are you a stock k20? Reason i ask is stage 2 cams doesn't make that much HP on a stock compression k20. Sure you see graphs 240whp or so but they're all UNCORRECTED
. Corrected its around 230-235whp ish. You will gain more HP by porting the head, more compression or M5 race gas.
But to answer your question: to achieve your HP numbers and you have a spending limit i would look into skunk2 cams. They go for $300-400 used VS the competitors. If you're iffy about the cams (which you shouldn't be bc i run them) then you should look for a set of used Prayoonto's, Brian Crowers. Those are the cams that sell relatively cheap but not as cheap as Skunk2. Then with the remaining money you have i would get bigger injectors and run E85 or M5 race gas and that Should put you where you want to be HP wise..
Drag cartels hold their value and i really haven't seen them sell under $800-750. If they do sell around there its because they really want them sold in my opinion lol.
, i'm thinking of just putting my rsx on the bottle and a retune
What's wrong with Skunk2?
Because they don't actually run skunk2 cams, they just read what they see and spread lies and don't experience the issues themselves...
