Well I got a set of 81.5mm B series pistons and Eagle H beam rods for my B series build. Did a compression calculator and it said it will sit at about 9.5:1 for the LS/Vtec. I have a guy that wants to buy the pistons for $410. I only paid $620 for both. I know for a little more I can get some higher compression pistons, but this is a daily driver so I'm not sure if I would be better of just staying with the lower cr.

 

Keep them and when you get to loving your car more it will be boost/nitrous able. But till then enjoy the great gas mileage.

 

buddy has the same combo in his ls/vtec runs 15psi al day long and gas mileage ain't that bad either. I think his comp is 9.3.1 some ---- like that

 

Well back again talkn bout ROSS pistons, on my former H23A VTEC I was running two years ago and it's been sitting ever since, I was using H22A rods with Custom Ross pistons,"Go ahead and say it cant be done cause of deck height BITCHASSCRACKER" but any whoo I had them custom made with the wrist pin located higher on the skirt so it would be feasable. Needless to say I went to the dyno and was having it tuned and at 22psi and a valve dropped"YEAH WITH FERRERA VTEC elimination cams and their valvetrain too" but last week I ran into one of our machinist at work and was talkn about how the piston is screwed and it is aluminum then he mentioned that we can TIG it back up and then mill it back down and if I have a good piston that he could take measurements and resurface the deck in the lathe and remachine the valve reliefs. Well he welded it back up CLEAN and next is the valve reliefs for tomorrow. SO if all works out well and it's true in shape and dimensions I"LL NEVER REBUY custom pistons if this guy will always be around"OH and its got to be weighed to make sure they are all in balance. If my cell phone would send the darn pics to my email I'll post them but waiting on verizon
