you can make a nice m tdi pump out of a aaz pump , as that is what i have on my car , but if you want a top pump for max power that takes a lot of work + time
i have a ivico 2.8 pump with the 12mm head , and a 2.5 with a 11mm head but need to make up a spacer for the pully to run true ,
i also have a 200 disco pump that i have moded for more power , its not a strate fit on eather (difrant pump braket and pully) for 1Z needed
the pump that i am running on my other mk 2 golf is a pug 306 with the 20mm shaft and some mild mods 11mm head montigo cam plate adv mod gov mod good daly driver
i have built a m TDI pump from a ford 1.6 diesel pump with every mod that i no , 20mm shaft to 11mm head 1z cam plate + more , it also lines up ok on the pullys to :lol: have yet to fit this pump .
but every pump runs a bit difrant due to some difrant bits fitted . ie there is more than one way to skin a cat , it just depends on what you want out of your pump power wise

I cant see to find any topics regarding the discovery pump, i can get hold of most bits for cheap, I'm thinking Iz engine and discovery pump. how hard is it to convert it?
cheers

Ryanp,
i just fitted a 200tdi pump to an ahu engine (almost identical to 1z)
The main changes to convert are:
the pump mount bracket needs the main hole opening up, (obvious when you offer the new pump up to the bracket)
the 200/300tdi pump has 3 holes instead of 3 slots where it bolts to the bracket, so timing cant be adjusted. You need to either slot the holes in the mount bracket, or find an adjustable pulley.
you will need to make a new plate where the rear of the pump bolts to the mount bracket. (i did anyway).

Cheers for that, are there any discovery pumps to avoid or any better ones to hold out for?
What does the car run like when this is fitted?
Finally, What wiring would the car need if i fitted one of these?
Cheers
Ryan

Don't know about better or worse, i just know from reading on here the 200tdi and 300tdi's work.
re how does it run, cant really say, only had mine running 'on a bench', it ticked over happily, picked up quickly and made boost.
Have yet to drive it, but a proper tdi pump such as the landys should make standard power, give or take a little. Really, you should search the forum, lots of info on here about mtdi's, just have a good read.
Oh, and the wiring: 1 wire to the pump to turn the fuel on, like with the idi's. Couldn't be simpler

well if you use a pump bracket off a na engine its fits perfectly, as the hole is bigger, i just made the holes in the pump longer so the pump could be twisted, these have 11mm pump pistons so surly they will produce more power? also very adjustable, so you can squeeze more fuel out of it and adjust the LDA like you would on a an IDI, as most people know just from playing with the settings alot of power can be gained.
this pump should be able to supply enough fuel for the greadyest of turbos
i was under the impression i was the first to do the disco pump on here, now everyone wants one :roll: wen i get time to properly finish mine ill post up sum figures

'scuse my ignorance....
If the 200 and 300 disco pumps are tdi as stated above - how are you getting them to work as mtdi? Surely they need to be hybrids with IDI pump bodys or have the full electrickery attached?

@ regcheeseman
tdi isn't a reference to the electronics on a pump, an 'mtdi' is still a tdi.
200/300 tdi landrovers are mechanical and not electronic. this is why we are using them for mtdi conversions. Thought you'd read up all about this stuff before your thread about mtdi's not working properly?
Peace,
Monkey Phil

they are manualy operated TDI pumps as standard, with a bigger PP and LDA ect..
wen i bort mine it cost £35 on ebay but since everyone buys them now you are lucky to get one under a £100, though looking at the exchange rate soon that will be $100, i can buy one and send it over if you want?
im suprised no one has one on the road yet to talk about the performance side of things

Rich,
I paid over £100 from mine from a breakers, most breakers will want between £100 and £150 for a pump, they know the value of a new replacement Your 35 quid job is a bargain!! Nice one.
Mine is running but not roadgoing yet, I'll be posting info once it's had some miles on it.
Looking forward to sending one over to giles in summer to see what he can squeeze out of one.

I'd be very interested in one. What are the specs? 10mm, 11mm? It seems they just bolt up?

Mine is running but not roadgoing yet,
Let me know, just as soon as you get it working properly! :wink:
Anyway, like I said, 'scuse my ignorance.....I never realised there were factory mTDIs.
Am I correct that the LT is a mTDI too?

the disco 200 300 pump is loaded with good parts to make a 1.9 vw tdi work very well, got my pump for £5 but it needed a nother camplate and rolers which i had , then with a wee tweek hear and there , a pump good for over 200hp :lol: wish thay were all this easy , and as far as i no all 200 300 disco have the bosch pump . and thay are all 11mm , and you need the 1.6d pump bracket to ,bigger hole for the pump to fit in .

just to add to this thread, does anyone have access to the proper TDI timing advance curve? timing @ 1k rpm & 2k rpm? i recall seeing this on the forum a while back, but forgot which thread had it. this would be good info for calibrating the pumps advance. or even finding out what a 'performance chip' would do to the advance, and then implement that to the mechanical pump.
