Large blocks of time, and the willingness to turn piles of money into
parts.  Don't under estimate the cost of the tools to do the job either,
after doing so many major changes to mine and other peoples cars, I've
probably over a thousand into my tools alone.

>For instance,
>could I use the 2.0 head as well, or do I need the 1.8?

Either head works.  Many people recommend the 1.8 head stock due to
it's slightly better flowing intake ports.

Yes, the castings are almost identical between the 1.8 and 2.0 head.  All
the same bolt holes are on both.

When doing the swap, I would suggest using CIS-E initially as it's much
simpler to get running.  Just removes a major variable from getting it
right.  Speaking as someone that has actually done a Motronic conversion,
it's not difficult but it can get expensive.  There's also more to go
wrong which will affect how well the engine runs if it runs at all.

>Or is it not even much harder to use Motronic?

It's 7 wires between the car harness / relay plate and Motronic harnesses,
you just have to know where they go.  Add a few more sensors, tons of
soldering, rewiring, and harness rerouting.

> What all must be done as far as wiring harnesses
>go if I am to use the motronic or cis-e injection?

Hard to answer this question.  You put it in correctly.  You route the
wires to sensors they go to.  With Motronic, you have to remove quite
a bit of the harness, and greatly shorten some of the portions left.
Mount the box(es) in the rain tray, start car.

>The motormounts should be
>the same, right?

Between 1.8 and 2L?  Yes.

>Can I just use the scirocco 16v manifold and downpipe?

You will have to, the A2 16v units won't work.  They are offset to the
side, while the A1 units go up the middle.

>Will  it bolt right up to my current stock cat?

No, the 16v cars use an integrated downpipe and cat stock.  You can replace
that with a TT style DP that eliminates the cat.

Yes.

Sounds like you just might be dreamin' a little here, eh? :)  In working
on my car, I have found _THE_ absolute most critical component is:
Another Car.  That way, there's no pressure to get your best car on the
road the next day, and you can take your time and do it right.  save up
the money to buy the parts you _really_ want...all that.

Good luck Tim, I hope your car dream comes true.  I've been working on
mine for 9 years and I'm JUST getting to some things now that I envisioned
doing when I bought the car.
