Not sure but i think the CL7 "R" is an on road engine so you'd probably be better off with the other one.

I think he meant CL7B Sti.
I have a Trinity Extech .21 EB Mod Pre Run and the Sirio CL7B Sti...both cranks snapped before the 1.5gal mark. The Trinity had some monster power and pulled really good. Killer bottom and transfered up to a strong top end. Sirio my friend and he wasnt impressed. I am in the process of putting the cranks back in them and will see how they run this time around...hoping for the best.
