is there anything that i can get to up grade from my 92 prelude si (non vtec). i want to try and raise my rev limiter so if any one knows about a whole different ecu or just a chip then let me know. thanks

 

Upping your rev's on a stock h23a is a waste of money, you arent going to benifit from higher revs hardly at all AND keep in mind the h23a crank doesnt like high high revs. Chips are also a waste of money in my opinion, your best bet is to purchase an apexi s-afc and have it tuned on the dyno. If you do want a chip though, http://www.gude.com has chipped h23 ecu's.
