bars are really low on an FToy

Working on getting the radiator mounted and shroud built with the fan installed



This is the space I've got available to stick this thing

Building a 1" frame to hold the fan and shroud




Also started to try and figure out all the shifters and mounting locations. I think I'm going to end up ditching this factory auto shifter

Working on trying to get this thing wired. Trying to tie the factory 5VZ auto engine harness, the existing buggy harness and the stand alone harness all together




10 gal Jaz poly cell with a hydramat in it. Holley is damn proud of those hydramats for the price they charge for them. Hope it's a kickass pickup for this buggy



Also picked up some goodies for the buggy! Used set of 39" Red's and a rear D70 that's narrowed to the same width as an IFS rear axle (58"). Not sure if they will make it on the buggy this season but we'll see!
