  • B3 rebuild questions.

    Well, long story short, my Festy's stock engine is shot. ('93, EFI) Hooked the compression tester up to her, 60-120-0-120, valve cover gasket blew out, oil in the intake... Anyway, I'm trying to fix the car as cheap as possible, so unless someone would be willing to donate a fresh B3 or B6, I'm going to rebuild the one I have. This isn't my first engine build, so I'm not completely green, however, does anyone have torque and clearance specifications for the B3 engine? Specifically looking for piston ring gap and main/rod bearing clearances.

    Switch to the Miata rods and use the B6 torque specs, which are everywhere. don't have bearing clearances over .0018". Gap your top ring to .007, 2nd to .008.
    No car too fast !

      What's the advantage of Miata rods?
