Block is at the machine shop getting bored and honed to 81.25mm, just wondering what people out there like for pistons? I'm looking to do a mild N/A build, 200HP at crank after I'm done. Looking at P30 or P73 Pistons (can get OEM ITR .25 over from Acura for $36 each not including rings). Anyone like RS Machine or NPR stuff?? Or should I stick with OEM?? Also, are there differences in piston rings from b16 (a/b), b17, b18c1/5?? I once heard all b-series vtec rings were the same even though Honda has different part numbers. Let me know, thanks.
