I am curious as to what I can do to improve the boost on my '83 5000 Turbo. It
is a bone stock turbo (I don't know exactly what model KKK), wastegate, and has
no intercooler. Specifically, my questions are:
1.) Can I add an intercooler to this car by finding a used intercooler and
plumbing from a newer turbo? Which model years should I look for if so?
2.) How can I modify the wastegate to change the opening pressure? Is it as
simple (?) as changing the spring inside? I have also read of adjustable ones.
This sounds nice.
3.) What kinds of computer mods can I do?
I have noticed that on extremely cold days here in Iowa (-20 deg F), my
wastegate seems to get stuck, and it doesn't release when it should (boost gauge
shows ~2 bar abs.). This results in extreme fun. The boost gets high enough to
cause the computer to kill the ignition due to overboost when this happens. I
like the feel of the car in these conditions, but wish I didn't have to freeze
my *ss off to do so!
Thanks in Advance!
