Well thats strange because ive had my cossy lump at 300bhp+ for five years now and i dont recall it blowing up....come to think of it ive had to replace head gasket and turbo in those five thrashed years thats not bad if you ask me....and ive always thought atmo cossy lumps as strange why why why do something to an engine that was designed to be turbo,d no disrespect intended to the atmo crew
