Based on where the wiring terminals are I think it's already got a mini-starter on it - it's completely covered with a thermal blanket and tucked inside the headers so I can't really tell :p
I was looking at it closer last night to see if there is any hope of lifting the engine with the headers unbolted to get to the starter, and decided the correct tool for removing the headers is a reciprocating saw and a wrench or two.
