add a turbo or a supercharger? How would you lower the compression ratio? is it just pistons and rods? just wondering how these tuners are going to fix up these cars.

Dished pistons would lower the CR, as would adding a thicker "gasket" (not sure of the actual term in this case).

I've seen posts on AW claiming that the gasket solution can be problematic; no personal knowledge of the issues, though.

It's going to be really expensive,whatever they do.

where did you find 11:1? Is it a 4 or 5V per cylinder?

That's good to know, although I am betting that this engine is sorta like the 12V in the A4. Only one or 2 production years until they get the final production engine which will probably hit USA later next year or 2004.

My take is after they finished the proper engine and get rid of this '12V' temporary motor, they will have the 4.2 FSI generating 340 or more US spec (92-93 octane) Hp with about 12:1 compression ratios.

Maybe these first builds are the ones to buy this time because they are the reverse of the '12V' - more tunable than a N/A FSI soon to come later.

I think I can fit a supercharger in there somewhere

wow, just noticed that it holds 11 quarts of oil

maybe a supercharger with a new hood.

hopefully PES or APR can do something magical to this engine. the S4 4.2 engine isnt the same as the RS6 engine?

11 x ~5$ quart and filter...that is one expensive oil change!
