Hi guys, yet again Ive hit another brick wall.
So my t28 turbo just arrived and the manifold studs are too big to fit the ones on the turbo flange.
So of course i just widened the holes so i did and it fit alright.
Then I tried to put on the gasket and ofcourse the holes didnt math either because they were too small and when i tried to widen then the gasket just got fucked.
I am therefore unsure if I can find a gasket with 10mm holes...
Any suggestions on what i should do?
Maybe there's an obvious thing I could do that Im forgetting?

Use stepper bits instead of a drill bit to cut the holes bigger in the gasket:




Using a drill bit will bite in and twist the metal causing it to pull up and "rip" things as it does.

The stepper bit will chip away at the material without causing it to pull up, and will simply widen the holes.

Put the gasket against a block of wood to elevate it and allow the weight of the bit and drill pressing to push the gasket flat against the wood while cutting. Will keep things flat as the bit chips away at the holes.

It would be ideal to use a drill press for this to slowly chip away at the gasket holes, but it can be done with a hand drill using slow pressure.

I always grab a scrap piece of wood and use that as the "deadzone" under the gasket.

Those are some pretty good tips guys Thanks

I used your idea and it worked perfectly dude. It chipped away the metal slowly until it made it all through.
Got the turbo all installed yesterday and didnt see any noticeable leaks. i just hope the gasket wont leak as it was a bit rough
