aldo56 0 Posted June 29, 2006 okay so far i have leaned a fair amount about putting an xu10 head onto a 1.6 gti: the xu10 has a better flow rate however the exhaust valves are restrictive the inlet ports must be matched to the inlet manifold the head must be skimmed by around 1mm a xu9 gasket can be used however some overhang will occur a gti-6 gasket can also be used?? I just really want to know if this is all right and if any performance gains will be made. i have made extensive searches and much of the reading is very confusing and contradictory but the above is what i have made out from it. i will only be using the car for road use and so the fully blown race engine argument need not enter this post! cheers allan Share this post Link to post Share on other sites
Anthony 1,003 Posted June 29, 2006 I wouldn't use an XU9 (83mm) gasket, as you'll likely burn out the fire ring as they'll stick into the combustion chamber. You need an XU10 (86mm) gasket of sorts. Share this post Link to post Share on other sites
Miles 331 1 Cars Posted June 29, 2006 I would say the complete Opposite and use a std 1.6 or 1.9 gasket, But what ever way you do it it's not going to seat as the std head and liners But then again I would stick with the normal head myself after experancing a 1.9 with this on.
