you think that it'll cost how much to get 300hp in a prelude? are you talking NA or with boost?
you should meet with tony baker (preludepower.com name: tonybaker12), he's down in Florida with a 300+HP daily driver 3rd gen:
here's his dyno without the zex shot:

It does pretty good, and that was off the bottle.
