gorganl2000 Posted April 5, 2017 Author Share Posted April 5, 2017 (edited) anyone? ..i'm referring to the installation informaiton---like ring gapping, etc http://www.ukstarletowners.com/topic/52242-how-to-build-a-5e-fte-engine-5e-conversion/?hl=%2Bwossner+%2Bpiston+%2Bspecs i found a little on this tread, but not all Edited April 5, 2017 by gorganl2000 Quote Link to post Share on other sites
5e colin Posted April 5, 2017 Share Posted April 5, 2017 there not al going to be same each sheet if specked to a set of pistons get your machinist to measure them before he bores block he will bore each 1 then to the piston spec and mark the pistons Quote Link to post Share on other sites

AdamB Posted April 12, 2017 Share Posted April 12, 2017 I would expect a larger clearance on the first ring because it's closer to the piston crown, ie maximum heat and therefore would close up more under higher pressure and temperature.No harm in running the same clearance on both rings.

AdamB Posted April 14, 2017 Share Posted April 14, 2017 Clock the ring gaps 90 degrees apart.Follow that spec for ring gapUnsure on piston-cylinder clearance, this depends on what it's going to be used for, can run tighter if it's just a street motor, but something that's constantly at high rpm will require larger.

gorganl2000 Posted April 15, 2017 Author Share Posted April 15, 2017 seen specs online say 0.07mm which is about 0.0028" bore clearance Quote Link to post Share on other sites
