TDI Swaps: Injection pumps, Injectors, and Turbos. A brief explanation. 

Turbo vanes sticking? Stop parts cannon-ing it! lol

@@TDISwap 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.

@@TDISwap 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. www.garrettmotion.com/news/newsroom/article/what-is-a-double-axle-vnt-turbo/

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.

On Facebook. And it's TekMekTronics

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

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 !

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.

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.

@@TDISwap im going for 100hp thats it

@@infernoking7504 Then stick with your 10MM if it's healthy.

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.

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.

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.

Everything I've read and been told is 3.4-3.6 for IQ. That's what I run.

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.

You sometimes can have air bubbles. It shouldn't be an issue.

Check your codes with VCDS. Either your pedal is bad or wiring is bad. Or you're using the wrong pedal.

@@TDISwap 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

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 use Tekmektronics

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!

@@TDISwap 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: www.mapquest.com/us/pennsylvania/martins-repair-service-2102292

@@TDISwap 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.

No worries! I hope it helps you out.

You're welcome Jesus!

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.
