I'm curious if anyone has opinions or experience with either Enginetech or Evergreen pistons as an 1g OE replacement? I'm looking for a set for my 1g/6bolt turbo engine with stock fuel trims. I know there's other options out there like Topline, NPR/Nippon, and Silv-O-Lite. I've not heard good things about Topline (broken ring land and porous material seem common), available NPRs seem to be 2g specific, and Silv-O-Lite I have no data. I'm reusing my 1g rods but my machinist won't machine them to 22mm so that limits my options. I could take the rods elsewhere but not my first choice. I want to try to stick with 21mm pin if possible.
Here's a list of the 1g 6 bolt part numbers I've come up with:
