Charlie Spring

[aeciepli@undergrad.math.uwaterloo.ca (Avi Cieplinski)]

        So, where can I pick up one of these charlie springs for the
wastegate. Also, how hard is it to switch the wastegate spring? Also, this
might sound stupid, but where is the wastegate located? (I don't have a
Bentley manual for the car... yet!) Who has the best price on a set of
repair manuals?

Finally, what kind of hp increase can I expect from installing a K&N filter?
I just put in a new 2 1/4 inch cat-back exhaust and I am really happy with
the results, and I have a filter on order.

I have an '85 5kcdt in case it matters.

Thanks.
