on the other hand, one of my friends rs's had an sti turbo/intercooler, headers, (and a bunch of other stuff), and after tuning he had about 300 hp at 7 psi of boost with really quick spool-up and good torque. i have definitely heard of people blowing motors like this though, and it is always better to have a turbo on a car that was meant to have one from the factory. if you do go the turbo kit route you should definitely get a standalone engine management system, which are usually about $1500 say if you got the hydra.
What did your friend with the boosted rs do about tuning specifically? What EM did he do and what all did he change fuel system wise, if he's ever told you
