Well, this is a BAD idea. For one, the turbo is attached directly to
the manifold, so where would you put it? But that's not the problem.
Remember the `79-80 Turbo Stangs and Capris? They were the carbed turbo
models. It had a draw through turbo system and mounted the turbo under the
intake. A pipe ran from the exhaust manifold, under the engine, and up to
the turbo. In that pipe, they put a converter. Now, the problem was, too
much heat. The converter was notorious for burning up an breaking down.
The turbo always got killed when chunks of converter were sucked into the
impeller. Also, it slowed down the exhaust and caused even more lag. Point
is, a very high flow converter after the turbo is the only way to get max
power and keeps the sniffer happy.
