Now that i have ur attention. I have a fully rebuilt Rb25 most of which has been modifed excluding the standard cams. im looking to achieve that 500hp figure. Most of everything has been dun to the motor, i kno its vague, but has any1 hit the 500 hp mark atw? what camshafts are adviseable if i don't want to modify anything else (ie cylinder head clearance machining, up-rated valve springs, special retainers, solid lifter kit)?
If it does hit 500hp atw ... u all will definitely be detailed
thanks
