stprasinz Posted September 29, 2007 Share Posted September 29, 2007 87mm bore and only 91mm headgasket other than stock.... Any one know anywhere to get a hg other than the 91 mm bore, I found everywhere from Courtesy Nissan to Motorsports. But what about me I have a 1mm over bore... That is a lot of area to create detonation when using a 2mm hg... Any clues... Bore it to 91 mm and drop in some forged right lol.... Seriously.. I figured I'd buy a metal hg with at worst an 89mm bore........But oh no..... So now I'm stuck with a felpro...... Anyone got the hook up?

HizAndHerz Posted September 29, 2007 Share Posted September 29, 2007 What's wrong with Felpro? Have you had problems with them or are you just wanting to go all metal? Quote Link to comment Share on other sites More sharing options...
stprasinz Posted September 29, 2007 Author Share Posted September 29, 2007 Well I'm running 24 psi of boost. I don't know if the fuel I got was the cause of the hg failure or not My hg only lasted 2,000 miles... And when the gasket poped I was only running 20psi... The night before i made like 8-10 1/8 mile passes at 24.. So I figured the metal hg would have cured the problem.... And then I'd probably be looking at a whole in my psiton right now... So I don't know I'll probably just slap the felpro in there... I'll just have to be happy at lower boost for daily use... Quote Link to comment Share on other sites More sharing options...
