Hellbug are no more, so you can't buy this kit anymore!! The turbo sits on the left hand side of the tranny, and the inlet plumbing comes up through a hole in the firewall, across the firewall in the car and then out through another hole into the engine bay and into the carb (weber 32/34 DMTT).
Here is another shot showing the exhaust mount. The exhaust runs down beside the rocker cover and across the rear valvance. The turbo muffler is not shown but above you can see the tailpipe that mounts to the exhaust on the right hand side
Next up if the oil feed to the turbo. This comes from an adapter that screws into the oil pressure switch, and is a hard line back to the turbo. The return comes out underneath and returns via a line back to the rocker cover (with a pipe welded into it).
