aaz diesel pump

[foggy]

Hi everyone, I am new to this forum so plz be patient with me.
Iam looking for a Bosch number for a pump of an AAZ engine.I have a
1Z tdi and am looking to convert to a mtdi .Local scrap yard have loads of
bosch pumps but i need number to find correct one Cheers

There is no correct one as a AAZ pump is not right or strong enough for TDI without serious modification.
Bosch didn't fit TDI pumps with 20mm drive shaft (as oposed to 17mm) for a laugh.

I realise that the aaz pump needs mods, and wont perform as good but i have read that people have fitted them with success, and wanted to try
for myself. Are there any 20mm shaft pumps that can be made to fit?
cheers

One thing that people seem to gloss over when installing TDI's is that you end up with crap heaters!

Well thats odd, I cant say I noticed any diffrenece (Both my mates have T25s a 1.9auto and 2.1 auto) never heard em complain when they are in my Mtdi ???

The warm up time may perhaps take an exta mile.........?

Block off the bottom of the rad a bit then (like in the 'old days' )

Does go to show though how much more thermally efficient DI is than IDI, in this modern incarnation

A guy in the states wrekons a vw TDI will run all day at tick over speed (no load) without the water pump belt fitted.
He said providing the block/head has water in it, it will run all day.

They cant be run 'dry' but they can be run without a pump belt with no long term damage.

Spooky !

Of course, long term idling is not good for engines - and especially don't do this if the engine isn't run-in, else it never will

Should you wish to experiment
