Would a Landrover Discovery Pump Work on my 1.9 idi?

[snedboy]

Hi guys I'm looking to fit a pump with on boost enrichment to my ABL motor and VW pumps are a bit thin on the ground around here. Would a Disco 300 tdi pump work or is it controlled by an ecu? Also does anyone know what kind of turbo they run? From the pics I've seen on the net the three bolt flange looks similar to the one on my K14. Sorry if this is common knowledge but a search doesn't bring much up.

There were both mechanically-controlled and electronic LR300 pumps; the mechanicals have the big LDA module on the top, and are almost a perfect drop-in fit for an mTDI, which I assume is what you're looking at, so I imagine they'd work just fine for an IDI, (as an upgrade    pump--the roller camplate and head / plunger are going to be more aggressive and larger, respectively, than the 1.9 IDI ever saw as a stock pump) I think the LR pumps have 11mm plungers, and stock VW IDIs only got 9mm, afaik. The dynamic advance might be different for the LR pump, though. Not sure.

Myself, what I'd do is put an IDI camplate in the LR pump, and call it square.
Do you have any IDI pumps to scavenge parts from?

no idea if a tdi pump will work on a idi... works great for tdi-m though.. what i have on mine...

you wanna talk to 8v of fury... he made his own tdi-m pump from a idi and tdi-e pump...

Thanks for the replies guys. I think I realised after posting that the Disco pump was probably more suited to the M-tdi motor what with it needing higher pressure to run the tdi injectors.

I don't have any spare tdi pumps available so I would be looking at buying two pumps to make one good one

Ultimately I was hoping that I could just pull the pump, turbo and intercooler from a Disco, sorta like a 1.9td tuning kit in a (big metal landrover discovery) box. This may still be do-able but I will need to research it a bit more

Another pump I have heard of being used was from the pre 1995 Renault Espace. I realise this is a euro motor so may not be familiar to you guys, any thoughts on this one?

the pump would be the only part of the land rover that would fit the VW.. i doubt the turbos or manifolds are even close!

also check the rotation,i bought 2 and one of them was not the same side rotation as vw.
didnt know it at the time...

I'm not so sure. The turbo looks like it has a three bolt flange though I haven't figured out what kind of turbo it is yet. k24?

there are about 200 different triangluar 3 bolt flanges out there.. all of them slightly different..

its different, trust me.

Tdi pump on an idi, I wonder if Giles would chime in on the compatibility or the general differences between them

[8v-of-fury]

I have had both apart, I don't really see what it could be. Other than the fact that maybe the 11mm and 12mm heads just are able to produce that much more pressure through the lines to injectors. Being that I am sure DI injectors open at a much higher pressure, they can handle the extra oomph from the pump. The IDI injectors open between what 135-155-?? bar for the 1.6 na, 1.6 td and a.19 aaz respectively.

I and other have made the M-TDI work using only the DI cam plate, springs, rotor and distributor head within a IDI body and lid. I have also heard of people just bolting 1.6 TD pumps and 1.9 AAZ pumps in stock form on to their TDI engine and they will run. Not well, because the throttle lever needs modifying to supply enough fuel for the steeper cam plate.

Giles also told me that the "dwell" of the higher camplates are less and you are injecting that fuel in a shorter time span. In my new pump it took him a bit to get the idle right he said. Something about the bigger head having a different ramp. Lots of variables, I would suspect higher EGT in the idi when using the DI stuff for the bigger head and the ramp differences.

You are right enough. It turns out the three bolt flange I was looking at was for the exhaust downpipe.

Thanks for all the replies. I think I will go for a Renault or Peugeot pump and maybe stick with the stock turbo for the time being

sent you a pm

bought mines on ebay.uk and ebay.de, lots of pumps there...
iveco pumps could also be adapted and have a bigger plunger.

Interesting.  I'm curious if yours runs well, why the Land Rover pump is so desirable?  Especially, if the Land Rover pump needs to be modified, as well.

What's the catch?
