I would like to thanks to everyone for all the replies to the initial
posting. There seems to be lots of questions, so I will answer them all in
one email for the benefit of everyone:
Q - Is the injection pump mounted at a different than normal angle? It sure
looks different than my dad's TDI engine in his Passat.
A - The earlier 1Z / AHU TDIs have the injector pump mounted differently.
There is nothing "trick" about the pump installation.
Q - The oil filler hap on the valve cover is missing! How about filling the
oil? Where was that moved to?
A - The original oil filler cap sticks up quite high, so I sealed off that
opening. Oil can be added to the system by removing the back cap on top of
the cartridge style oil filter.
Q - You indicate on www.fastforward.ca that the ALH/BEW/BEV 1.9L TDI motor
can be modified up to 137hp. Could one get 137hp power with the ALH "under
the cover" setup?
A - The ALH can be easily modified to more than 137hp by changing injectors
and increasing the boost to compensate for more fuel. The reference to the
137hp engine is the 2.0L Passat engine. So, yes, one can certainly get
137hp or more with the "under cover" setup - remember it isn't horse power
that you drive with, it's the torque! At 140hp you have almost 350ft.lbs of
torque! :-) Currently I am building an ALH TDI with the larger turbo from
the V6 Audi, some genuine Bosch R-TDI nozzles plus some custom software. My
goal is for a very "relaxed" 150hp and 350ft.lbs of torque - this combo can
be pushed to over 200hp but I don't want to overstress the engine.
Q - 30mph, is that US or Imperial.
A - Good question, and that is why I hate using the "non-Metric" system. My
average for my very heavy Syncro Tristar is 8.5L per 100km. This is about
27 US MPG or about 33 Imperial MPG. I have US customers saying they get
more than 30 US MPG. It all really depends on how fast you drive and what
you drive.
Q - Is there a loss in ground clearance?
A - You are looking at the skid plate on a Syncro being about 1 to 1.5"
lower than stock. Nothing too significant and after polling a lot of
people, much more desirable than modifying the engine cover.
Q - Is the immobilizer system retained with the install?
A - It depends on what ALH motor you use. There are three types of ALH
engines. All pre 2000 model year do not have an IMMO. 2000 and 2001
(IMMO2) can be eliminated via a software upgrade to the ECU (like this
installation). 2002 and 2003 (IMMO3) can not be eliminated.
Q - Does it utilize an OBD port?
A - Most certainly! When I do a conversion, it is done correctly! With out
the OBD port you would have no way of fine tuning the running of the engine
or in the event of a sensor failing, no way of checking fault codes. The
OBD port is under the rear seat next to the ECU that is in the stock
location.
I hope I didn't miss any questions!
