here is couple of pics of nord and TS flywheels ... i was very surprised when i find TS flywheel a lot lighter(my be 2-3 kilos) from nord wheel ..and also it can be made even lighter !!! look at the pics TS one is more dished in center and balast weight is concentrated at perifery..which is very easy for mashining

.... hmm cant attach pics .. will upload somewhere ..

in other pic u can see how bad is nord valve seat area ... midle part of valve seat is narower than port throat,and contacy face is very wide ..twice as neded

Jim Greek if u read here do you know can i radius cut existing seats at 46 angle and fit bigger valves(bmw M30 motors 46mm) or i must instal bmw seats both intake and exhaust(38mm bmw too

will bmw seats fit in stock nord valve seat nests?!@? or must be mashined to accept bigger seats ?and what about big vlave spark plug clearence

sorri for my language
