Prodrive Non-turbo Exhasut on a Turbo
Bought a 2.0 Sport Prodrive backbox by mistake. Will it fit my turbo? Will it work or will my engine blow it to smithereens?
Thanks

API Dave said to me that the Prodrive b.b. designed for a turbo Impreza is a restrictive beast... So by that rationale I'd expect the NA jobbie to fair even worse on a turbo car!! It prob has an inlet pipe of less than 2.5" dia., right?
Get rid, and get something more suitable and freer flowing IMHO...

Don't know about flow rates of the exhausts, but it should physically fit ok.. Seem to remember people have fitted turbo exhausts to non turbo cars, so should work the other way ?

Not sure what size exhaust the sport has, think the Impreza turbo was 2.25 inches and the Prodrive exhaust was 2.5 inches with a 3 (or 3.5) inch back box, so it could be different (looks slightly different too 
)
As for being restrictive, no not really, if your pushing 270bhp its ok, if your pushing 300bhp it will be restrictive, but as UK cars were hitting the limit at around 270bhp it wasnt bad, and it didnt kill your ear drums

Seems to line up ok, it is a straight through so there are no split pipes inside and is 2.5" bore like the rest of my system, will wait until the gasket arrives before having a go!
