No luck boomer this is for theEcotec, not the e tec II. Ok rabbit, I need to thank u for your lead on the euro z16xer/18xer I first got the idea off one of ur posts. O dealt directly with John to get this through personal e mails, dude was cool. I took pics of the US-spec gasket and sent rhem to him with measurements, he e mailed me back his specs and after a month or so we traded info for the purchase. I ve also found Opel z series headers in Australia from Hurricane headers but tha Aussies didnt respond as well as John Ashley. Just for ****s and giggles in Greece the is a place called MGI Motorsport that has z16xer( Astra H) cams but they are over $900. Some Euro tuner in Germany,who I beleive has a vendor the US quotes their Ecu tunes for the 1.6 at 143the hp/ flywheel- something neither Trifecta or Jet will quote #s.
