Volvo K24 turbo in audi application.

[Neacail]

Has anyone found a compressor map for this turbo?

I just used the standard CHRA Volvo unit, then a standard k26/6 from the Porsche. Bolted them together, no problems.

Did you use the Porsche exhaust wheel though? The k26/6 housing is the bolt on hotsite, and I know some people have machined k24 housings to fit, I was just wondering if anyone had fitted the larger turbine wheel and housing.

[byd1380]

It ended up being K26/6 on mine

[paradox11235]

So did anyone ever try building a porsche/volvo hybrid (k26/8 wheel and housing I think was the idea)?

For reference

Test fit with the non v band housing, clocked to clear the oil line, not going to work, straight into the engine mount sheet metal.







V band housing with the v band cut off with a hacksaw, markings filed off, clocked to clear the oil line with the internal bpv still fitted.

Looks doable with a 45 or 90 silicone elbow coming forward to the intercooler.

I couldn't find a v-band either, I got it machined off and just fitted the silicone hose straight on. I have sold my car to friend, but actually drove it today for the first time in a while, very usable turbo. I was driving along and asked "is that still 4th" shocked at the torque. I had the same comment from a friend of mine when in it, he had a 360lb/ft B5 S4.

Ok, I couldnt find one so just got a normal outlet coldside for £20.

V band is nice though.

The hose adapter came from an outfit called "IPD" that sells performance goodies for Volvos: http://www.ipdusa.com/products/9318/...v70r-2004-2005

The v-band clamp itself was not easy to come by! For some reason IPD doesn't sell it. You can get it from Volvo but it's very expensive - I seem to remember it's over $100.00. What I ended up doing was contacting the guy I got the turbo from (who was parting the whole car) and bought it from him.

[andy10v]

Ah, I got you, I am planning one upgrading/moving the oil cooler to the front grill with the mg setup as its cheap/good upgrade.

Where did you get that V band adapter? Or can you just use a normal V band?

[elaw]

That looks nice!

I think I'm going to end up with something similar to your second setup. I've ordered a couple of flanges with AN fittings, and some AN hose and fittings to connect them together.

I've decided I don't like the idea of clocking the compressor housing way around, and here's why:

The outlet on this turbo's compressor is already longer than on the stock K24, and with the adapter on there it's longer still! Rotating the compressor housing enough for the stock oil line to clear the BPV would put the outlet way behind my oil cooler and I think plumbing from that location to the IC would be a nightmare.

I know one obvious answer would be to ditch the adapter, but it's got a tapered inside that should help performance by providing a smooth transition from the ID of the compressor outlet to the ID of the hose, so I want to keep it if at all possible.

On my car i had the oil pressure line welded-extended, but after that it was changed to custom oil line with 1/8 NPT thread on the turbo side. Rest of them are AAN stock lines. Ofcourse the turbo outlet is welded and internal bypass is blocked off.

[andy10v]

Intercooler is currently in under a pile of **** in the boot

But will be going back in its place on the front, not ideal turbo outlet location, but I think I can make it work.

I think that is why Dave's is cut and welded. Other people have just fitted/made longer lines.

Here is a better photo to show the modifications made to the cold side of the turbo, you can see the block off plate for the internal BPV and also that the outlet was shortened to have the output in the stock Audi outlet location.

[elaw]

Yikes! That certainly takes care of the oil line issue, but it seems like the outlet is pointing in a direction that makes it hard to connect to. Where is your intercooler located?

[andy10v]

Glad you are making progress again.

To answer your question on motorgeek

I do have one question for those who have done this before: getting the oil feed line to clear the bypass valve on the Volvo K24 - is that a slight tweak to the line, or do you have to bend it within an inch of its life?

I clocked the coldside to clear the lines
