Wow, that looks pretty damn sweet! I wish I had the know-how and equipment to make my own EFI turbo setup...but there's nothing wrong with a carb'd turbo slant. I'm keeping an eye on this project! Keep up the good work brotha!

With the fabrication finally done on the intake manifold and plenum It's ready to seal up. A quick tally comes up with about 8 feet of weld bead in this thing. You can bet there are at least a couple of places where some porosity in a weld would create a vacuum leak. I could figure out a way to pressure test it and grind/re-weld whatever turns up. Instead I decided to coat the inside with some epoxy I got from Caswell. I gave it 2 coats. The second coat went on nice and thick.

Looks like your close to getting it fired up. Looks good!

How well does that epoxy stick to the shiny aluminum? The thought of it flaking loose makes me cringe. I would have high temp powder coated the outside

Well... the block, crank, head, etc. are still at the machine shop.

But, yeah, not that far away from hanging the turbo and manifold on the old stock motor that is still in the truck.

I etched it with POR15 metal prep. So it should stick all right. I've even used this particular stuff on the inside of polyethylene motorcycle tanks. Nothing sticks to those - except this Caswell epoxy.

I made a bad mistake and learned something new.

Ha ha... those 2 things go together don't they?

So I welded all those pipe thread bungs into the plenum for various things that will have to plug into them. I had some nice brass plugs that I put in the holes then I submerged the whole thing in a bucket of etching solution. Well the solution wicked into the threads and jammed all the brass plugs in all the threaded holes. I had to drill all 6 of those suckers out. No, it was not the epoxy. I could see the evidence of corrosion on the remains of the threads.

It's all good now. The plugs are drilled out and the holes have been re-tapped. But I didn't need to cause myself an extra couple hours of work.

Very cool look of that intake!!
The combination with stock runners and your own design plenum,
and the colour... Kawasaki green?


Thomas

The place I had to cut the exhaust manifold to retain the divider didn't put the turbo quite where it needed to be so I fabricated and extension to move the turbo out and up. The extension is also divided to keep the exhaust pulses separated going into the divided turbine housing.


Hey Thomas, Rustoleum calls it Grabber Green but it is pretty close Kawasaki.

So... It's going in the Vette, right

Lookin' good!

Well, it's not going in that Vette but possibly in a slightly newer C4 if I can find the right deal.

The Vette in the background is motivated by a GMC 6.5 diesel with a big turbo and a cranked up injection pump.

Here's a write-up of the Diesel Corvette build

Today I worked on additional mock-up stuff. Re-shaped the dipstick tube.
Since I will temporarily run i a draw through on the one barrel carb I fabbed up an intake to mount the carb to the turbo.


EDIT: I've decided I'm not going to do this. Not even for test running

A little more intake plumbing done.
