Re: Slammed 1966 GMCummins 12v

Got everything back from powder coating again, I built the hot and cold side myself from 3” tubing. It was a tedious job but I got it done. Stuffed a intercooler in the front as well. With little grille modifications it fits perfectly behind there. I needed an external wastegate to give the little turbo a break at high RPM’s. It’s a 60mm precision gate that blows into the big turbo exhaust inlet. I’ve got no way of controlling max boost so a blow off valve or another wastegate might be in my future shopping cart at Summit. We will see…
