Hi guys I've only just registered as I'm usually browsing through the forums.. I have recently purchased a gt4z avenir w11 1999. Now the engine has had a seize and both head and block are unusable.now I know my turbo is incorrect being 14411-1e000. My cylinder head numbers are 53j2r.. haven't doing block numbers or I've forgotten what they were but anyway I went to a pick a part wreckers today as an exact gt4z w11 1999 is there. Lucky enough so was the motor - the turbo. i removed and taken block but noticed my cylinder head is low port.. the one at wreckers is a high port so I'm now unsure whether to go high port conversion if it is worth doing or what I was planning to do is get a de head and swap my valves cams etc.. what should I do ? Is my head I have now a det? Considering the factory det I believe is a high port?
