I believe the difference is in the feed pump, cam, head and plunger.
there should be other small differences, but believe me, it WONT pump when wound the other way.
The feed pump is the same, but the case is different. It is machined to send the feed pump pressure to the opposite side of the timing advance piston making the advance go the other way. The plungers are different. Camplates are reversed, but on an IDI that's not all that significant.

So just reverse the camplate and it should work counter-clockwise??

your pump isn't that bad. if you can just adapt the LDA device you should get a decent setup.
what libbypappa meant is that on a IDI the camplate has almost the same profile on both up and down part of the lobes, so it should be the same running normal or backwards, but just that part, everything else doesnt run backwards.

lda is what puts more fuel in according to boost. as the stock pump doesn't have it it will work, but you get smoke off boost, or not enough power on boost, depending on what you do with the max fuel screw.
if I were you, I would put gtd injectors if possible, leave the IP alone and turbo it. (you already mentioned the cooling system mods)
then after its working, tweak if necessary.

no, the other way around, the engine is backwards on the picture, left side: flywheel, IP driven off the end of the camshaft, like the 5cyl engines.
right side= like every other vw engine

cam is driven by the cambelt from the crank, the cam drives the fuel pump and vacuum pump by a double sided belt via a toothed pulley on the pump side
EDIT: thanks gigaz, i must have chopped off the .jpg part of the picture location lol

Why swap the whole pump when the only bit you need is an LDA?
There are plenty of pump tops out there with LDA that have the throttle lever on either side of the centre line.
I'm 99% sure that a pump top from another vehicle will fit your pump.
I have a few bits of pump under my bench at work, I'm back on moday, give us a ring.
01484 519 800, ask for Simon.
Do you know Dan Knight from the Polo forum? DKnight? mate of mine thats all, lives fairly close.
Do you not fancy a G40 on there? theres another thread here about one in Europe, looks 'kin ace to be honest!

http://vwdiesel.net/phpBB/viewtopic.php?t=8398&start=120There is a guy here doing something with this engine...I think. Instead of the LDA and turbo you could go with a super charger of some kind here and it might be spinning the correct way. Just a thought for you to kick around.

I will do simon, i have a gtd pump and injectors and new nozzles on their way to me and i have a spare 1.4 idi pump as well
If the LDA can be fitted then it would save me a lot of hassle.
Yeah, i know of dan, he sells stickers i think??

sjampoo has G40 supercharged this engine already and his work looks top class to me
He is running very lean with no LDA at the moment!!! I can't see how he'll fit on as his metal boost pipe will be in the way??
He has tweaked the injectors to 280bar to run veggie, he has also run heaters etc so he can cold start on veggie too!!

There is no "lean" with a Diesel.
they are throttled by fuel, and only reach stoichometric at full chat.
Basically, the engine is allowed to ingest as much air as it wants, then fuel is added to it to raise engine speed.
With no LDA all thats happening is that the engine isn't getting any extra fuel on boost, above and beyond what is already there, it will work but can be much much better with LDA.
Have a read of some of the other LDA threads, it may make much more sense then.
E-mail me at
[email protected] and I'll send you something to help.
