Monkeywrenchracing.com sells the pistions, rods, not titanium valves but black nitrated, some of the strongest valves you can buy, and stiffer valve springs if you like to rev your motor. The spark plugs depends on how much nitrous you want to run
I am running a 50 shot of nitrous express. the wet kit. I have ran about 2 1/2 bottles already, with my stock plugs. But now my car idles at like 600rpm and it is missing randomly at idle. I can't figure it out so I am going to start with plugs, then try a valve job, then check pistons and rings. Sound good?
