      2002 1.8t GTI - K04-022
      02-06-2008 04:09 PM #1
      Official K04 Upgrade Info

      K04 Variations

      • K04-001
        Direct bolt on to transverse motors using OE exhaust manifold and oil/coolant lines. Might be good for those k03 (not k03s) owners if you just need something easy to bolt up. SO THIS MEANS DIRECT BOLT ON Golf/GTI/Jetta/Beetle Will work for K03 and K03s but will yield little gains on the k03. Would be good for those with a dying k03/k03s and don't want BT.

      • K04-015
        Direct bolt on for longitudinal motors using OE exhaust manifold and oil/coolant lines. Means Direct bolt on to Passats/Audi

      • K04-020,022,023
        This turbo comes off of the 225hp Audi TT (or S3 or Seat Cupra R and some other European cars). Is not a direct bolt-on, needs more than just basic bolts and such. Don't need any engine mods, but would not hurt. See below for details on installing it one on a transverse vehicle (Transverse mean meaning mk4 G/G/J/B).

      • K04-025
        Direct bolt on for the Audi S4. I believe it comes off of the RS4. More boost for the S4.

      • K04-02X Turbo
      • Exhaust manifold, from Audi Mk1 TT 225hp motor
      • Exhaust up-pipe
        • Pro-Imports has an exhaust adapter so you can use your K03 down pipe on this k04 (THAT IS IF YOU CAN FIND ONE. I believe Pro Imports is out of business).
        • 42 Draft Designs has a full down pipe to be used on this turbo. 42DD Link

      • Oil lines, from an Audi Mk1 TT 225hp motor or Aftermarket from PSI Concepts
      • Water/Coolant lines, from an Audi Mk1 TT 225hp motor or custom ones made from Pro-Imports

      • Oil Feed install tip: if you're using the stock oil feed line (or any line that is hard like that), BE SURE TO TIGHTEN THE SIDE ON THE MOTOR FIRST. If you tighten the turbo first, it will be really difficult to get the banjo bolt to go in straight. (reference post)

      • K04-02x Turbo to Manifold Inserts
        o Some people have said that there are small inserts that go into the turbo manifold and sometimes they come out when you try to unscrew the turbo off from the manifold. Well a guy named Trevor from PA decided to get some machined. It's a worth while investment to have if you are planing to drop your turbo.

      • GIAC Software: has issues with cold starts and cold drivability with the Genesis 380cc injectors. The OEM TT225 injectors run correctly. This is coming from 2 people with 2001 AWW engines, so, at this time, we are unsure if the AWP is affected by this as well. The car will run with the Genesis injectors, it just has cold start and cold drivability issues.
      • From Member eurojulien 318is: You can get k04-022 down pipes from this ebay'er http://myworld.ebay.com/ebaymotors/r...s_performance/. Not sure how it fits, but it's worth a shot for anybody looking.


      General links

      FAQ
      1.)Is this a direct bolt on? What software? What MAF? What is required? What kind of hardware?
      No, it is not a direct bolt on. There is a reason why there is a requirements list. Please refer to the list Click Here or Here) it contains just about everything needed and should answer most questions. As for software, b/c people can't read the list above. REVO, GIAC, Unitronics are the most popular software or "tune". APR does not make software for it. Anybody can lemmiwink any tune but it's not specifically made and is all up to the user to decide if they want to do that.

      2.)Is the k04-001 and k04-2x the same?
      Refer to the official k04 web page: http://www31.brinkster.com/bmxp/K04-02x/Index.html . I don't have the technical aspects of the 2 turbos. I do believe the k04-02x has a thicker shaft vs the k04-001 and different hot and cold side impellers (mainly size and design)

      3.) Why can't I use the 225 Audi TT (or simular ECU)?
      It's never been tried but it's a completely different system.
      This post covers most of it: http://forums.vwvortex.com/zer...39551

      4.) What kind of downpipe do I use? or Can I use my stock?
      Yes and no. If you get the k04-20 adapter from Pro Imports (PI) then you can use the PI adapter to your stock k03 DP. 42dd Also makes a DP for this application, probably a better deal b/c it's a full DP. Also, the Pro Imports adapter is expensive and becoming hard to find, not playing favorites towards a company but like stated before, the 42DD would be the best option for most users that don't want to make one themselves.

      5.) What kind of power do you guys make? Is this kit worth it?
      There are dyno's from miscellaneous types of setups Dynos. It is subjective to ask if this kit is worth it. To me it's a nice fun upgrade for those not willing to go all out with BT and new rods. You can have fun with this setup and is fun to drive. Will it make 28rs numbers no. Unless you have a fully built engine. This setup is very reliable (I've had this kit since May-16-2006). It is up to the end user wither or not they want to spend money on this or go all out. This kit has potential. Somebody is yet to find it.

      6.)What type of IC can I use? What IC do k04-02x users use?
      You can use really any kind of IC. Most 02x users use a FMIC. If you are using a SMIC (stock or aftermarket in the stock location) you will have to modify your upper IC pipe (if you are using wanting to use the stock pipe) the charge pipe from PI is recommended and get some kind of heat wrap because it will cross the exhaust manifold and DP. In addition, if you are using the stock upper IC pipe it will have to be extended at the bottom portion to reach the SMIC/IC. A pic is on Page 49.

      As far as a FMIC it would be a better recommendation. If you are using a eurojet or greddy or "greddy style" I would recommend a new silicone for the turbo to upper IC pipe. I used a 45* silicone reducer (I believe 2.25 to 2") to make it sit better or you can reweld the upper pipe. And yes IC are cool especially FMIC's
      But as far as FMIC fitments goes my greddy pushes down on the TIP. Seems to be normal unless you modified yours. More or less you will have to modify your setting to make it work. There is no solid answer. I do hear PI cuts there and makes it fit, no real answer on that. Also, I do believe PI uses the 225 TT combi vlave to make more room for the TIP to fit, I think they rotate it forward. *Also I do believe PI is the only company that makes a upper IC/charge pipe for this turbo.

      7.) What type of Inlet pipe can I (or do I) use? Stock/Aftermarket? Fitment issues? General Inlet Question?
      You can use either stock (Audi TT) or aftermarket (Stock k03/k03s will not work). Samco, Forge, vinair/ebay versions all work fine. Stock works well too but why not get an aftemarket that flows better and won't collapse on you. There have been some speculation on the little nipple near the top of the TIP. I do believe it is for the PCV/ Emissions purposes. As in the AWD (aww too? I believe) Don't have that nipple before the maf, but the AWP does. I have an AWP and I removed that whole line. I goes the to the brake booster. I have an ABD manifold and I had to remove it and have not had any issues.

      8.) What is the difference between k04-020, 022, 023...?
      Nothing really as far as I know and from what I have read. The difference is how the wastgate is placed. 020 and 022 are fairly similar and the 023 is quite different. Look at the different k04-02x pics above. BUT one thing to note is that the k04-023 has a EGT port in the housing. Other than that.... I think that's it.

      9.) Do I need to build up the engine?
      No, not really... but wouldn't hurt the engine to do so. Most people put the K04 in and it runs fine. Just be careful of early torque spikes, as that is the main reason why rods go out on stock cars. There have only been a handful of people who have built up the engine. But at that point they are (or should) just go to a real big turbo.

      If you got some thing to add PLEASE IM me. So I can add it to make it easier for all of us to access.

      The original thread will be dearly missed. Maybe this one will go better . I need to post something so I can start watching it... so I'll say...

      Someone needs to max out their k04-02x and show what this turbo can really do!

      Now accepting donations . If I had all of the money I'd need I'd do it in a second. I do have some plans in regards to pushing it a little harder, but it's going to be rather long term given my fiscal situation.

      When people say the k04 is a waste of money they usually refer to the k04-001 not the k04-20.

      K04-20, 22, 23 are the biggest ones out of the ko4-001, and k04-015. K04-2x series turbos come on the AUDI TT 225, SEAT LEON CUPRA R, AND AUDI S3.

      Correct me if I'm wrong but didn't REVO come in here and state their car was tuned for the VR6 MAF not the 1.8 sensor+vr housing. I'm not debating which one works better just stating I'm pretty sure that is what they said.

      Yes Chris from REVO came into the other thread and said it was tuned for a VR6 maf and sensor.

      Pro Imports themselves came in the thread and said this:

      "When we performed the original development work with the Revo Engineers on the Stage 3 file for the Equalizer Kit, we used the VR6 MAF housing and sensor. This is the sensor & housing we have always used and sold as part of our Equalizer Turbo Kit.
      Our mission is to provide the best customer support for our customers. We are available to all of our customers at 301-881-4905.

      Customers that have purchased our Equalizer Turbo Kit and are having any issues may get additional technical support via the direct Equalizer Technical Support phone # at 240-477-2122 or via e-mail to Pat@Pro-Imports.com."

      My car runs like poop on a VR6 MAF sensor. However, this has been discussed 1000 times. Truth be told, Revo says 1.8T sensor, PI says VR6 MAF sensor and you can even get different answers from both depending on the day. FWIW, my car is correcting fueling by removing it w/a VR6 MAF sensor and adding it w/a 1.8T. The only difference is w/a VR6 MAF sensor the car has no partial and seems heavier. But that's my car.

      and this is what chris from REVo had to say about the VR6 hosuing and sensor.

      "Hey guys, sorry that there has been so much confusion on this. I have spoken with Pro-Imports this morning and they have said their cars were tuned with the VR6 MAF sensor and housing. This is specific to their kit and apparently was done by them and our engineers. We did not have information on this at our support office.

      So PI k04-020 kit VR6 sensor and housing
      Othe REVO stage III files are to use your stock 1.8t sensor and VR6 housing.

      At this time if you are having any problems or issues please report them to Pro-Imports as they have the most experience with the kit. They will in turn come to us with anything that must be changed."

      Oh yeah... to anyone who may be interested, I'm going to be selling TT225 injectors and a VR6 MAF housing pretty soon. Definitely the injectors, most likely the MAF housing. I also may sell a 4bar FPR, but I'm not certain about that yet (I think I'm going to an adjustable FPR).

      Honestly, that's kind of the truth. I don't know that I have much to contribute at this point. I have plenty of plans for my setup... but they're long term and I don't know that I'll do more than explain the changes and maybe post a dyno. There needs to be some new people posting logs and sharing info. I'll happily input my .02, but I think I'm about done actively trying to forward the k04-02x community with my car's logs and setup info. They're all on the official dyno thread now so I don't really need to explain them much more I guess.

      I'll continue to poke my head in and anyone who has any questions please feel free to contact me, but I think almost everything that anyone is thinking of has been discussed by now.

      For anyone trying to put one of these kits together...

      I currently have a 3" MAF housing (shaved down ridge so it'll slide into a CAI as well as stock airbox) for sale (could get a VR MAF sensor for it as well as I have one that I use for logging), 4bar FPR (~12k, I'm switching to adjustable), and 4 x Audi TT225 injectors (extra set w/~7k on them). Hit me up via PM if anyone needs any of the following for their setup.

      i also have a full k0420 kit for sale

      I highly doubt someone will have a k04-20 uppipe laying around. I had one but sold it for 100 bucks. You're going to have to buy one from Pro IMports, 42DD or get one from an audi tt 225 and modify it.

    26. 02-16-2008 02:43 PM #26
      Just like Golf/Jetta inlet pipes, TT225's have 2 different pipes (probably for the same reason, an extra port). If you have a more recent TIP for your G/J (AWP for instance), do you need the newer one from the TT225?

      Nah, you can block off the one port anyhow. I did. No big deal at all.

      Yeah, I have had no luck in finding this part. I tried calling everywhere and cannot find it. All of them come in a kit only, or not at all. If anyone knows for "SURE" where I can get one, PLEASE let me know.

      pi sells just the up-pipe, if you called them and they said no, then it sounds like they wised up

    30. 02-18-2008 09:33 AM #30
      please read

      Please keep this thread to the discussion of this turbo upgrade and not random chit chat. Also as new/more info is avaliable please make sure that it gets added to the first post so that as the number of pages in the thread climbs finding information is not an issue.

      I don't know which of the two pics below is the more accurate information regarding the dimensions of the k04-2x series turbos. If anyone has a k04-2x series turbo they can measure and verify which is correct i would appreciate it. Thanks!

      IIRC the inlet is almost exactly 1.75" and that would sort of suggest the inducer is ~44mm? Then the turbo outlet is ~2" or 49mm IIRC.

      I asked Pat at Forge Motorsport a few things about their outlet hose as I was trying to figure out why I needed it over a standard 90º elbow. Here's what I asked:

      Quote, originally posted by Ben Harper »
      I am interested in a few different silicone hoses and would like to ask a few questions. First, I am looking for a hose with the same dimensions as:

      http://www.forgemotorsport.com...225TH

      But I am not about to pay $90 for it. I don't really see what the difference is between that hose and your reducing coupler:

      http://www.forgemotorsport.com...63-51

      The dimensions are simple but I don't know how long your legs are for the reducing elbows. It says 100mm from 13-57mm and 125mm from 60mm up - but my hose (63mm on one leg, 51mm on the other) would fall right in between those numbers. So would one leg be 100mm and the other be 125mm?

      Pat wrote this in response...

      Quote, originally posted by Patrick Robles »
      There are several differences between the two hoses, firstly but least important are the sizes and a slight difference in angle. The TT specific hose is ~65mm on one end and ~54 on the other, the 63-51 could work but it would be a stretch, literally. But more importantly the TT hose is floro-lined and Nomex impregnated, this is necessary for the heat and the amount of oil that the hose will see. The production cost on the 225 hose is 5 times greater than the normal reducing elbow. Unfortunately due to the conditions being outside of the acceptable operating ranges of traditional silicon we cannot honour any warranty claims on a standard reducer used in that application.

      The reducing elbows will have a leg length on both side appropriate for the larger of the two ID dimensions. So in the case of this hose 125mm on each end. This will make the standard hose a good bit longer on the small end as compared to the TT turbo hose.
