ok i have an 84 318i and want to put a rear mount turbo setup in the trunk or under the rear end... the problem i am facing is that there is no room underneith the car to route the turbo/ intercooler piping. can i route the pipes through the interior without sacrificing passenger capacity? :screwy: and if so, which would be the best way to set everything up so that the inside of the car wont get super hot??? any help would be appreciated.

So you want to cut up the interior and run the piping through the inside of the car without sacrificing interior space?

Why not just run a standard turbo setup? A custom job like this would not be cost-bennifit productive. A regular turbo kit would be much better and more feasible.

And considering how hot that air is gonna get...running any of that piping through the car is gonna make near everything hot as hell.
