HAHA!
Cool. I bought a head for an OS RFB but I have yet to find an RFB! Normally people buy the right head for the motor but not me!
I'm kinda out of the R/C Diesel scene for now but I'm looking into getting a REAL Diesel car

VW Golf TDI or something like that.
Torque to spare and mileage to go with it (45Mpg easy) Talk about a good package!
