Z31 Rebuild. VG30ET guru's needed
 

I recently started a restoration of a VG30ET motor for a pathfinder build and as a long ago member of the ORG I know there are members here far smarter than the other nissan related forums out there. I'm looking at capedcadaver, matt93se, and greeny to name a few.

The motor had low compression when I got it (motor was free) and upon teardown I found that 3 cyclinars have ringland failure. Everything thing else measures out fine but the bores need to be re bored at least 20 over. The problem I am finding is sourcing new pistons. Nissan doesn't have them and several ebay searches yield really old replacements that are not the W series floating wrist pins that I need.

??Z32 pistions:gotme:?? everyone tells me something different and before I had over $800+ dollars I need to be sure on them.

Any other sources, vendor's whatever will be appreciated

Rock auto has floating pin pistons but only stock bore, no over bore sizes. The brand is EngineTech. Maybe if you contacted EngineTech directly, you might get what you need.
