Superrunner Updates - Stoffregen Motorsports

[Stoffregen Motorsports]

I know some of you have seen the white 1st gen 4Runner I built a few years ago. Harry Wagner applied the name Superrunner, and it stuck. It's basically an all out hunting rig, or so that's what the owner calls it. 4.0L V6 power (2006 Tundra 1GR-FE), 6spd manual trans, Diamond axle 3 link front, Tacoma axle full float rear, heavy body mod/fender cut, lots of bells and whistles.

It's back in my shop for some updates and I thought I'd share some of the work with you all.

We started off the updating with a Heavy Flywheel from LC Engineering. The V6 is torquey enough, but the added flywheel weight smooths out the low end. Perfect for crawling or going slow while modulating the brakes.





Replacing the FJ80 drive plates on the rear full float axle with Diamond Axle's setup was basic, but I had to replace a broken drive pin first.





The landing pad on the front lower control arms was not large enough to hit the air bumps, so those were widened, then the LCA's were re-powder coated and installed. We also coated the springs in a monochromatic black color scheme to match the new black preload adjusters.

Some convenience items were on the list too. Relocate the e-locker activating switches, replace with modern rocker switches, relocate the lighting switches forward of where they were (for less cramped access), install a triple stick shifter on the t-cases, build a new tunnel to keep out the noise/fumes/weather, add a console on top of that to beautify the whole thing. We're also going to have a custom shifter boot combo made for us by our local upholstery shop, after the console gets back from powder coating.

Starting with a bathc of new Carling switches from OTRATTW (The Switch Guys), it was time to find new locations for them.



Here is where the lighting switches were (notice the switch labeled "IR"? That's infrared, mounted on the front bumper. You use it with night vision goggles.



The locker switches were located under the stereo, not an easy access location, so I moved them to the left of the steering column and housed them in a Carling three switch pod. While I was at it, I had the switch guys make a custom labeled switch to replace the "clutch start cancel" switch.



And to terminate them, I used Packard connectors and Carling connector housings, for easy removal.

Two USB charging ports were added. One inside the custom armrest (for cell phone), one under the stereo. New panels/mounts had to be made for both.

Cans of worms are present in any job. We decided to clean up some of the in-dash wiring while I had the dash out. Boy, the hours really rack up when you open that can...

The owner of the truck really wanted A-pillar mounted grab handles. If you've ever had the opportunity to remove the skins on a 1st gen 4Runner, you'll know that such provisions are not available. I made some simple weld in brackets and plug welded the hell out of them. The handles were sourced from a FJ80 and simply screw in on top of the re-applied factory skins (after drilling holes of course).

Up next: triple stick and new console.

Nice!

How far down are the bump pads on the arm? That looks like it would bend the arms really bad if you hit hard enough. Its better (if space allows) to bump off the actual axle rather than the arm, this keeps you from bending the arm/heim or shearing the bolts.

The grab handles came out really clean.

What is the infrared switch for?

Awesome, great seeing your posts again.

Nice ride! Love seeing your work. And seeing the first gens getting some love. Wanna dig into my dash?

I do have to agree, id think the bumps would bend the heck outta that control. arm. Maybe its double sleeved?

Thanks everyone. It's hard to find the time to post on everything, but when I get enough pics on something relevant, I do like to share.

The bumps could be in a better spot, I agree. It is not my design. I built the truck in 2009 using a 3 link kit that the owner had already purchased. As a matter of fact, when he dropped it off this last time, I asked him if we could re-do the front suspension. He declined my offer, but I'll keep trying! We have made changes to the system already, like 4 years ago when we lowered the ride height 4 inches and cut the body, but I would like to make additional improvements.

I will say that the shocks do take the "hard-stop" before any bending of the control arm would happen, that's when the axle is articulated. If he jumped it (which I hope to God he does not), on a level surface, then yes, the air bumps become the hard stop.

Infrared switch is for an infrared light on the front bumper. When using night vision goggles, and the IR light, it's clear as day. We bought a locking switch from the switch guys for the IR light because it could cause damage to someones eyes, if they looked right into it. The locking switch is a basic safety feature.

That's cheating... isn't it? lol

I really enjoy your build threads, the craftsmanship is exemplary!
