Turbo related upgrades (94 S4)

[Dwayne Cosby <dccosby@interlog.com>]

I spent the weekend at Mosport at a BMW driving school. My instructor is
the owner of a major tuning shop in the Toronto area (Mantis Racing). He
suggests that the car (94 S4) could be made much more responsive by
porting and polishing the exhaust manifold (cheap about US$200),
installing a bigger turbo intake impellor, blueprinting the turbo, and
removing the exhaust resonator. 

Any comments? I've been considering a port and polish job on the stock
manifold for a while now.
