if youve read my previous post, i was wondering what all the engines were like. im mainly trying to learn, but im also curious because i want to upgrade/swap out my 12A, but i dont know with what yet. any ideas on how to squeeze a few more HP outta my Rex would be nice. btw its an 85 GSL, i was hoping for something faster than my dads car he has a stock GSL-SE that beats me everytime...i wanna win for once, im starting to feel like a loser oh well...thanks anyway

 

you can do a lot with the 12a engine. putting a hi flow exaust is one of them. i can give you a list of thing to do. i'llgonna send you a pm.
