boost source Size Garrett gt28 gen2

Tried to make 1/8npt threads into compressor house of the turbo for my EBC. Threads got fu#ked and ended up with and elongated hole, so I do have good amount and nice threads 90% of the hole but 10% I only had 1-2threads there and rest of it is flush on that side of the hole..

So my idea is to do M12 x 1.25 to AN4 with braided lines instead of 1/8npt to 4mm vacuum silicone hose. 
and hopefully get a better thread.

M12 is quite big and AN4 is a little bit bigger than 4mm (4.9mm inner diameter braided PTFE hose).

but this should work. Thoughts?

Otherwise I will weld and adapter onto the turbo.

If there's enough meat in the housing where you want to put the M12 adapter, then do it, but be aware that if/when you f**k that up you'll probably be repairing it before doing anything else.

I'd just drill it out and tap ina 1/4" thread. No need for rocket surgery when the next most obvious thing will do. You could throw a 1/4 x 1/8 bush in there and use the same fitting you intended to use.

ok.

Yea, then I would need to remove the turbo and weld an adapter on to it instead, if I fuc* this one up.

You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

Impossible to remove the housing while turbo is installed on the manifold on the engine. So I have to do it anyways. I plugged it so there will not be any debris in there. Will vacuum aswell
