Garrett GT20 Project

Right, things are moving quickly now. When I was in Aldi, conveniently I saw that they were selling some clamps. They had F shaped ones and G shaped ones which only have one movable part so I thought they would be the strongest which is what I bought:





They are really nice quality as well.

The 8.5mm drill bit that I ordered turned up as well, looks like it is exactly the right size! (for the turbocharger exhaust to manifold holes)

Looking good mate. 10mm is as big as you'll need to go but personally id be going 8.5mm.

How thick is your adaptor plate cos it your gonna tap it then you only need about 7mm for an m8 tap.

As above make sure you clamp it to drill it or do it with q bit of wood on the floor while standing on the plate to stop it spinning. Consider starting with a 5mm bit and working up.

PS I will clean this thread when I get back to civilisation.

My adapter plate is 6mm, the same as what cwspellowe used for his. I was planning to just stand on the plate to drill it but now with my new clamps I can do it comfortably! That reminds me, do you reckon that this template is accurate enough to mark holes for the exhaust flange bolt holes?



Oh yeah and what are you referring to about going for 8.5mm? Do you mean the drill bit or are you talking about the adapter plate? Thanks.
