has anyone hear of a sts setup

[occasional demons]

i should be one of the first to have a rear turbo mount on a 4 banger car.

I guess you'll have to change that to " i will be one of the few to have a rear turbo mount on a 4 banger car.

But it should sound unique, as the engine noises won't be as close to mask the sound of it spooling.
That's what I miss about the early 1980's turbos, they definitly could be heard.
