"How much supra can you put into a truck?" build

[87mk111]

Dood this is pretty sweet. I've wnated to try something like this but don't have the time, money, or space to do it.

hate the tails, I would have used late model tacoma taillights, but otherwise, looks good!

Thanks for the input. I agree. When I did the tails, it was just a bagged custom truck and I was looking to do something that no one had done before(in 2005). Now it is just an eye-sore on a vehicle that is otherwise all toyota. I don't have any current plans on dealing with that as it would distract me from getting it drivable. We'll see what happens down the road.

To make sense, here it was before...

One of my favorites.

that's hilarious

Looking Good! Maybe one day I'll quit being a slacker and finish the one I'm doing.

You should have seen the look on the owner's face when I asked if I could put my truck under his.

Very nice. Are you going to modify the rear fenders so you can fit really wide tires under the fenders (since you'll have very little weight on them), say 315's??? I love your ambition, and the work done so far seems pretty awesome. Definitely subscribed.

That is a great question that I hadn't thought to ask for opinions because I assumed the obvious. I had two options in mind. Initially I had thought to run 15x7 front and 15x10 in rear. I already bought the street tires and rims to fit. Cragar soft 8: 4 inch backspace. I later decided that I really love the MK4 tt wheels and want those on the truck instead. The 15x10 on the back would give it a dually look, or muscle car. But the tt's will stay true to the supra theme and performance. At the moment I am leaning towards the tt rims, but can't afford them as I have a long way to go. I would run sawblades until I can get them. Whatever I chose will likely be permanent because I only want to do body work once. I hate doing body work. What is yalls input. Not really looking for any other options though.

You can always have the MKIV TT rims widened so they still retain the look. With the lack of weight in the rear, you're going to need some serious beefy tires. You could always run the TT rims with 285's in the rear, and just swap them out for slicks when you go to the track. Look in my build thread, in the recent posts, for a cheap upgrade on your traction bars.

Cool project, perhaps bellcranks and mount the shocks horizontal would have kept the tray usable?

That would require a lot of ingenuity. I can only get as far as design, and calculations, but I don't have the building skills to implement that setup. I have thought about it, but decided the extra work wasn't worth it. I feel dumb saying that to a guy with a turbo 6l build in a supra. Props on that btw.

Thanks for the reminder on the traction bars. That was a concern of mine when I saw the bars on my pearl supra were bent. I have extras that I was going to reinforce, i just need to remember to do that.

My number 1 concern about this build is traction. Has anyone finished one of these with the supra suspension on the rear? I am hoping that will make up the traction that every supratruck desperately needs along with a good tire choice. I think for now the suck will just have to run sawblades until I can get my hands on TT's. If anyone has some for a good price...

 

[honestabe]

BTW, the traction arm reinforcing I did was because Flateric did it first and told me about it. He says it works great, even with 500 RWHP. Just be sure to get new poly bushings.

I have an update on the project, but first I have a couple of better pics from last weekend I forgot about... They show the engine a little better.

Here are pics of the progress from today. I have started grafting 2 fenders together to get longer fenders. The pass side was done first and decided to do the driver side a little different so that it would be easier. Much less time was spent on the driver side. This is early work on the body. There is much more to do so it looks crappy right now. But I want to show how it is going to look.

 

[honestabe]

Looks really good bro. I like the idea of extending the front end.

 

[suprahilux]

Thanks. I think it is a little easier than rebuilding the firewall.

Stretching the nose came about with the position of the subrame according to the engine position.

I have to get a driveshaft made eventually. Steel or aluminum. and why?

aluminium ones because they handle power better than steel ones and they have a better critical speed rating.

Do some googling and you'll find guys who are dragging big blocks who all justify the extra expense of an aluminium shaft not because of performance gains but because of the insurance that having an aluminium shaft gives them against failure.

Apparently 99% of shaft failures happen on the big end of the strip where they approach the critical speed. Aluminium shaft have a much higher critical speed and also are designed to give just a little along their entire length rather than be "stiff" and un forgiving which eventually leads to catastrophic failure. It also has been noted that if failure occurs anyone would rather have an aluminium fail becuase then far less damage to the vehicle is sustained.

The best shaft is a carbon shaft because when it fails it simply turns into cloth under the car and has almost no risk of damaging anything.

I remembered doing this research when I was buying my alu driveshaft and just rechecked to be sure, but there ya go. Everything indicateds you infact want the aluminium shaft in higher power applications, not a steel one.

 

[suprahilux]

Thanks honestabe. That is what I was looking for. So it is critical velocity that destroys. I thought it was torque. But I guess with any upgraded ds that souldn't be a problem.
Now I need to find out who will make me an aluminum supra driveshaft that is longer. Not yet sure how much longer. I haven't measured yet. I just know it is longer than the supra and shorter than the pickup.
