I just bought a freshly built short block that contained internals that I don't plan on taking advantage of... thus, they are for sale. I am willing to sell together or separate. The pistons were installed but since the engine was never finished, the rings are unused as well. Wiseco piston # K541M815 I have these posted on another forum and received a few PM's asking about compression on the pistons. I cannot tell you that. I can tell you that Wiseco lists them as 8.3-8.6 for an LS and 8.6-8.9 for a b18c .. BUT.. that doesn't mean anything! You need to do the math for your particular setup. Here is the link to the Wiseco info on the piston: http://www.wiseco.com/PDFs/Catalogs/SC08/AcuraHonda.pdf ** RODS ARE SOLD ** $350 shipped for the pistons alone A few things I'd be interested in if you wanted to trade: Ported LS head Upgraded LS valve train Aftermarket LS cams B series adjustable cam gears Basically.. performance stuff for the top end of an LS I know I'm a noob on here.. but I have plenty of vouches on other forums.. I run the semi-popular Michigan forum Xceedspeed.com and have more than enough people who can vouch for the fact that I'm trustworthy. On to the pictures!!
