Id like to save some money over the summer and hopefully buy a used turbo sled for my last season before i head into the navy, and cant decide between a 4 stroke turbo or 2 stroke. Ive been doing alot of research on the 4 strokes and i like the fact that the engines on those yami's can go a VERY long time if built right. But the used 2-stroke turbo 's are usually a little bit cheaper and thats always a plus. I was wondering how long the engines last on the arctic cats with say a twisted race gas turbo kit running around 10-12lbs every weekend? Would i be doing rebuilds and fuel maintinence? Just looking for a basic rundown of how those arctic cat turbos hold up. Im a newbie on these engines with turbos so school me. I know there's been threads on this just looking for some new opinions. All replys will be greatly appreciated, Thanks.
