i have a prelude 92 S....base model.....i think i'm gonna replace the engine in another 50K miles. is it possible to drop in an H23 (si engine) and put Si parts on it? how about an H22 A w a vtec head? any idea on how much doing all that **** costs? this car is just temporary for the next few years until i get a new one. but for now i want it to be a decent car....so far i only have an AEM CAI on it. Also, on the AEM is i had to grind teh hole for the intake tube to go thru. Is it ok for the rubber sock of the filter to be slightly touching the metal hole? the metal is bent and not sharp. Just need advice =). Just got into preludes a few months ago.
