Doing this swap , watched your whole vid!
Awesome video! Great wealth of knowledge! Thanks!
No worries! I hope it helps you out.
Appreciate the videos . I driven vw diesel for a long time . Basics transportation for me . Going from a 1.6 na to tdi was a big deal back then . I owned both TDI vw from car dealers . But managed to get them right and make them last . Thanks for the video . I like to have a Jeep or a Toyota 4x4. TDI . . I not a big hp guy just reliability and good fuel economy. Driven easy what kind of fuel economy can a guy expect from a TDI Jeep . Thanks
That depends on a ton of factors: lift, tire size and weight, rim size and weight, gearing, aerodynamics of vehicle ETC. I know with the CJ I get 30 MPG driving 55 MPH with 33 mud tires, and 4.10 gears. Kyle Meister gets 20 MPG in Wyoming doing 80 MPH in a Dakota on one ton axles, and some decently sized tires with an AW4. If you plan to spend thousands of dollars to get a 4x4 vehicle swapped, it might be better to just get a used, reliable 4x4, and with the money saved from the swap you pay for gas. But there is a uniqueness with these swaps as well. I do it mostly because it's fun.
thanks for this video
You're welcome Jesus!
Jarod March did my injectors for my 11mm ALH swap. They work great. I'm very happy with them
I have two sets of his injectors, and will getting another set for my third engine here at the house. Still unsure on what size I want them.
Good video bro, just a question I have an alh with vnt17 turbo 11mm pump and bigger nozzles Malone tune for the mods it was owned by a friend of mine I bout it from him it’s having an issue with no CEL on but it smokes like it’s on fire on startup for awhile until it’s a little warmer and rough idles it sounds better after it’s up to temp and drives okay in higher rpm’s and suggestions what might be the issue I was thinking leaking injectors or maybe a pump issue? Any advice is appreciated
Sorry for the delay.
I could check the codes with VCDS/VAG Com or OBDEleven. Not an OBD scanner, not ScanGauge, one of those two setups and see what it says.
Sorry if i missed but when do you build full boost with the he200 turbo also what size housing is it i heard the 4cm version spools very good down low with the tdi thanks.
I have the 5CM and it spools pretty quickly. In truth I haven't tested to see how fast it would spool (from 1500 RPM at full throttle), but from everything I've been told it spools just as fast as the stock VNT15 that came with my ALH. The GTD1756 that will be going in the XJ spools STUPID fast. Like 30 PSI by 2100 RPMs.
Hey! Did you like the GTD 1756 turbo? Im thinking a gtd1752vrk for my toyota BEW swap. Going for high MPG and low EGT's. I like the kp39 a lot, as it is very responsive and im fairly happy with the torque. But my tune gets pretty hot between 2400 and 3000 rpm. I think the turbo is running at its maximum, and wondered if the 1752vrk would help. Why did you switch to the holset?
You can't beat a GTD turbo in comparison to anything. The Holset is a great turbo, don't get me wrong, but a GTD spools instantly and the EGTs are good as well.
Your tune might also be the source of EGTs. I ran a Stevenson tune, YEARS ago, and it was absolute shit when it came to power and EGTs. Tekmektronics is the way.
I am installing an 11mm pump in my alha but i was wondering what IQ to set my pumt to and what timing to set it. The car is running 0.216 nozzels tune and vnt 17 making 170 hps. I was thinking most advanced close to green line and around 4mg IQ
Everything I've read and been told is 3.4-3.6 for IQ. That's what I run.
Is it typical to have air in the return lines between injector bodies? If not, how do you purge it?
You sometimes can have air bubbles. It shouldn't be an issue.
I have a AAZ 1.9 TD in my samurai. Recommend anywhere to purchase bigger injectors?
In truth I'm not sure. Not overly familiar with the AAZ. Jarod March is my injector guy. He can be found on FB. He's a guru on the VE injectors.
Kerma tdi
Going to do a tdi swap in a 86 toyota 4x4... have the gut at tdiswaps on youtube do the tune...I want reliability and lil more power and fuel milage than my 22r...( tired of messing with ethanol gas ruining webber carbs) ..is it worth it? Just stock nothen fancy no fancy tunes?
That's Kyle. He's a member of the group and a friend. Is it worth it? That's totally an opinion. To me it's worth it, so much so that I did two of them. Will I ever recoup the costs? Probably not. Is it fun to drive? Every single time I hop into one I fall in love all over again. Your MPG should improve, drastically .
@TDISwap good to kno he is a trustworthy person!.. I just Wana get ecu fixed so don't throw codes and stand alone wiring so I can start the engine up ! Got a jetta tdi on trade but key missing and steering column destroyed.....just trying to learn as much about um as I can !
Im building a 2002 vw jetta 1.9 tdi Im building it for max fuel economy and reliability should I stick with the 10mm pump or go to the 11mm pump?
So, there is a bunch of information that the 10MM should immediately be upgraded to the 11MM. From testing, it's been found that the limits of the 10MM pump, in good working order, is about 280HP. That's more than enough for most of us. Unless you're going for more than that, I'd stick with it.
@@TDISwapInfo im going for 100hp thats it
@@infernoking7504 Then stick with your 10MM if it's healthy.
Do you hook the vacuum pump straight too the break booster
I hook it up the same way it's found in the car. There is a TEE fitting that feeds the N75 side, but it basically goes pump-line-t-line to booster.
I've got a 1z 1.9tdi conversion in my t4 which is underpowered and won't boost. I've changed the n75 valve. Turbo actuator. Got a new turbo cartridge but still no no joy. Any ideas what to check?
Turbo vanes sticking? Stop parts cannon-ing it! lol
@@TDISwapInfo no vains in the turbo. It's the old style turbo 🙃
@@davidhenderson7722 if you have no vanes in the exhaust housing then what is the actuator and N75 for? Lol
Those both control the VNT/VGT mechanism in the turbos.
@@TDISwapInfo never heard of vanes in the exhaust housing before 🧐
@@davidhenderson7722 Yup. They're called vanes. They direct the flow of the exhaust to either allow more to flow out, or stay in the help build boost. If the tune is bad, it leads to sticky vanes which can cause an over-boost or under-boost condition in the ECU and lead to limp mode.
Here is Garrett describing how the double axle vaned ones work, but it's the same shit.

Toyota land cruiser 200_300 tdi pump works
Does it? Yes, but there are plenty of mods that need to be done to get them to work "correctly." My 300TDI pump that came from a "running" engine from across the pond was filled with water. That's from a reputable vendor as well.
Will they work? Yes. Are they getting harder to find? Yes. Are they worth it when Brazilian pumps that make 250 BHP are readily available and accessible? I dunno.
u mentioned techmetronixs for tuning i cant find anything about it where would i look
On Facebook. And it's TekMekTronics
Does anyone have any leads on where to get a mechanical pump for an ALH?
Surely someone other than hahns sells these?
I asked in the Facebook group and nobody seems to have any sources
They are becoming VERY hard to find. There is a group out of Maldova called Blue-Machine Motorsports, although I have no personal experience. Giles Galle in Canada makes good ones, but they are EXPENSIVE! Finally Dieselmeiken makes great pumps and injectors. All are sources.
@David Shoemaker I already bought an engine for the swap on my xj but if I can't find a mechanical pump I may just give up on the whole thing before I even start, really wanted it to be mechanical but it's just hard to even find a pump
@@renosgarage7451 there’s nothing wrong with either. I went with the mechanical pump just to try it out on the CJ. Many folks tend to lean to the mechanical pump because their not comfortable with wiring or they’re concerned with sensor failure. Both of those are easy to deal with. Not saying that’s you, but for some that’s the case.
@@TDISwapInfo I found a rover pump and went with a HE200wg as well, it's almost done
@@JohnSmith-tj5se I bought a known "good" one from one of the reputable vendors from across the pond. It came off a running engine but was filled with water. Ran like absolute garbage, and that's how I found out why.
But if you have a good running pump, make sure you do the governor mod so you don't start defueling early.
Hello! I have a vw Caddy 2002, Ahl 1.9Tdi. My throttle pedal does nothing when pressed, not even an 1rpm increase and i cant find the issue... Any ideas?
Check your codes with VCDS. Either your pedal is bad or wiring is bad. Or you're using the wrong pedal.
@@TDISwapInfo I found the issue, i even took the pump apart the fuel thing inside wasten moving when ignition on, I found a broken cable that fixed it. But I am still not able to throttle the engine rpm.... the car idles on like 500.-600 rmp
@@B3nnyzsif you found something that was wrong, and fixed it, and it still doesn't do it, then the issue isn't fixed. If it's an AHL, then it's basically our AHU here in the states.
Check for codes and go from there.
@@B3nnyzsthe 109 relay is earthed through the ecu I had the same issue car wouldn’t rev up
Who was the tuner you were refering too.
I use Tekmektronics
Я не понял за чем вы убрали электронное управление впрыском , не чего не мешало поставить плунжер 11 мм в родной насос .
При использовании ECU у вас будет большой диапазон регулирования угла впрыска и сохраниться возможность использования турбины с изменяемой геометрией что дас мощность на низких оборотах двигателя.
I like trying things out. There are benefits to both, but not many people have been able to try them both in swap setups and report back their findings. In my CJ7 I did run the fully mechanical 12MM pump with WG turbo, and while it was fine, I did go back to the electronic setup. I more than likely plan to go back to a VNT turbo as well. It is nice to be able to try things on occasion.
I hope this makes sense as I used Google Translate.
Мне нравится пробовать что-то. У обоих есть свои преимущества, но не многие люди смогли опробовать их оба в настройках обмена и сообщить о своих выводах. В моем CJ7 я использовал полностью механический насос диаметром 12 мм с турбонаддувом WG, и, хотя все было в порядке, я вернулся к электронной настройке. Я, скорее всего, тоже планирую вернуться к турбонаддуву VNT. Приятно иметь возможность время от времени что-то пробовать.
Надеюсь, это имеет смысл, поскольку я использовал Google Translate.
Thanks for such an informative video. I've got an 03 MK4 Jetta tdi alh. I'm running the stock 10mm injection pump but have an 11mm I took off a PD. I'm wanting to have it rebuilt with new seals etc and although I'm sure I can get it done, I'll definitely have a qualified person do the work.
I think you mean that you have the 11mm pump off of the Automatic, not the PD. The PDs didn't have VE Pumps.
In truth, the 10MM eTDI injection pump is capable of 300HP. I'm not bs'ing you there. Tekmektronics tested it's capability with the John Deere SV356 turbo. There is no need to swap it out, unless you plan to make much more than that.
If you do plan to get the pump rebuild, look up Verlin Martin. He can make pumps that flow @ 50% higher than the rated capacity. The current record is 43X HP I believe, and that's with a custom 12MM eTDI pump.
Best of luck!
@@TDISwapInfo Aaaaahhhh yes, you're correct. I misspoke on that. I appreciate the constructive criticism and the information on who to go to for reworking the 11mm pump.
Have a blessed day and look forward to more of your content on your tdi builds.
P.S. Do you have contact info for Mr. Martin?
@@FiglioBastardo Honestly, only on Facebook. That's how we communicate.
Here is his shop information on MapQuest though:

@@TDISwapInfo Damn. I'll try to get a hold of the shop directly I guess. I don't use facesucker. At any rate thank you very much!
@@FiglioBastardo Just so you're aware that number is no longer good. I don't have Instagram, but he said he can be found there as well.
