I'm trying to use NA housing on T2 motor na want to swap out exhaust port from t2 to na housing. what is the correct way of doing this? is there a way of removing pins and reusing them? do I have to buy new pins? I just dont feel like spending 1 hour and ruining perfectly good porting bit.

Drill them out with a masonary drillbit.

Or put a screw inthere and pull it out.

get a renesis

Weld a blob of weld on the pin so you can grip it with pliers. Then twist and pull out.



Gring the weld off the pin and re-use

It's just a roll pin, I would get new ones out of a generic kit, unless you couldn't find one small enough.



The idea about tack-welding to it is the weld will stick only to the steel pin and not the aluminum housing.

Colin, you are alive, there is a post in Gen D about your whereabouts.

The welding seems like the easiest way to accomplish removing them in a less time consumming way.

Give this a try.

Thats what I prefer to use. I've seen some people be a little careless and drill the hole out of round or a little bigger than it should be and the exhaust sleeve sits loose in the housing.
