I just rec'd my 225 exhaust manifold and to my dismay, it IS NOT a direct swap for the regular K03 transverse manifold! The turbo mounting flanges are oriented 180 degrees oposite each other, so my original turbo won't fit!.
Here is a picture of it:

Has anyone here actually had a 225 factory K04 turbo in their hands? I would like to know if it uses the transverse type configutration or if it set-up like the A4 turbo? Photos would dispel the speculation that I have noticed concerning this subject so far.

Thanks,

The engines are designed for a 90* different orientation. That is why turbos come with different housings.

Yes I already know that. What I am planning to do is use the TT 225 exhaust manifold due to it's better flow, and complete the upgrade with a K04 and a TT 225 intake manifold. I already have a complete 1.8T transverse set-up with a K03, which is in a Passat B3 Syncro. The Syncro B3 strongly resembles the TT quattro in drivetrain lay-out, and this is why I prefer to use the TT 225 parts. What I need is some more technical info concerning the TT 225 factory K04 turbo and it's configuration. I also would like to know how the 225 downpipe & exhaust are laid out. This will help me determine how compatible these parts are.

Thanks,
Les

That does not line-up with a TT at all. The engine is turned the wrong way.

The TT is the same layout as the Golf/Jetta/New Beetle. FYI

The major differences between the A4 and TT K04 turbos:

TT is much larger
3 bolts vs 4 bolts to attach to manifold.
90* engine orientation difference

The 1.8T engine I installed was originally from a NB as well. The B3 Passats were made from '88-'94 and used either the 16V, 1.9TD or VR6. The B3 Syncro Passat used a G60 engine with a similar set-up to the Corrado G60.

Now, Everyone seems to mention the turbo using either 3 or 4 mounting bolts. I already have the TT225 manifold and it uses 3 bolts to mount the turbo. (See lower picture) So do all the K03 transverse & longitudinal set-ups. I believe that what you are refering to is actually the turbo exhaust outlet flange where the down pipe mounts. You can clearly see that the TT 180 in the upper picture uses the 4 bolt downpipe. I need to confirm WHAT the TT 225 uses as a down pipe and the turbo ORIENTATION in relation to the engine. Some people tell me that the TT 225 uses a 3 bolt outlet and exhaust pipe flange that is similar to the A4 longitudinal setup. I can't see how Audi would fit this all together in the tight confines of the TT chassis, hence the reason I am asking for clarification here.

when AWE and PES released their K04 kit for the TT . . .the K04 upgrade for the TT cannot be used on the A4. The bolt pattern will not match.

The downpipe for the 225 is the same as for the 180, except it is slightly larger.

You mentioned in a post on the TT forum that you have the ETKA cd, just check it, it shows the bolt patterns. They look the same to me.

The reason nobody has given you a firm answer in any forum is nobody has removed a turbo from a 225! Nothing to upgrade it to . . .yet.

A few people have done downpipes. Look for Emil on the TT forum. I think he has taken his turbo out of his 225TTQ.

The TT 180hp & 225hp DO NOT share the same design of down pipe, just as I had thought. If you look carefully at the image, you will notice that the 180hp turbo outlet exits facing rearward, while the 225hp exits facing to the passenger side.
I also looked at the bolt patterns and they aren't the same either. The 225 down pipe uses 3 bolts, and uses a 90 degree elbow, while the 180 uses 4 bolts and flows virtually straight back, just as in all other 1.8T transverse installations.

I have compared my NB engine, my 225 EM and as many photos and illustrations as I can find, and it leads me to conclude that the tt 225 Turbo RESEMBLES one from a Longitudinal installation, rather than one from a transverse set-up.

All I need is for someone to confirm what I am saying, preferably with some photos.

I realise that there aren't going to be many people who have removed their 225 turbo, EM, or DP. But there must be at least one or two who have done some porting, upgrading to an APR set-up, or Mods for racing?

Forgive me if I am comming off as a smart *ss, this is not my intention, I am just trying to gather up as much correct info as possible, and share it here as I go.

Thanks,

I understand your frustration. Unfortunately APR does not have a setup for the 225 as of yet. They are working on it and it should be out shortly. A few people are working on thjings privately but have not finished so they are not sharing as of yet.

I know some of the projects that are going on. Find SCTT in the TT forum and send him an e-mail with your question. He will be able to let you know what the turbo looks like in a 225, I promise.

It's people like you with your perserverance and resourcefulness who advance the art of tuning.

Thanks for the help, I'll post back when I some concrete info.
