Datsun Roadster Parts from Rallye Enterprises, Ltd.


NOTE: Style of oil ring varies



When ordering 1600 rings, you need to know that there are two ring configurations that could be in your engine. They difference is in the ring thickness.


Type A: dome pistons have these
First (Top) Ring is .075" (2mm)
Second Ring is .100" thick (2.5mm)
Third Ring is .150 thick (4mm)

Type B: (typically on flatops, but not always, check yours before ordering)
First and Second Ring are same thickness .075" (2mm)
Third Ring is .150 thick (4mm)

CHECK WITH YOUR MACHINE SHOP BEFORE ORDERING RINGS AS THEY CANNOT BE RETURNED. "Unopened" or Opened. It is extremely easy to damage rings by improper installation on or removal from a piston. Would YOU like to be the next buyer of a set that has been improperly handled and that won't peform as expected? I think not...
