Turbo/wastegate questions - K24, WG Spring etc.

["Swann, Benjamin R. (BSWANN)" <BSWANN@arinc.com>]

I just wanted to thank everyone for replying to my questions and then some.
This dissertation I believe is very useful in that the home mechanic can
actually do something about performance at various levels, especially for
normal driving applications in addition to racing.   As I'm still learning,
and there seem to be some differences of opinion, I will hold off making any
mods. for now, still leaning toward shimming the Spring or getting a
different spring.

Since I've never actually cracked the wastegate open, are there any diagrams
of a wastegate blowup.  did not find any in Bently or SJM great site.  How
difficult is it really to replace a spring or install a shim?  I'm willing
to try new things, but not if they are likely to cause irreversable harm.
Javads adjustable cap seems to be a pretty good idea, but I can't even tell
how it would work without seeing a full diagram of a wastgate assembly  Got
pictures in my head from what everyone's saying, but..any diagrams?

Regarding Phils last comments though.  Have I lost some of my low end boost
by Bypassing WGFV with pressure regulator which I understand is a popular
and inexpensive mod.  Would it benefit to tee the original line back in
using a one way valves so you get the vacuem lift on the low end,  and the
needed bypass on the high end(trying to explain what I think againg without
actually knowing what one of these looks like taken apart).

My apologies to those who sell the mod kits by the way, as I'm sure they are
worth it.  Some of us just can't afford or justify expensive chips, new
turbos and the like.  I'm not a racer, don't have the money or time - maybe
some day.  Just want to get the best performance available without spending
more than the car is actually worth.   I learn from the expert advice on
this list and other sources, and then I'll apply what I've learned if
prudent as a home mechanic/hobbyist.

Thanks again for all the replies - keep 'em coming.  Happy Thanksgiving!

Cheers,

Ben Swann
