Hi Don;
        Also meant to ask if you have removed and replaced the stock 20B
    exhaust
        sleeve inserts.
        I have heard they are quite restrictive and many people replace
    them
        with 13b turbo inserts.
        Although removing them is a good way to break taps...
        Cheers

    I haven't removed my exhaust inserts yet, but I've been considering it.
    Any tips on how to do this?  Why not just port out the ones that are
    already there?

Hi Don;
I have had limited success...
Some people seem to have it down to an art, there may be an easier way.
I drilled and tapped the roll pins to insert the highest strength bolt I
could find.
I have broken several taps this way.
A small hit with a hammer will help loosen the pins before being tapped.

I have also heard of people drilling them out completely and others
welding something to grip to the pin.

I would practice on a junk housing first.
