Thanks for all of the answers so far.
1. I am planning on increasing fuel flow so do I just buy injectors with the correct nozzle or can I buy nozzles and install them my self?
2. Is a fuel/lift pump to move the fuel from the tank to the injection pump necessary? Or is it another way to get more fuel into the engine faster?
Also, as an update I found an ALH that I am going to pick up this weekend and have a LR 300 pump on the way. I have a large water to air intercooler that I am going to try to incorporate and hopefully will be doing some assembly in the next week or two.

You can buy the nozzles and have them installed in your current injectors, but for the TDI injectors, that is best done by a shop that has the proper equipment to test them.
Lift pump is not necessary. It can provide extra fuel under some conditions.

Lift pump is super helpful for filter changes, but as Libby mentioned unnecessary unless your fuel tank is going to be very far and substantially lower than your injection pump. If you do install one make sure you can draw fuel through it when it is not operating - there's some Facet Posi-Flow pumps available that fit the bill.

Hi, if you want I found some infos when I was searching for, trying to find the best way to handle torque with an old ahu block.
http://forums.tdiclub.com/showthread.php?t=297234So can you link where you find that BEW pistons won't fit in earlier TDI?
I thought with this link that all 2.tdi pistons will fit.

i am a little confused about what you are asking. I will look for the threads that I found about which heads will fit on which blocks with or without machining. I wasn't saying anything about pistons just which heads and blocks were compatible.

My bad, didn't understand that way! But for me, all 8v hads fits all 8v block (I talk with 2nd gen head design) so for me an alh head will fit on all 8v block since alh ones.

I found this thread at TDIclub
http://forums.tdiclub.com/showthread.php?t=352388there are a few others that say the same thing. The heads will bolt on but the pistons may need to be swapped or machined for valve clearance. I really know very little about this and haven't seen them with my own eyes yet. I have only read about it.
The other issue seems to be that the idler pulley hole is in a different place and needs to be added.
Does this help?
Matt.

Does anyone know of a link or a "how to" that describes the way to set up and time a mTDI 300LR pump on a 2003 ALH? It needs to be simple enough for a chimpanzee like me to follow. I have been reading a lot and I finally bought an engine. The pump is supposedly in the mail and I will have everything to assemble my motor soon. Removing the engine will take a few weeks (I do have a family and a full time job). The one area where I feel I am lacking is how to set up and time the pump. I have read about what is necessary to physically mount the pump and numbers associated with timing the pump but I haven't found anything listing exactly how to make it run or where to measure the 1.46mm. I assume it is out there but I just haven't found it.
Thanks, Matt.

It's pretty straight forward...
- Use the delivery valves from a VW pump (there's a few small parts that will come out when removing them, just make sure everything goes back in the same order)
- Use the ALH timing sprocket and hub
- Time the Land Rover pump to 1.45mm (same procedure as if you were doing a 1.6 or AAZ, there's plenty of guides on here)
That's it!

Why do you advise using vw delivery valves? The one of Landy don't fit the vw fuel lines or is it other?

Exactly. The VW ones are much shorter. You may be able to bend the fuel lines to fit, I gave it a shot on mine but I didn't feel like it was going to work and used the VW ones in the end.

I bought a totaled 2003 pasat with 195xxx miles for $600 and am in the process of removing the engine. I haven't decided/beentold what to do as far as injectors and turbo go. I am able to fabricate well enough to make a manifold and I have no restrictions regarding space so the options are limitless. I understand the basics of how to choose a turbo but not the specifics of the turbo maps etc... i have emailed/PM'd a couple of people and not received a response. I assume that this is because they receive a lot of emails that end up going nowhere.
From what I understand R520 injectors are quite large and seem to fit the hp range that I am looking for but finding an non variable turbo that will deliver enough air so the egt's do go too high and still spool up by 2000 or so rpm is beyond what I have been able to figure out. Also, cheaper is better. So if anyone has any suggestions for me I would love to hear.
My goals are as much power as possible on a stock block using a LR 300 TDI pump and just changing the injectors and turbo and adding a water to air intercooler. When I say "as much power" I mean sustainable power under load.
My dream would be to make 240hp by 4000rpm and be able to run it using consistently using about 150hp at 3000rpm. I really don't know if this is possible but I believe it should be...
any ideas are welcome.
Thanks, Matt.

Hum, a k24 turbo would do the job, but his safe limit is 190-200hp. It begin to spool at 2500 rpm.
If you want to spool earlier I advise you to go with turbo compound, as you say you are not limited with space. In this case you can search for k14 or k16 for the small turbo and k24 or k26 for the big one.

I'd use a newer turbo personally. The K24 and related are very very old designs. They're not particularly efficient.
If you have fabrication skills I'd be looking towards one of the Holset turbos that Alcaid is selling (search Alcaid Holset on here and you'll find some threads)

Alcaid is one of the people I tried to contact. I will try again.
Thanks, Matt.
