Question ECORS Stock Class build - TTB Bronco

I've been wanting to do some racing and have a "go fast" trail rig for those fire roading trips.

I thought about building a Ranger or a Toyota, but my ol FSB seems like a sold choice. I mean HELL, it already has "Baja" style bumpers All tube work is and will be 1.75"x.120 DOM (might get some .095 wall for interior tubes.

Specs:
89 Bronco 103K miles
351W efi
C6
BW1356
D44 TTB front
8.8 rear (have 9" to replace it)




My plans initally:

Suspension: remote resi 2.5" FOX shocks at all 4 corners, some 2" lift springs for the front, stock springs in the rear wtih traction bars.

Drivetrain: fix leaks/exhaust on the motor, trans is fine, BIG cooler for trans, new u-joints throughout, modify front shafts for full circle clips, open front diff, 9" swap in rear with discs and spool.

Interior: Corbeau XPs and 5 points, plus fire extinguishers, safety equip, etc.

My main debate on starting the rig is what I want to do with the body.
Debating doing a full tube rig with rear radiator like Davids "Lil Digger"


Or maybe save some time and $ on mounting steering/pedals/shifters/gauges/wiring etc and build a "firewall buggy", mostly tube, but stock firewall/dash/controls like my 4runner


My last option is just doin an interior cage and removing doors/glass/tailgate.
^ I'm kinda leaning toward this just for simplicity, but I'd really like to cut the weight of the sheet metal and make the "body" smaller with one of the above options...

I think I can get this thing read to race for around $5-6K. The $1600 in shocks is a pretty big hit on that budget...

Any thoughts on this? am I fuckin up somewhere? will I be competitive?(assuming i can figure out that "driving" part...)

Oh, and does anyone wanna sponsor me? I could always use welding wire or beer

I like the idea of stripping it, gutting it, and cage. Keep the look of a bronco, but shed as much weight as possible. Glad to see so many people taking interest in ECORS.

That's probably what I'll end up doing. I guess we'll see as I get it stripped down.

The body has some cracks and rust in it.

I'll drive it over the the gravel pit and weigh it. Then we'll see how much I can trim this pig down.

Here's an idea from the cheap buggy thread, I wouldn't mind doing something like this with a Bronco myself.

I'm now in the Parts Gathering stage.

Things I need/looking for sponsorship/support on are:

-285/75-16 or 305/70-16 tires, any tread/wear, I'm sure I'll need plenty of spares

-Headers/exhaust

-Ford 9" ARB?

- Disc brakes for 9"

-Trans cooler

-fire extinguisher mounts

-Race radios

-Spare driveshafts

-Seats

-Harnesses

I'll run stickers, banners, T shirts whatever! Even paint it on the side of my house if I get some good stuff!

So far JAX INC "America's Finest Industrial Lubricants" www.jax.com are providing all fluids/greases/aerosols fo the build.

Get your spot today on the NHFF ECORS Stock Bronco.

Here is what is going on the hood:


It's my "shop" logo, basically where me and all my wheelin buddies hang out and build our junk. Not a shop for hire...

I've got a 9" spool I'd sell on the cheap... Better plan on beefing up that TTB! We don't have any TTB rigs in A right now. I think a well designed one could do really well. Biggest downfall would be vehicle size. A lot of the tracks seem to favor the smaller rigs. My early Bronco feels too big at times. Keep it coming!

A few weight saving hints, firstskin all the front panels so thatits just the outer skin (you will need a frame of sorts underneath to support it, I built mine into a one piece tilt front clip). Eliminate the rad support, put the rad in the back (built a shield out of sheet metal to shield yourself and direct airflow). Then gut the doors (windows and all) and rear bed sides. Also get rid of the dash and everything else inside the cab. All said this should drop around 5-800 lbs on your rig (I have an 80 f-250 down to 4500lbs and its sitting on a d60& sterling 10.25).

I'll be running cutting brakes in teh rear now after going to the WindRock race. I think the TTB will be fine, I'm going to do a bit of gusseting on some important mounts. (the Boobie Ranger is TTB btw). It will no doubt be a beast in the woods, but the size will help keep people from passing me

Full interior gutting, glass removal, and door removal is going to happen.

I don't know that moving the radiator to the back is a big deal... none of the other A classers I saw/know have rear radiators.

I'm really hoping to get this one under 4000lbs, race ready (spare, tools, oba, jack).

Whats up TBItoy? 4000 pounds is do-able I think. Especially if you run a dough-nut spare. But as you know thats only good to 55mph! Lol all joking aside I'm looking forward to the buildup. Lets go weigh that beast and see where we are starting from.

good luck on the 4k weight goal. 1983 bronco (Brad Carrier's username on NC4x4) raced a TTB FSB and it fell apart on him. You might want to get up with him for some ideas. He is now racing a YJ. check out gofastbroncos.com if you haven't already. there is a LOT of good info on that site for a TTB'd rig.

Forgot about the boobie truck. I was thinking full size stuff.

Oh, and the #156 XJ has a rear mounted rad. I was thinking of doing this on my EB, but it was because of the limited size due to the narrow frame rails. Ended up not doing it and knock on wood, I've had no issues running a 302 w/a $175 alum Griffin rad. It is really small. About 20x22". Your rig could fit a honkin' big rad up front. Cooling shouldn't be an issue.

4000lbs is more than doable on a 1/2 ton rated bronco, like i said i have a reg. cab long box stripped to 4500lbs and you have the advantage of the lighter auto and tcase.

THe rad relocation is morefor weight, the core supports on these trucks are heavy.

Well, I have a 351w/C6/BW1356 so it's got the "big" drivetrain. The frame is significantly smaller on the bronco than the 250/350 trucks though.


I'm going to run the stock 33 gal fuel tank, a full size spare, and a rear winch, so I should have plenty of rear ballast.

I MAY consider the rear mount radiator... but I really don't feel like I'd be gaining much in weight savings We'll see after I get it stripped down.

IIRC core support is about 150-200 lbs, does the truck have an aluminum rad already?

Yep, aluminum radiator w/ plastic tanks, but I've got another rad/fan setup that I may run.

well, the bronco decided its own fate...


SO, the body got the AX




I got the wiring harness cut down to just engine function, and proceeded to crank the engine and spray transmission fluid all over myself :dumbass:

The engine is on the stand to get some freshening and resealing.
The trans is going to a local guy to build.
and I got everything pressure washed and cleaned up.

Its sitting in the shop waiting on me to get back from Milwaukee...

Co dog wasn't much help, but she was happy to get a new winter bed

I'll be watching this one closely. I've been wanting to do basically the same thing for a while now, I've always thought these broncos would make a great all around fun rig (after the body is trimmed down, or ditched all together). I think this thing would be sweet with early bronco skins on a full cage But I guess that would probably go over budget.

I am required by class rules to run a stock appearing hood and grille.

Hood will be narrowed to just the "center" part of the hood that is the width of the grill.

If I ever deciede to fully skin it, i'll use Ranger 'glass fenders/doorskins probably...
