TDI Roc, updated info and more questions

[Cory_Langford at bcit.ca (Cory Langford)]

So from the great responses I have so far here is what I have compiled:

The best engines to source for the swap would be either the AHU or 1Z 
engine from an A3 jetta or B3 passat.

I will need all the engine electronics (obviously) as well as the pedal 
position pot. and the electronics associated with the DBW arrangement.

I will loose all the fuel pumps, etc except for the intake prepump, and 
will need to reroute the fuel lines around the missing equipment.

Stick with a cable shift tranny unless you can build a really strong 020 
:)

The TDI engine may have clearance issues with stress bars/hood like an aba 
swap??



Questions that have popped up:

I noticed a few places mentioning a water separator.  Is this something 
that comes with the fuel system of a TDI that I should grab, or is this an 
extra add-on to source?

What about the Tac?  With out a coil to trigger the tac I doubt it will 
work :)  So What options are there for a tac for a TDI?  I also assume 
being a diesel that the red line is very low.

The DBW pedal position pot.  I noticed pictures on the tdi club of people 
using the entire pedal from a TDI.  The pot looks like it is attached to 
the pedal directly.  On the older cars was it in a separate place? 

because the injection pump is at such high pressure, I am assuming it is 
mounted to the engine (or close to it) and thus we only have to run lines 
to it from the pick up pump?

Most likely I will have to get a VagCom to reprogram the ECU?  I am 
thinking that the ECU may have issues when it notices that the abs, air 
bags, etc, etc are no longer connected.  Or were there old tdi's that had 
none of these things?
