so i was bored the other day. and decided to update my previous list a bit. note i have still only actually used kia pumps on the mtdi engines i have made.
Update mostly a bunch of Sofim engine pumps that are new, and some corrections. With the Sofim engines i have just written the engine that they came on and the engine name

Kia Carnival 2.9 d/td/tdi 0 460 414 193, 0 460 414 191, 0 460 414 178, 0 460 414 207, still the one im using and is currently running in a mk2 Golf and 2 T3/T25/Vanagon campers. If i remember right the only mod i had to do was make the mounting hole bigger. and re drill some holes in the rear pump mount i used the tdi one. and i use the tdi pulley because the Kia one sticks out to far. and on two of the pumps there was also what i think is an immobilizer that i had to remove. and i have used 1.6td mounts for the throttle cable i just had to grind a notch off. mostly because i knew that the length of the cable would fit on my Golf

Iveco Fiat Peugeot Citroen Renault 8140.21/8144.21 2.5 TD? 0 460 414 026, 0 460 414 038, 0 460 414 060, 0 460 414 008,

Iveco Fiat Peugeot Citroen Renault 8140.23/43 2,8 TD/TDI 0 460 424 124, 0 460 424 125, 0 460 424 137, 0 460 424 136, 0 460 424 139, 0 460 424 141, 0 460 424 142, 0 460 424 148, 0 460 424 152, 0 460 424 157, 0 460 424 164, 

Iveco Fiat Peugeot Citroen Renault 8140.27 2.5 TD 0 460 414 081, 0 460 414 054, these engines are according to wikipedia also direct injection

Iveco Fiat Peugeot Citroen Renault 8140.47 2.5 TDI 0 460 414 164, 0 460 414 105, 0 460 414 128, 0 460 414 116, 0 460 414 121, 0 460 414 116, 0 460 414 120, 0 460 414 128, 0 460 414 129,

Addition i got my hands on a 0460424177 Iveco Daily 2.8 tdi pump the other day, it has the small neck so it don't need the pump bracket enlarged so that might be the same on all off the sofim pumps. And i am running the kia pumps on AHU/AFN style engines,

Great to hear that confirmation!  Now, did you look at it any further to see how the timing belt alignment would be versus a VW TDI pump?

There are 4 or 5 of these New Old Stock in ebay currently in Japan, Singapore, etc for about $900-/+ shipped.

They were on a 2.8L 4-cyl turbodiesel that made 124 horsepower stock.
They also have a 12mm pump head...
That looks to be the highest output of the Sofim 8140.43 2.8L turbo DI engines until they went to a common rail design immediately following.

These are definitely intriguing!

JFKO, any chance you could do a further comparison of the suitability of these pumps for a VW mechanical pump swap?

Did anyone happen to archive Hey's original posts with the photos he shared?  I've checked the Wayback machine with no success.  Alternatively, does anyone know of another guide for how to build a mTDI pump?  Many say to "read the forms" but I've yet to find another conclusive source for info aside from Hey.

Are you looking for info on how to tune an mTDI pump, on how to rebuild a Bosch VE mechanical pump, or are you trying to find info on how to build a direct injection pump out of an older VW indirect injection pump?  If you were asking for the latter, I highly advise against attempting that if you need a step by step writeup to guide you.  The pump itself needs bored out from 17mm to 20mm to take the stronger main shaft that the direct injection pressures require, as well as needing someone who knows advanced tuning and setup on the dynamic timing and governor areas of the pump. 

I can guide you to a decent rebuild tutorial at least, if that is what you are looking for, but I'd highly suggest getting a Land Rover pump from doing a web search using quotation marks around the pump number to find salvage shops selling them for cheap, and then do a proper rebuild or at least disassembly, cleaning, and resealing of the internals, marking the exact positions and settings of everything as you disassemble them...

This is a really good basic guide, although REALLY doing a proper rebuild means putting it on a Bosch test bench to measure the output of each cylinder's injection quantity as well as other calibrations regarding case pressure etc.    If the internal case pressure is still plenty good, the pump most likely only could really need a good cleaning and resealing.  It's nice to get one that was on a good runner and hasn't been sitting on a shelf for years with the lines not really sealed off.  Or one that'sbeen filled with LiquiMoly Diesel Purge on last run, and properly sealed up for storage after removal.

Sorry, if it was answered here, but I didn't see it.

Has anyone installed a LT 2.8 VE IP (0460424138) on an ALH? I believe I read the snout is smaller on the LT2.8 vs the ALH, so curious how people dealt with this issue?

I know I can use the AHU sprocket on 2.8 LT IP, but the IP mounting portion has me lost.

Thanks!
