dapiper Posted May 24, 2006 Share Posted May 24, 2006 HKS said not to go smaller than 89 mm bore due to possible gasket damage. Not sure why. Were you at ZDayZ? Quote Link to comment Share on other sites More sharing options...
racerx260 Posted May 24, 2006 Author Share Posted May 24, 2006 Thanks for the info, I will only be at 87 . thats a .40 overbore. Guess i'll run a stock head gasket.Is the motorsport metal gasket the same? I was at the meet at the dragon but had to work fri and sat, I came in sun morn and only saw a couple of early cars. 2003z with his green car with the cool flairs and the two cars that got second in early z for stock and mod.I think I saw 240hoke leaving on my way in.Everybody else probably left saturday.
