Volkswagen Kit Cars

Torsion housing stripped of all of the original drivetrain mounts (horns).

I am going to split it in the middle and make a square tube wrap around for the v6 to sit in.

This is the back of the square tube. The other 3 sides will be more like a c section welded to it.

It will also be the mount point for the new engine mounts.

The start of the fab work.

I cut the splines out of the tube, split it in two, and remounted the splines inside the tubes.

This wrap around will become a square tube.

The engine oil pan will sit in the notch in the middle of the torsion.

The springs will be the short type like a swing axle has. But will stick out the sides like a long spring IRS does.
 
I got the urethane bushings and mocked up the rear suspension. I could not get the alignment I wanted so it came back apart and got bent on a bit. Then all put back together for another mock up.

Good job.

I have a couple of questions I'm sure you thought of. Will there be any flex in the U frame as the wheels hit bumps causing them to pinch in toward each other? The engine mounts will add some stiffness but they're not solid, right? Also is the weight of the engine close to a VW? I was wondering about the strength of the torsion springs. I guess having it mid mount instead of it hanging off the back would make a big difference. I'm not being critical, just trying to learn something. Thanks.
 
Of course this is just the first major building block of the chassis.

There will be a whole lot more frame work and a good portion of it will be in the rear area. Such as above the trans between the shock towers. Not only just to simply tie together the chassis but to hold the trans, tank, battery, radiator and the whole back end of flip up body.

And.....

NONE of it even exist yet.
 
Sorry the pics are so bad.....time for a new phone.

The rear crossbar link that ties the shock towers and notch together.

Not a lot of parts made.

I have been doing a lot of figuring trying to get the kl flywheel and pressure plate into to Porsche bell housing.

But it really looks like I am going to have to make a flywheel and use a VW clutch.

I would really like to use the kl pressure plate and the fact that it is the same diameter as the VW bus (228mm) it would be capable.

It looks like the easiest way to go would be to get a stock replacement Porsche throw out bearing. A super heavy duty late VW 200mm plate and disc. Then make a flywheel.

I am just stick on wanting to use the larger diameter kl clutch....less spring more diameter.

The Porsche has a small (like a late beetle) but different mounting with and actual fork.

The VW trans off the mock up.

Of course the Porsche trans is the same bolt up....once I decide on clutch..

And I did decide to go with the Mazda pressure plate.

I have a Jetta TDI STD shift diesel starter coming. I think I can modify it to fit around the Mazda pressure plate.

Right now the plan is to thin down the Mazda flywheel so the clutch sticks out the right amount.

Then use a type 5 vw disc.

And a type 1 throw out bearing.

Modify the 901 fork .

Cut the starter ring off a vw type 1 flywheel and put it on the Mazda flywheel.

Then make an adapter for the Jetta starter. It has a long nose and the same bendix gear as a type 1. All to get the bendix to the right depth and reach around the Mazda pressure plate.
