I have a blaster that I bought motor was bulit by trenga raciing I wanted to replace the pistion& rings but can't seem to find it anywere its a 65.97 and no were to get a hold of trenga anymore any ideas? ???
i beleive you need to bore it to fit a 66mm by a machine shop. get a weisco piston
But the plated cylinder can pass off more heat so they're usually a performance upgrade.
Factory 7 sells the "Airsal" kits as a plated aluminum cylinder for racers. I believe lasxgames is running one. If you don't need the cylinder for racing, YFS101 may be correct and you should try to source a standard bore steel lined cylinder and have it ported (just to play on) and then send the aluminum cylinder out to have it bored and replated and sit it on the shelf as a spare/backup in case you ever go racing with your blaster.
