I was thinking about buying these because I want to turbocharge the n/a I will be putting into my 510, I wont be doing the the rebuild until sometime next year but this looks like a screaming deal for low compression rotors. What do you think? Do rotors have milled surfaces that could not be withing spec? or be milled to far? what should I check before buying these? thanks

 

uhmm... look for a warranty? (seems like good advice to me) (maybe a return policy too? )

 

You will need the counter weight also, then have the whle assembly balanced..

 

how much do counterwieghts usually go for? I was just wondering if there was any machining done on the rotor that might cause problems for example if I was to buy used heads for a piston engine but they have been milled to many times it would cause a problem same with rotors?

 

You're not supposed to mill rotors... maybe he did, and that's why he's selling them

 

good point

 

just what exactly do you think race clearancing the rotors involves?????

MILLING THEM

 

what part do they mill to race clearance? also they are probably milled to fit the bigger 3mm apex seals right? I am not sure what that entales but they must make room somewhere
