RichLV's UrS4

[RichLV]

Went to the garage, to take the turbo off. This is what I found:

Compressor wheel change inevitable. Turbine wheel fine though. It has a nasty radial movement, very nasty. And a barely noticable axial movement.


Hotside looks strange...

Also took off my fuel rail. Somehow people manage to even break those...

I have a replacement rail ready.

My backup ride while the big one is on maintenance mode.

Thanks Dave. I've seen these but the question was whether the plate can be bought somewhere or it has to be fabbed up?

2) What's with the blocking plate on the compressor housing?

That K24-7400 got me interested. I've been digging the web for some definitive information but I cannot find anything. So the questions are:
1) What figures can it make (with uprated rods)?
2) How can it be fit? Will a K26 housing from an old 10VT fit it? What's with the blocking plate on the compressor housing?

[RichLV]

How do you experienced people choose rods for your 20v miracle? I'm thinking maybe get a set of a bit beefier rods, just in case. Around 400HP and 550NM torque target.

First 3 listings are pretty nice. Price is affordable and it's in Germany so no additional taxes. What's the difference between I beam, H beam and X beam rods?

Maybe you will find the info you need in this thread http://www.s2forum.com/forum/showthread.php?t=74331

My classic URS4

Or maybe opt for a S6 C5... Can be gotten with a manual. 4.2 NA is probably the most reliable thing Audi has ever created. 340 HP should be enough. Not tunable without big mods though.

@quattrostyle, I meant advice on turbo upgrades. Either get a GT2871/KKK hybrid or opt for an RS2 K24-7200. Hybrid would be more sensible because Garrett parts can be easily sourced, which cannot be said for the old K24's. But that damn hybrid kit costs 1800$ on 034, and we have horrible taxes for importing stuff outside EU (+21%). I can get a new authentic RS2 turbo for like 1200 eur, but it's old in case parts are needed.

What about K24-7400 from a Volvo, is it a bolt on operation?

[quattrostyle]

Still need advice on turbos though.

I would think it is not hard to find a turbo in used but good condition on here?

Yep, it does not look fun. Alright I've changed my mind. Let's fix the old junker.

Hunker, RS6 C5 is V8 BiT, engine code BCY, 450 HP.

Fair enough, I was certain it's NA V8 Now that I know it's turbocharged I want it even more

I stand corrected. Even so, the engine has to come out of the car to change the turbos and this doesn't look like much fun:

Turbos? It's NA

[UrS4boy]

That's an S4 B6 V8 (or even later one). RS6 still has timing belt. It was the last engine before chains, ANK engine code (2000+).

What amuses me more is that Audi want both of my kidneys for a set of brake discs and pads for the RS6 C5...

[UrS4boy]

@Dave. Well everything that has been done on my UrS4 has been done with my own 2 hands (except welding). So I'd say I manage. Dunno about the RS6 though, it's rocket science compared to the old granpa C4.

Let me say this:
