dont waste your money on a walboro...get a denso supra pump...im on my 3rd walboro in the last year year since i had the swap done...theyre peices of *** lol...im just waiting for this one to go out already so i have an excuse to buy a denso
oh and 250 whp is MAD easy to make...im putting down 195.6 with a FMIC, air filter, and no cat on 10 psi and 100 octane...and that was on my stock pump with messed up timing (we fixed the timing pulls WAY harder now)...so yah...250 is an easily obtainable goal especially with yer list of mods
