Fitting 2.2 AAN to CQ with stock intake manifold

[kristjanr]

Hi everyone,

I’m currently planning an AAN swap into my Audi Coupe Quattro and looking into different options for the intake and cooling setup.

I have a stock S6 AAN engine and see three possible routes:

1. S2 over-engine setup – Requires quite a few original ABY/3B parts, so I’m not particularly interested in this route.
2. Wagner intake manifold – A nice solution, but quite expensive.
3. Pogo 70mm low radiator setup – This is the option I’m most interested in, as it allows me to retain the original AAN intake manifold.

What are your thoughts on the third option?

The car will be mainly used for street driving with the stock turbo, aiming for around 280–300 hp eventually.

Would the Pogo low radiator setup be sufficient for this kind of use? Are there any potential drawbacks worth considering?

Even if I added an auxiliary radiator, the total cost would still be roughly half the price of the Wagner setup. Another advantage of keeping the original AAN intake manifold is that I could retain the factory vacuum-operated cruise control, since there would be no need to relocate the throttle body.

I’d be interested to hear your thoughts.

Thanks!
