That's the turbo on the right, the air cleaner on the left, and a side-draft marine application carburetor in-between. The chrome pipe coming out of the turbocharger feeds the intake charge to the two heads on opposite sides, and there was similar piping under the engine to get the exhaust from both sides up to the turbocharger. |
Neat powertrain. Never worked on one of those.
Agree with Richard that it wasn't much better by the eighties. Early '80s Pontiac Trans Am (2nd generation body style) went to a small GM V8 with a turbo, as all the large V8s were cut. Throttle lag was similar to a ship with an engine room telegraph.
