it uses the new shape typhoon lump (air cooled hi-per 2 200mm disk) same as a newish runner with no waterpump basicly so it can be machined for a wc conversion or used as a cross over with an eleci waterpump. easy disk conversion too. good strong engine and rarely crack (providing you dont go mental with the tranny cover bolts) btw.. NEVER use ali coloured bolts for your tranny case. just humbrol them...
nah they fur up and corrode in within hours. :nerd: some tosser that had mine did it. got them out eventually
plus the fact your tranny cover is the main strength in your engine. they crack when you use weak bolts (or only use 2 as alot of people do)
never can judge SRs very well, i would guess about £600 - 800 depending on who wants one at the time mine was £175 off egay
