I'll measure it for you when I go down the shed tomorrow night.

Use a tapered punch and work your way up in size until a 1/2" or 3/8" npt hose fitting will fit just inside the tapered hole you made from the punch. Next use a air ratchet or rattle gun to screw the fitting in.

No sparks, no heat or swarf using my method. Done that on several engines that are still in the car all with success.

Do you have much turbo to bonnet clearance?

This will,work better

What do I think?? Crap. You will most likely suffer boost creep with the wastegate mounted there.

super effort Ken.

i also have another page that has been going for a few years now dedicated to the 250 2v engine. Love these engines.
