turbo: blow thru vs. draw thru

Wow. Have not seen that exhaust manifold in about 30 years. That is almost a unicorn. Nice find.

Rotomaster still sells service parts for that turbocharger. As long as the wheels are not damaged, it can simply be rebuilt. Not really difficult - some carbs are harder to rebuild. Here is the kit:

That intake adaptor should be fine on a dual plane intake. Can you post a picture of the bottom side of it?

The exhaust dump can be as small as 2.5 inches if it needs to be. You will probably need to make some room for that manifold on the passenger side of the early A body. I look under the hood of my '65 Barracuda and know I will have a hard time getting the exhaust upgraded. Can probably hammer a little clearance for that manifold, and sneak a 2.5 inch pipe out past the torsion.

Can you post a pic of the actuator on the exhaust?

The turbocharger needs a good oil drain. I recommend removing the mechanical fuel pump, and using that port to return the oil. Make sure the return line has at least 1/2" inside diameter all the way from the turbo to the block. Install an electric fuel pump at the tank.

What carb do you plan to use?
