Vanagon TDI AHU Swap: MTDI Pump

[@billbourg2558]

Very clean installation JT. Nice to meet you and thanks for the tour.

[@jtlachappelle]

Awesome...likewise man!

[@OlisGarage]

Glad you mentioned Giles. He also has a huge reputation in the vw mk1 community.

[@bryandickerson5365]

I'll be more than happy to give Giles my money once I'm confident the MTDI will give me the performance and mileage that I'd like. The AHU converted car I drove awhile back was electronically controlled and awesome, but I just don't want to deal with VW electronics. I want my car to be dead reliable so I can feel confident driving to, let's say, Alaska. Looking forward to having you visit the farm! You might even want to take a look around the "gateway to the Columbia River Gorge" before continuing south.

[@jtlachappelle]

Cool. The performance will satisfy you, definitely. Ill take you for a ride or even let you drive this thing and youll see. For economy, i get 30 to 35 all the time, and i still dont even have an intercooler. I have a feeling once you check mine out youll be ready to get an MTDI. Ill message you at your website when i know for sure when im coming

[@floringhetu4005]

Nice work. What glowplug relay are you using?

[@nickzander11030]

I’m looking to do this swap. I live in Vancouver Washington. If you still have this, I’d love to check it out!

[@pimpmyrustbucket]

van is in Canada...?

[@christophererb4382]

Hey man, this is Chris from the pct, I found your channel.

[@jtlachappelle]

Sweet. Keep killing it out there. Talk mexico later...

[@juanalcantara4945]

Hello I have a 1993 vw Eurovan l swamp a ALH engine l want swamp a 1997 vw Passat cluster do you have idea we’re l can get parts or diagram to installation

[@baldynamnam]

Where are you running the coolant hose that is connected to the transmission side of the head? Spotted at about 2:50. Thanks.

[@jtlachappelle]

Its in the original factory location, factory routing, goes down and to the right, sort of under the fuel filter. The AHU is identical to the original 1.6NA as far as all of that goes, coolant flange locations, mounting brackets, etc. Or, what did you mean?

[@baldynamnam]

Thanks for the reply! That is what I mean't yeah. I'm working on an mTDI conversion and still figuring out some misc items. One of those items is where to run that coolant outlet since the eTDI routes it to the EGR, which has been removed. Thanks.

[@jtlachappelle]

Wait...so i take it the van youre converting isnt a factory diesel, its a gas van? In that case you wont have the original aluminum coolant flange like i have, but im sure you can use the factory TDI plastic flange and route the hose like i did. Thing is i think i remember that flange not having the right sensors, but if youve got the skills to undertake this conversion youre on top of all that anyway.

[@baldynamnam]

Yeah it's a gas van. I have the aluminum flange too. On the gas vans the main inlet and outlet coolant hoses are on the passenger side of the engine compartment and the only other hoses that leave the engine compartment are for the heater circuit, which is why I was curious where your hose from the engine head was going. Thanks!

[@leeburke4041]

Hey great video I was just wondering what turbo are you using i have a ahu engine and I don't want the Hassel of wiring so could you use a diesel pump off the aaz engine the TD engine

[@jtlachappelle]

K03 turbo. Not sure about the pump question, call Giles at Performance Diesel, he knows everything

[@reddundun]

Hi, Nice conversion, whats the comparison of power from the mTdi and older 1.9 td AAZ?? i run the older 1.9 td because like you say the simplicity is what i love about it, I'm also not a big fan of electronics, alot of good info here thanks for your time and info, so another sub here

[@jtlachappelle]

Cool. I understand that the AAZ is not direct injection, so its around 15% less efficient/powerful than the direct injection AHU right off the bat, plus whatever other improvements the next generation AHU presumably has over the AAZ, like higher injection pressure and who knows what else. Generally diesel tech improves over time with each generation, so the rule would be to go with as modern a motor as possible until complexity makes it impractical. As far as i know the AHU is the most modern motor thats still easy to put in a vanagon. But theres a ton of discussion out there on that....lots of reading

[@bahopik]

very clean swap! what runs your waste gate now that you got rid off ECM? thanks

[@jtlachappelle]

Just turbo pressure going into the factory wastegate controller, or whatever its called

[@CoghiF]

HI, very nice project. I am doing a swap on my vanagon. but my engine have a electronic diesel pumps, My donor car was a audi A4 19.TDI, Could you give more informtacion about yout M-TDI pump and the parts o any web site to buy one.

[@jtlachappelle]

You watched the video right? Check out Performance Diesel Injection in canada, as far as i know theyre the only place to buy a trustworthy prebuilt MTDI pump. You can also ask Westyventures but i dont think he has any anymore

[@ctbradey]

@@jtlachappelle have you heard anything about Haans Auto in North Carolina?

[@jtlachappelle]

@@ctbradey Im going say "no comment" and say that the quickest internet search will start you on a trail that will reveal an exceedingly obvious and definitive answer to that question. Ill also say to please, please go search it before you buy from him. You can also ask Karl at Westy Ventures what he thinks.

[@jtlachappelle]

@@ctbradey I thought I replied to this aready....guess not. Are you talking about Hans Auto? Im going to let you do about 30 seconds of searching on the internet for Hans, also known as Prothe, see what sort of results come up. That should be enough.

[@bryandickerson5365]

Hello it,I've been planning an mtdi swap for some time. I'm ready to proceed but would love to see one in the flesh before starting. I live near Portland, Or, would it be possible to meet you and your mtdi Vanagon?

[@jtlachappelle]

Yeah why not. Ill actually be going through there on my way to reno next week, im sure i could stop off down there and grab a bite, let you check it out

[@bryandickerson5365]

Very cool! What's the best way to communicate off-youtube?

[@bryandickerson5365]

Let me know the day and time (roughly) you'll be coming through and I could feed you. We're a small farm so it would probably involve some local meat + our veggies, if you're into that sort of thing. Or I could order out for pizza:^) We're not far from the Portland Metro area so it wouldn't add much to your trip. Thanks for offering and I hope it works out. Not having access to a functioning MTDI has been one of the things holding me back from pulling the trigger on my project. You can contact me through our website - dancingrootsfarm.com

[@jtlachappelle]

Wow, sweet. I was going to say just send me a PM here on youtube if you can, but ill hit you at your website. Itll be next weekend i think, sunday or monday, ill let you know for sure

[@jtlachappelle]

.....and you just have to spend the money on a new pump from Giles, or from Karl if hes got any. Worth every penny. Supposedly theres the option of running the Land Rover pump, but that requires the research and i think a little modification, id just spend the money on the turnkey, known quantity pump from Giles.

[@akdivision47b88]

So the difference from tdi and m-tdi is in the fuel pump??

[@jtlachappelle]

Pretty much. You just delete everything that’s electronically run, go with the original factory diesel vanagon configuration, which is a few sensor wires and a throttle cable, as you saw

[@theshipwright]

What is difference in hp and torque between the mtdi and the etdi?

[@jtlachappelle]

From what I understand theyre pretty close, id imagine the ETDI could be tuned for a bit more

[@BlueMachineOfficielle]

@@jtlachappelle I don't think so, there are the same. You should get the right pump !

[@travisterrell3730]

Do you have the pump model that is required for an AHU M-tdi?

[@jtlachappelle]

Well, apparently Karls pumps were for Cummins 4BT motors, and everyone says the pumps for the Land Rover 300TDI motors can be used too, but the problem is they both require at least some modification to work, beats me exactly what. As far as I know there is no true bolt on production pump you can just go buy...you have to get one thats been modded, preferably by someone reputable like Karl or Giles.

[@jtlachappelle]

So unless you want to find one of those pumps off one of those motors and figure out how to mod it yourself, youre going to have to get one from Karl, if hes still making them, or Giles. Its going to cost you at least $1200, but its totally worth it. Both guys are impeccable.

[@bryandickerson5365]

Hi jt,Have you tried to reach me by email? I haven't seen anything yet. Were you planning to come south tomorrow or Monday or did you mean a week from now?

[@n6y6h6]

I prefer the normal the vanagon. A lot cheaper .better to monitor..and for only 4 euro you have cruise control

[@n6y6h6]

The normal tdi ;)

[@buggs9950]

mtdi is cheaper to install, cheaper to tune and cheaper to fix.

[@BlueMachineOfficielle]

How many HP ?

[@jtlachappelle]

Its not the HP you want, its the torque. HP, probably around 110. Torque, id bet around 175? Thats with no intercooler, at 13lbs max boost. Very mild tuning right now. I could add an IC and up the boost, way more power and economy

[@njnorbert]

Just buy pump from European AAZ 1.9TD 75hp

[@jtlachappelle]

Interesting, but youd have to do some serious research to be 100% sure it would be compatible / adequate for the AHU TDI. The fueling is what I wonder about...you say that 1.9 is 75hp? Well AHUs are like 110 stock, and most guys mod them and push even more fuel. What exact car/motor would that pump come from?

[@njnorbert]

jtlachappelle AAZ 1.9TD

[@jtlachappelle]

Yeah, i don’t believe thats enough pump for the AHU TDI. Pretty sure thats well established, but i will do some research
