Title: k14 turbo on a TDI??
Post by: xxkoadyxx on September 21, 2012, 11:13:28 am
Hello! I was wondering if I could put my k14 turbo from my TD onto my tdi? To save time in building a new downpipe, and also the k14 has a larger intake opening. I don't see the problem with it. But what do you guys think? I won't be running EGR, ill be blocking it off.

Is this an electronic TDI still? or mechanical? It will need a tune to notice any difference in power I am thinking.

A k14 was recommended to me for my M-TDI build, so apparently it is a good idea. ;) They guy that told me has used them on a few M-TDI swaps.. loves them.

I would always say to go with something bigger but everyone has their own price and driving preference

Seems like it would be too small to be worthwhile...here is a thread I found about it http://forums.tdiclub.com/showthread.php?t=329905 (http://forums.tdiclub.com/showthread.php?t=329905)

They are a step up from the K03.  There's a little more lag but noticeably more power for similar boost.  The increase in power becomes progressively more noticeable over 10 psi of boost.  The K14 is also a more robust unit with a thicker shaft and better bearing support.  If going with a K14, be sure to get one from the AAZ and not from a 1.6ECO motor as the AAZ version has a larger compressor wheel.  You can tell the difference externally by the fact that the AAZ version has 4 bolts holding the center section to the turbine housing instead of 6 with the 1.6ECO version.

It works very well too. I will post up dyno slips once it is dyno'd, but estimates are around 180 hp/300 ft lbs since my Sachs VR6 clutch doesn't hold well when you get into it on the highway.

I'm not a fan of vnt turbos simply because wg turbos are more simple and still perform very well.  So it's cool to see someone using one

I share the same sentiments. I have never had to free up a waste gate, unlike every mk4 ALH tdi that I have come across...

I've had to free up several wastegates. 

To free stuck vanes on a VNT all you have to do is take it on a cruise on the freeway or up an extended grade.  My mechanical control is smooth as silk after a couple years of use.  I was working on it today and checked the vanes and they have absolutely no resistance to them.

Take it on a cruise. Riiiiiiiiiiight. Actually no sorry the ones I have dealt with were beyond an Italian tune up. Sea foam poured down the egr passage into the hot side works a treat though! Actually I love the GT2052W because of the simplicity of my system. The tune I am running eliminates the N75 and the MAF, I am running a home made MBC.

Maybe I should have qualified that a little.  If you aren't a total moron who's completely out of touch with your vehicle, when you notice that the vanes are starting to stick, all you have to do is take it on a freeway cruise or up an extended grade and they will be completely cleaned.

Well I have only had to fix other's VNT issues, and from what I can tell most people these days are morons, and drive slower than cold sap, in the left lane.... >:(

Ha ain't that true!  I shouldn't be riding people's ass in a 50hp car haha.  If you never freed a stuck wastegate, you never owned a kkk turbo haha.  Sure vnt is not much more maintenance if at all and it wouldn't have become the diesel industry standard if it was, but that being said wg turbos certainly are no handicap and some people are not related to rube goldberg, So simple is beautiful.
