ALH - 11mm pump and 1019 nozzles summary

MK IV - 2000 VW ALH Jetta 5spd manual 312,000 miles

Good afternoon everyone! Just wanted to post a review of what adding an 11mm IP and 1019 nozzles would do to an otherwise stock Jetta ALH.
I had replaced the stock nozzles with 1019's 2000 miles ago.
The Stock 10mm Injection pump replaced with an 11mm auto pump 500 miles ago.
I enjoy reading multiple posts on upgrades before i dive in, and i know there are already other reviews, but here's another to add to the pile. Hopefully it'll help someone make an informed choice.

Performance review:
- After completing the install fully, I was very happy with the result. No loss of mpg after 500 miles of driving. No smoke on start up, idle or under load. No check engine lights.
- Power is substantially better across the whole range of rpm. I have no dyno to measure it on, but the car went from being a slow commuter to a punchy little sedan. Acceleration has certainly gone up, and the extra torque feels great. Can't wait to add more power now in the future.
- All in all, definitely worth the install time and worth the money if the pump can be come by affordably.

Cost review:
- Injector nozzles --- Worth full price brand new
- Injection pump --- Buy used from a junkyard with a warranty or from a trusted member on the forum. For a mostly stock ALH it is NOT WORTH BUYING new or reman.


Nozzle Install:
- Difficulty --- 4/10 --- (doable by a patient and attentive newbie)

Recommendations:
- get new brass washers for reinstalling injectors
- get new glow plugs while your already working in that area
- familiarize yourself with the process of replacing nozzles and bleeding fuel lines on YouTube and the forum prior to beginning


11mm Pump Install:
- Difficulty --- 7/10 --- (overall easy, but requires some time, specialty tools, ross-tech and confidence with engine timing)

Recommendations:
- replace timing belt, tensioner, pulleys, and water pump and fuel filter while your in there
- replace the thermostat which is located under the fuel pump as well
- get new mounting hardware for the install, especially new stretch bolts for the fuel pump pulley
- familiarize yourself with the installation process and timing belt replacement process ahead of time. there are endless posts on these jobs on this forum.

Speed safe!

good stuff, thanks.
I have '02 wagon with 390k on it and it lets out a nice cloud at startup. Still getting 46 ave though.
I am thinking 1019s with stage 1 tune; just resealed the injection pump myself.

I am hoping the clutch holds.

You didn't mention it - was a remap ever done?

 

[Nero Morg]

I have the same pump/nozzles, but with a vnt17 and a remap. Love the tune, but my nozzles came from a poor vendor and causes smoke at startup. Past that runs great. Glad you're liking it.

Whose 1019 nozzles did you buy? And who mounted them?

Same question for me - did you get a remap or running the stock 10mm pump original maps?

Hey sorry for the late reply. Crazy work week.

No remap was done. I’d like to do one soon, but there was no tune on the car at the time of the injector and pump upgrade. Stock turbo as well.

I did reset the pump timing and IQ with vcds after completing the pump replacement.

I bought my nozzles from Kerma, with the copper seal washers and installed them myself. The nozzle replacement was easy! Bleeding the lines was the messy part

Hello. Did kerma advice on those nozzles? Why not the dlc520 instead of the 1019's?

 

[ssaric1.9TDI]

One of my previous Jetta had a set up of 1019's nozzles, 11mm pump with stock VNT15 turbo and RocketChip STG3 tune. Also clutch was upgraded to SMF VR6 one from IDparts. All I can tell you is that the car was fantastic, I loved it in every possible way. It was good on economy and also if I wanted some power it was there. It smoked a bit at WOT but not as much as my current wagon. As far as I know the car is still being driven by a fellow in North Carolina, he occasionally sends me updates. Overal I loved the setup, I think the tune is what really opened the car up. 1019's are good for 150-160hp set up of course with upgraded turbo.

 

[Nickmk7]

My 1019’s with stage 3 Malone and 10mm pump smoke like a chimney and nothing seems to help..(IQ, timing). Is it normal?

No professional advice on these. I was satisfied with the maximum advertised and user - certified max horsepower these could provide. Price point was good for me too.

1019's flow a bit more fuel than dlc 520's, not to be confused with race 520's. I had a set in my first Alh and they're fun. Good mileage and good power. Could chirp the tires into 3rd with no tune.

 

[Dubious]

This thread helped a bunch. Really leaning towards 1019's now. Thanks.

Great info

 

[Dubious]

Much as chirping third excites me, makes me think an lsd would help put the power down instead of spending on a tune.

 

[ghohouston]

I'd agree with that. I've not experienced one in a fwd car, but everyone says great things about them.

 

[03TDICommuter]

For several years I owned a 1991 Sentra SE-R that came stock with LSD. Worked wonderfully. Fun little car.

 

[Rrusse11]

An LSD is pricey, but once you've got one, you'll never look back. Transforms the car IMO.

 

[pkhoury]

LSDs are fun. And I'm all for junkyard injection pumps. In fact, all of my ALHs have junkyard injection pumps, and if anything, they get resealed.

Kinda, but it's not that bad once you get the hang of it. I like to pull a vacuum on the return line of the IP, and if I can get the hose off okay, on the return line of the fuel filter. So once that's done, then I'll crack the injector flare nuts open a little, crank like 3 or 4 revolutions, make sure all four injectors have some fuel seeping out the top, cinch them back down, and fire 'er up! IMHO, I don't think that leaves that much mess around.

No smoke on start up, idle or under load. No check engine lights.

You have a unicorn then if you have all that extra fuel and stock mapping and turbo to boot with no extra air via boost. I was going to suggest simply swapping a 3 bar MAP sensor and doing nothing else, but if there's no smoke then leave it alone!!

 

[Nero Morg]

3bar map and a tune for it.

Have been considering this for the additional 20% boost. What and how big are the downsides to not tuning such a rig? Am contemplating either 520's or 1019's to go with it at some point. Sort of unfortunately, the current VNT15 is in fine condition... LOL

[tripLr]

stock maps are 3 bar. you need a 4 bar

 

[Rrusse11]

2.5 Bar MAP Sensor G31 [Facet] (ALH)

This is a stock specification MAP sensor for ALH engined TDIs. Does not fit the BEW. Made by Facet, fits with no modifications....

www.idparts.com

No, stock is 2.5 bar. 3 bar is an ez eupgrade, be aware that it'll lift the boost about 20%. Not a bad option with a good turbo.

 

[PakProtector]

Zackly Rich...for what ever voltage spread the sensor works across, say .5 to 4.5V of a 5V B+. They all get the same B+, and spread the pressure readings across the output...all one needs to do is tell the brains how to interpret that signal. IFF you just swap in the 3Bar with 2.5Bar decoder ring, actual boost will be higher by 20%.

What I don't want to do is turn up the low power boost much; that just wastes power as 15-25 kW of output does not deliver much fuel...but making boost then will take some.
cheers,
Douglas

Changing the MAP sensor may, or may not, throw a CEL.
