Draw through slant six turbo setup

Hey Brandon! I like your Dart Sport, I have a 73 Dart Sport, I finally got that out and driving well this past summer and put 1500+ miles on it, it was a blast.

To answer your question, this turbo does not have the proper carbon seal for draw through use, I will be buying the matching Buick turbo that does from the guy I got the 4 barrel Buick pre-turbo carb manifold from. For now though, it works very well!

It does suck about a quart of oil through the turbo into the engine every 300 miles, I am fine with that until I find a proper turbo for draw through, or revert to fuel injection as I plan to in the future. I have 5 other vehicles to drive, and access to my dad's Dodge Ram if mine has a sudden problem, so this build does not have to be perfect yet. But dang, am I learning lots doing it!

When the truck sits after being driven for awhile, some excess oil sits in the compressor housing and emits a "mosquito fog" for the first 5 seconds or so. It does not smoke while running though, and the seal I believe is actually functioning under boost, as pressure is against the seal. It does not have a dreaded throttle lag like I was told it would have.

To answer your other questions, the manifold for the carburetor I got from a swap meet(the guy had the turbo for my manifold, but I did not but that since I already had a turbo, I should have bought it, but since I know the guy, I plan to buy it and a complete one with the carb, manifold and turbo as well), it was made for a q-jet. I got an aluminum Mr. Gasket spacer to adapt it to the square bore, it needed height for the wide AFB throttle shafts to clear the plenum exit anyways. The manifold was from a 1980 Buick T-type I believe. It has coolant running through it to heat the carb base. Time will tell if it will be enough for the brisk winters here in MN.

I am running an in-line electric fuel pump, bypassed the mechanical fuel pump, and will be removing the old pump completely.
