sportwerks v2 .21.........any good?

[pwnzor]

I can get a brand new one, HT pipe, clutch setup and air filter for $140 shipped............Rocco, I know you have experience with these. Tell me what you think about them, the price is really good. Will it be enough for club level racing? What kind of power characteristics are to be expected, what plugs do the like? Do they need shimmed to run 30% out of box? What kind of longeivity can I expect if treated halfway decent thnaks for any info guys
