Im wanting to convert my bone stock 88 truck to full independent suspension using the rear assembly from a mkII supra for the sole purpose of (eventually) making it a wrx eater.

Im curious to what all needs done to put six lug hubs on a supra rearend and if the rearend is strong enough to handle rally driving.

Btw i know im crazy lol.

 

How much money is this project budgeted for??

I would guess the easiest way would be to have several CV axles Custom made.

Which would then adapting backing plates and brakes to work with your new axles.

Being they are not off the shelf and you will break them .

I had a person I know blew the rear out of us Supra about once a week.

I would bet there are none left within 100 miles.

Will it hold up Automatic?? Manual?? Engine??

There is always a weak link

 

Ive got a 22re 5sp manual 4x4 i was thinking about supra irs coverted to six lug and a 7mgte swap. I know the motor side of things i just need to know if anybody has tried this before.

 

And there is no budget, i only make around 10k a year (im in highschool) but idc if it takes me two years to build because of lack of funding. I should still have about five grand a year that can go to the build as long as my dd doesnt tear up.

 

Why hack a good truck for this? You want a "rally car" get a rally car.
On your budget your saying you can save 50% of your income? I made a little more than that when I was in high school and barely had enough for "weekend fun". Not saying it's impossible but it's not gunna be fun.

 

You need to just find a 4WD Tercel and start with that. 1) it's already a car. 2) you can get one cheap and 3) nobody swaps in IRS on a truck for a reason, and isn't because it's impossible.

 

don't listen to the haters

if you truly want irs, it's going to take a bunch of fab work: welding, cutting, grinding, etc

if it were me, i would just use the pickup driveline as-is, put in a big-ass engine, and throw a detroit, grizzly, or lsd in the rear for some traction. since these aren't all-wheel drive transfer cases, the front 4wd running gear just adds weight. either take it out or find a 2wd.

but that's just my suggestion. i would love to see pics if you decide one way or another

 

You could take a old car with ifs all the way around and do a body swap on to it. So it looks like a pickup. Just a suggestion. It just seems like a lot of work no matter how you go. I would just buy a used rally car for 7-10k when I can. That way when I back it in to a ditch or wall at the track I can find parts. Also if you plan on taking the rig to the track at all they might not let frankincar out for "insurance/safety" reasons. And if you have never driven on a track it's kinda RAD. Good luck hope this helps

 

Have RCV cryo some Porsche 930 CV's for you, it will help increase axle survival. And they can operate at a pretty decent angle.
contact Nate at Blazeland, he can probably offer some assistance.
getting the Toyota truck IFS front end to a low enough stance up front will be a challenge too. It is doable but a body swap on to an Audi Quatro might be a route to consider

People use Supra E-Brake calipers to convert truck rear end to disc brakes so getting a 6 lug rotor to work has got to be doable..

Have fun and document it well

 

I really appreciate the info guys, but i have decided against doing this because i dont have the cash to do something like this. I didnt really think about the supra suspension being completely different from the trucks front. It was more of a idea off the top of my head.

 

I would use a corvette IRS. Much stronger. But your big problem is track width. "Vettes are wider than your target vehicle.

I can envision your concept, but its going to be a monumental undertaking.

I would suggest more mechanical engineering into your idea before you invest money. Truth be told investing in yourself and a two year degree in college would serve you far better.

Get subscriptions to magazines dealing in hot rods. I know a bunch of people who build "hot rods" do use IRS systems for their rides. Yes; hot rods can be trucks too, and they are a cool interpretation. Learn all you can while you have the chance, time is fleeting.

Once you cut metal, money flows like water.

May I suggest a role model like Jacques Littlefield?

 

I do like your thinking outside the box on this.

It is an interesting idea but very much work

I thought about taking the front end of a Toyota 4x4 and stuffing it under the front of a Celica

I all ready have most all the parts and cars and trucks and even a 7mGTE but have way to many projects.

 

I only have a 5k per year budget so i think im gonna do an lsd, four link, and heavy sway bars to the straight axle i have and when i get more money, a 7mgte swap. It should handle almost as well as irs, plus itll be much easier and a little cheaper.

Thankyou so much for the ideas though. The vette rearend would be pretty cool, especially if i put widebody fenders and spacers in the front. Give a real fat stance. Plus, it would be stronger than the supra stuff.
