I have a 1988 Pontiac Fiero Formula, with a mostly stock L67 drivetrain from a 98 GTP. I will be dropping the cradle this winter to tear into the motor and do a gasket overhaul. While I have good access to the motor I am considering doing some modding. I currently have a FWI, Magnaflow catted 3" downpipe with 2.5" exhaust, colder plugs, 180 t stat, EGR and EVAP delete... in 2013 my car will be emissions exempt and I will probably be ditching the CAT and redoing the exhaust... I plan on getting a tune, not sure yet if I want to order a box tune, buy a tuner (no experience), or take it to a local shop to have it dyno tuned. I also want to run a VS cam from ZZP since they say it can be used with no other modifications, but I am not sure about this being true? Also I am considering headers, but am unsure if I will be able to use Speed Daddy's or some other cheaper ones without modifying them, but I also am unsure of how much running the stock manifolds is holding me back. I planned on going to a 3.4 pulley too. How does all this sound? Any input/suggestions/insight would be greatly appreciated!
