Keven,
I sell inline four engine coversions at Fast Forward -
http://www.fastforward/ca so I have lots of experience with non-Eurospec
conversions.  First the quick answers (1) No (2) Sometimes (3) See #1

Now for the drawn out answers!

(1)  The kits that I sell do not include any electrical items.  The kit is
designed for the customer who wants to save a few dollars and get some used
componts.  I do provide the service of converting a customer supplied
wiring harness to work in their Vanagon.  I do everything from CIS to
Digifant II to Motronic.  All of the wiring harness that I have converted
for customers do not suffer from "incurable" electrical problems.  There is
the problem that some of the used items attached to the electrical system
doesn't work correctly, but it is not due to the wiring harness or the
wiring harness interface.  The Digifant II system, which is the same system
that Eurospec uses, is a very simple system to convert for use in a Vanagon
requiring me about 2 to 3 hours to do a complete system.

(2)  The majority of our customers do not experience exhaust system
problems.  We do not supply an exhaust system with our conversion kit as
there is just too many different types of exhaust manifold designs out
there and any decent exhaust shop can bend a system for $200 to $300
dollars.  I think all exhaust systems will experience resonance to a
certain degree - the two systems that we are demoing here do not loudly
buzz at any RPM and are quite tame at all RPMs, there is a hint of
vibration around the 3500 RPM range.  The solution is to have the shortest
pipes possible and to have very good bracket / brace that attaches to the
engine with will not allow the muffler to vibrate at all (very important).
Do not use rubber hangers anything else that will allow the exhaust system
to move.

(3)  Hesitations and rough idle mean that something isn't working correctly
with your FI system.  Without being there it is hard to tell what it might
be.  I would link it to your electrical problems.

If you have any questions please give me an email, I would be more than
happy to give you or others assisntance.
