Has anyone bored/stroked their a4?
I have googled and found nothing. Is it possible or are the cars still to new for people to break their warranties?
just bought my Audi after driving a mustang for 10 years.
Thank you,
Jason

The EA888 family has a long history, including in things like GTIs that might be modded more frequently, so I suspect there's someone somewhere who has looked at just about every type of mod for those engines, at least for the earlier generations.
That being said, with turbo engines, I suspect the most popular mod is a tune, e.g. from APR.

That seems like a way more difficult way to get more power out of a 2.0t engine. The way most people go about this is with a tune and then bigger turbos. APR has several levels of tune to accomplish this. And yes, you’d most certainly void the warranty doing so, so more often than not people modding their engines have older gen Audis or VWs.

The purpose of boring and stroking an engine (besides the fun of tearing it down and reassembling) is to increase the displacement to process more air-fuel mixture. This is much more easily accomplished on a forced induction engine by a tune or a larger turbocharger and the gains are much greater than you would ever get by a simple bore/stroke increase. Also, all new engine cylinders have a very highly engineered crosshatch honing to control oil consumption. It is unlikely that any non-OEM shop could match this crosshatch.

I don't know about the E888 but older Audi engines like the 5 cyl 2.2l could easily double the boost (from 14 psi to 28 psi) and live long, happy lives. Those cars had manual tranny's and first gear was a little weak so you could not drop the clutch without slowly doing damage to the cogs. I suspect the B9 DSG tranny will also have problems handling large increases in torque. Someone on line here can probably comment on the torque handling capacity of the DSG.
