Why not keep it simple and control boost mechanically
with a stiffer spring and modifying the WG to make it
adjustable? A WG cap from an older car should be
adjustable. The stock adjuster can be replaced with
a modified bolt that is much longer than the stock
adjuster and will give you higher spring tension Vs
the stock adjuster. You can do a lot with the WG
mechanically for far fewer $$$ Vs some fancy
electronic device or pressure regulator. The Stage II
IA spring and WG bolt setup I run can go as high as
18 PSI and has non of the inconsistent behaviour
of the pressure-regulation setups. This setup has
been totally reliable for years on the ur-Q. You could
also eliminate the CPU control of the WG in the 5KQs
by disconnecting the hoses from the WG and using
the same setup as above.
