well...i am going to put a Cold Air Intake on her. Probably go through and into the fender hole. but i have a pre 91 engine and i cant find any tech articles that tell me what to do in this situation...everyone wants them for dual plug systems...i feel lonely haha. so if you guys could point me in the right direction for that, it would be swell. also i am going to do an exhaust system...i was thinking going like 2.5 because 3 is too big for my four banger i think. Is the pacesetter a longtube or short? would it be just as good for my car to get the ranger header?i was also wondering about other upgrades (ie ignition, intake manifolds, etc, etc) what would be a)cost effective b) worthwhile for my car after exaust and intake. my two "brothers" have 5.0 mustangs and my other "brother" has a 305 camaro. whenever we go to the nearest city we always take their car because mine is embarassing and slow...please help me. Thanks guys!
