Good idea Dum-Dum. I will get the clamp and hacksaw out and have a go. I did look into tapping a 1/8th NPT thread but I seem to remember I couldn't find a "straight" answer as to what drill size to use even though loads of threads on enthusiast type car forums came up.
Right, just gone and cut the adapter down, took about 60% off but then realised it wasn't threaded all the way down, now it looks like I will have to get that 1/8th NPT tap afterall
Or just get it welded and waste the £6 odd quid that I spent on the poxy adapter? 
This is the kind of thing that ends up making these kinds of projects cost a fapping fortune!
No it's not but it's off a Vauxhall which is owned by GM and it's off a Z20NET engine if that means anything to you? I have no idea how the serial numbers work or anything.
Edit: Umm, Dum, what did you type in to find those cheap 1/8th NPT taps on eGay? Because I have just searched "1/8th NPT tap" on eGay and the cheapest is about £15 if you include delivery from the US?
That's a lot of money wasted on one thing:
M12x1.5 taps: £9 quid
M12x1.5 to 1/8NPT adapter: £6 quid 84 p
£15 quid wasted on fitting the EGT gauge and counting!
