I have a set of what I think are stock d-series pistons. Can anyone tell me what engine these came out of and what they will fit. I also need to know if the rod nuts on these pistons will work on my b18a1. I lost one rod nut and these are the only others I have. The b-series are 12 point and the d-series are six point. Will they be strong enough. Thanks

 

Bump, I need to get this baby back together soon. Thanks

 

Bump! Does anyone know anything about these? They must be some rare set of Mugen Pistons. For real peps, what the hell are these?

 

Bump! I really need an answer here.
