I'm looking to buy pistons and rings in +.40mm. Preferably in the flat top variation. There seems to be a worldwide shortage of some kind. Please point me in the direction of some +.40 flat tops for the l28. 280zx or 280z since they're the same block, just as long as its flat top.
I'm rebuilding my first L28 (first engine as well) and recently got my block back from the shop. The cylinders have been freshly bored and I'm installing new pistons with new rings. I'm following the book recommended on here (How to Rebuild your Nissan & Datsun OHC Engine Manual).
