I'm about to buy a sts motor in a couple of days.
I like both the d21b& the d21t.I like d21t more due to the material of the piston. Also the work done on the crank and sleeve.My question is,if i get
the d21t with a standard plug head button, not a turbo head,will it preform
better than the d21b.
I just dont want to deal with turbo plugs,they are expencive.
