Uping the boost in a 5ktq...

[Stephen Ankney]

Listers,
I bought a fairly modified 86 5ktq about 6 months ago. I've been happy with
it's performance until recently when I started to get the "must have more
boost bug":)

What I'm looking for is advice on how to increase the boost a bit. The
cheaper and easier the better!

What I'm looking to do is run 16-17 PSI. Nothing more, nothing less. I'd
also like to get faster spool up.

My current setup is a IA 1.8 bar spring and chip, 2 piece manifold, K26
turbo using the largest cold/hot sides available in the K26 lineup, Schrick
272 cam, etc...

What are peoples opinion's on these following devices and idea's:

Adjustable air pressure regulator: is this as simple as it sounds? Will
plugging one of these into the signal line acheive my boost expectations? I
have purchased the one from Sears that was suggested on Ben Swann's site...

Adjustable Wastegate: I know that this will not give me any more boost. It
will however give me control over quicker spoolup . Should I use the 1.8 bar
spring thats in there or return to the stock 1.4 bar spring when using the
Adj. Wastegate or doesn't it matter?

I assume that I will have to ditch the IA chipped ECU and go to a
zener/resistor modded ECU due to the 1.8 bar fuel cutoff, or is there a way
around this with the IA ECU? I do have an extra ECU so it's not a big deal
if I have to modify one...

Paul Timmermans "schrapnnel knobben" device. I'm a little fuzzy on what this
actually is? Anyone have pics of this setup?

That's it for now. I have so many questions. Hopefully someone can steer me
in the right direction...
