before you do anything more. get full length subframes and longtubes with an o/r h-pipe or x-pipe...that way you can have a nicer (and louder) exhaust note along with the added power and not twist up your car in the meantime while you save more money for: the stock lower and stock maf is the bottle neck...after you free those up look to your heads as the meak link

imo spending the money on a supercharger before upgrading your engine is wasted money

just seen that your car is an 87. maybe a maf conversion should be on your list

I have equal shorty's on my car and sparkplugs aren't bad at all. Nothing compared to my V8 S10. And my buddy has longtubes with an x-pipe and he's lowered and doesn't have anyproblems. Infact I scrape my catback flanges more then he does his collectors.
