I'm rebuilding the 6-bolt for my 1g and I'm going with 2g pistons, 1g rods. The car is going to be a daily driver and I'm looking to run 20psi daily and up to 30 at the track. The rings are Hastings Piston Rings (I ordered the combo from DSM Graveyard). What piston-to-wall clearance and rind end gaps should I be running?
 
Well, I called DSM Graveyard and they weren't really 100% sure. I'd imagine I would just run the stock 2g PTW clearance since they're cast iron and don't really expand like Aftermarket pistons do, does that make sense? What's stock 2g PTW? .0012 - .0020?
 
with it being turbo I would look for .002-.0025 on the P2W and about .020-.022 on the top ring and .022-.024 on the 2nd ring

but that is me, I tend to build my engines a tad loose, and live every so often with a cold morn rattle or a wisp of blue smoke now n then but they tend to live.
