Just get one and sort out all the turbo inlet pipework/air filter adapter (but not the plug) so it fits in your own time at home then put the standard maf back on temporarily to drive it for mapping. Then when you get there just put the Z32 back on (which will be easy as you'll have sorted it all beforehand) then all you'll need Ed to do is chop your old plug off and solder the new one on ;-)Prob take me a weekend to sort this myself so i cant see myself doing it when i get to Ed.
What Mark said ^^^ if you spoke to Ed he'd probably advise the same.Just get one and sort out all the turbo inlet pipework/air filter adapter (but not the plug) so it fits in your own time at home then put the standard maf back on temporarily to drive it for mapping.
