Re: Need more power!!
Ti valves let you run lighter springs which is their real advantage so add springs and retainers to that if you want to see any power improvement.
Certainly not worth the bang-to-buck expense unless you have a heavily worked engine.
Do Erion list their piston weights?
The 954 OEM pistons are _very_ light already.
