I'm looking into purchasing a custom piston set for my L28, but thought I'd ask for any advice ya'll might have for me before I consider purchasing something like this. My goal for this project is a 14/15:1 compression ratio, for running e85. Engine setup would be carburetted n42/n47, overbore 3mm (89mm), stock l28 rods, stock crank, and hopefully a metal head gasket that's about 1mm. I was looking at some Wiseco pistons that had a 9cc dome, and those about fit the bill, just can't find them to purchase anywhere. A 9cc dome also sounds kind of rediculous, i havn't done much research into those but i think that those might protrude the gasket.
Anyone else done something like this? Any advice would be golden.
