dont get a F20b engine... there will be to many things to worry about. for example what if a gasket blows or something.... how would you get the parts for it? you cant just go to your local parts store and ask for a part for a F20b engine b/c we dont have that engine in the US. i know some parts probably are interchangable but why go through all that trouble.. just get an H22 its the most logical way to go. or if you really got some money how about the CL Type S 6 Speed motor?? now that would be really nice and different.... have 260hp at the fly is pretty nice....
just my .02 worth......
