Dennis,

I bought the windage tray through Camelback. It retails for $90 and I think I
got it for around $65. However, right now Impex Parts
(http://www.vwparts.com/index.cfm) is selling them new for $29. Stunning
price.

On the Audi 3A, I am going deeper into the engine and am continually
impressed by the quality and the number of refinements compared to the RV
digifant engine. Just finished a valve job (with the turbo, I don't want to
take this apart again). I found that the cam followers/hydraulic lifters are
significantly larger than the VW equivalent, although the same part number is
given as the replacement. Also the injector gasoline spray path is much
smoother than the RV head. Using SAAB xxx yyy 712 injectors with a defining
spray nozzle on the end, the diameter of the gasoline packet is just 1.5 mm
in diameter less than the port diameter at the intake valve opening. Almost
theoretical charge filling!

Anyway, I would use the Audi manifold with the Digifant injectors (I'm making
a modified hold-down for the fuel rail of the Digifant). You could feed the
system with the RV air flow meter and be within its design margin. Wouldn't
use the Vanagon part because the number on the resistor track is different.
But actually, the SAAB normally aspirated 16 V, 2 liter engine uses an
LH-Jetronic engine management system with the far superior hot wire mass flow
meter. You could get all the parts (injectors, sensors, MAF meter, pressure
regulator and ECU) for around $100 at a local yard. Better than the Digifant
and even more superior when compared to the CIS-E.

I'm using the RV engine alternator and compressor mount plate with no
problems.

I always get the exhaust pipes from my local VW racing Muffler shop. Cheap,
bent to fit or cut and splice mandrels. Elsewise JCW has a full set of
conservative mandrels.
