I need some concrete info on a suitable turbo upgrade for a C1j running a standard cam and possibly in the future a Piper 285 if changing the cam would help the cause. Looking for over 200 bhp, car used daily, using for fast road, must spool up to full boost as close to a T2 as possible so no laggy crap etc.
Im after turbo specifications, ie wheels and housing sizes etc and not just a 'tomcat turbo will do'! Has anyone actually had one built to specification to truly suit the C1J or are the turbos all off the shelf / similar to what other cars use?
The reason i ask is i have been in some dreadfull boosting T25's, laggy and lifeless unless really revved hard. Really takes the fun away from driving a 5. Any ideas chaps??
