First, starting out, a 25% power upgrade needs 40 HP,
giving a thumb rule of 0.4 bar boost.
Since the unmodified 5kQ gets 1.4 (new, on a good day)
down to 1.3 ( as the car gets old 0, we need to add
boost to get it in the 1.7 to 1.8 bar range.

Since this is over the 1.5 bar fuel cutoff, that needs to
be eliminated or faked out. If best bang for the buck were
considered, and you were willing to stay below 1.5 bar,
two pairs of washers, super-glued together, one pair glued
 to the top of the wastegate chamber, the other below the
spring, would just about be right for adding tension for
adding 20 HP. ( Probably keep the IC and other mileage
weary components intact as well)

I have a few very low current voltage regulators that will
work much better than zeners. I can also supply the resistors
in about the right ratio to get the fuel cutoff moved to 1.8 bar.
I have a few somewhere around, free to good homes...

		OK, Orin, I'll accept that challenge.  Now, does your
e-mail self..
		...Buy several steel washers of the same OD as your
wastegate spring.
		Place one or more, to taste, washer between the
wastegate spring and its upper
		perch. Cost:  depends on the washers but $0.10 each
seems likely.  Perhaps 2 or 3?

		Buy a small soldering iron, a small package of solder, a
zener diode, and a
		resistor, and a long hose clamp.

		Remove the ECU from the car and open it up.  Clip and
remove one lead

		>>>>>>STUFF DELETED..

		Go for a test drive.  YEEEE HAAAW!!!!

		Replace your blown intercooler if you didn't install the
hose clamp.

		Cost:
		$ 0.30  Washers
		$ 4.00  8 mm Wrench to remove nuts holding the wastegate
cap.
		$10.00  soldering iron
		$ 2.00  solder
		$ 3.00  zener
		$ 0.50  resister
		$ 4.00  hose clamps
		_______
		$23.80  total

		Granted, I have not researched the pricing for some of
these items but
		there is still about $75 of your $100 budget to work
with.
