steve260z Posted March 2, 2011 Share Posted March 2, 2011 I'm putting together my stroker. L28 with a P90 and 240sx pistons. (KA24s if I remember correctly) In assembling the block the piston rose above the block by .6mm. As described here: http://www.geocities.com/inlinestroker/index.htm (Actually a typo on that page. States .06mm but should be .6mm) I had the pistons ground down approx .7mm. So that leaves a deck height of .1mm textbook. In measuring each install piston it averages .12 deck height. Coupled with my .8mm metal head gasket that give me a quench of approx. .92mm or .036 inches. Searching the web regarding the correct amount of Quench provides varying recommended distances between the head and piston. One post on hybrid z stated anything over .035" is too much and other engine building sites talk about running up to .05"... Suggestions anyone?
