VW ALH 1.9L TDI engine with a later LandRover 300TDI injection pump. This is also using a GT15 internal wastegate turbocharger from an AHU engine. Pump is timed at 1.54mm.
This one is a suzuki sidekick transmission with an adapter plate from Acme adapters. its a little weak, but I went with this one to be able to build an underdrive unit from the sidekick transfer case, then mated a stock samurai case to the underdrive. Truthfully I'm planning on either using a toyota w56 or r151 transmission with a toyota landcruiser transfer case when this one gives up the ghost. A jeep ax15 transmission is also a good choice, as is the transmission from i believe a 2005ish chevy colorado as its also a variant of the ax15 but can be found in a 2wd configuration if needed.
Its the stock manifold from the car, but like you said I cut off the top of the intake and welded a plug over the hole. I then added a new port that allowed the turbo to be plumbed in to the side of the intake rather than the top for hood clearance. the factory TDI intake sat too high for the hood to close and dropping the engine down was not an option.
so can I run my AHU with a 300tdi pump and the delivery valves off of my old electronic pump? And time it at 1.54mm and it should go ok? Also did you use the original Vw pump pulley? Or do I need to source a different one? Would the AHH pulley be ok?
Yep, the AHU should run just the same as the ALH. The one thing to note is the hole for the pump snout on the AHU mounting bracket will need to be machined out as its smaller than the ALH. Use the delivery valves off of the electric pump, and you will need to track down a pulley from an ALH. the AHU pulley won't work if I remember correctly. The 1.54mm timing might be a bit aggressive, start lower, like 1.20 and bump it up in small increments until there is no gain in performance and mileage.
@@BTB31 You need a dial gauge, special adapter and extension for the gauge. Screw it in the back of the pump. Then you have to adjust it to a bit of preload (cylinder one at top dead center), turn the engine in opposite running direction , set the dial to 0 when it stopped moving. Then turn the engine in the other direction to until the dial shows the desired value between 1.20 and 1.54. . Then fix the pump shaft and adjust the timing belt sprocket (screws loosened) by turning the engine until flywheel reading shows top dead center. Tighten screws. Finished.
internally no, but i did swap the stock vw delivery valves onto the landrover pump. they are a different length and break pressure. the AHU pump bracket will need to be opened up for the landrover pump to fit. you'll also need to source a pulley and hub for the injection pump off of an ALH engine. also the support bracket on the rear of the pump will need to be modified. I had to cut two in half and weld them together.
@@san25301 the break pressure of the delivery valves is correct for the vw injectors, but most importantly the length is correct. the landrover valves break at a lower pressure, and are shorter. that makes it so the VW injector lines fit.
@@ktmfour1007 this pump is 0460 414 099, not sure exactly what year it is. the earlier ones don't have the TPS and are a bit different but should also work. Rumor has it that the 200TDI pumps have a higher fuel cut RPM and work better for the VW engine, but the 300TDI ones can be modified.
the stock VW AAZ pump. The point of swapping the pump on the ALH and AHU engines is to eliminate the need for a computer and wiring. The AAZ never had a computer.
Funcionará con los inyectores instalados de fábrica. Deberá reemplazar las válvulas en la parte posterior de la bomba del inyector porque las de Land Rover son demasiado largas. Esas válvulas establecerán la presión de la bomba. Estoy usando el traductor de Google, mi español es terrible

Hay 4 de ellos en la parte posterior de la bomba del inyector. No estoy seguro de cómo se llaman en español, pero en inglés son "delivery valves". Las válvulas en la parte posterior de la bomba de inyección de Land Rover son más largas que las piezas de Volkswagen. Los tubos del inyector no encajarán con las partes más largas.
Hii .. I having similar setup with AHU engine with Isuzu Trooper pump.. recently got misfire in one cylinder.. :( is it possible something wrong with timing ?
Bad timing could cause damage that could cause a misfire on a single cylinder, but its not likely that correcting the timing would fix it if that occurred. Try bleeding the injector lines, air in the line can cause a misfire. If that does not correct it, a compression test would be required then further diagnostics based on those findings.
Not really. The cam plate inside the pump is different. The IDI engines have a much lower injection pressure and a longer injection duration. You can make a TDI run with one of those pumps but it will be slow and smokey with very high EGT temps. Swapping the plate is doable if you have the larger 20mm shaft rather than the 17mm. the 17mm will also work, but have been known to fail. That is why the Landrover pump is so desirable for the swap, it has a more correct cam plate but is also not ideal, hence the rather advanced timing.
No it is an ALH. Both the ALH and the AHU are electronically controlled. This ALH has a LandRover 300 TDI injection pump to allow it to be fully mechanical. No electronics required.
@@MonkeyWithAWrench so can I run my AHU with a 300tdi pump and the delivery valves off of my old electronic pump? And time it at 1.54mm and it should go ok? Also did you use the original Vw pump pulley? Or do I need to source a different one? Would the AHH pulley be ok?
