Hmmm spend a ton of $$$ now, or wait for next-gen Z with direct injection?

I think Toyota employs an additional upstream injector to deal with this, but most don't. Pics of the VW 2.0 FSI and the Porsche Cayenne have been ugly.. Careful what you wish for.

Here's a pic of the newer VW/Audi 2.0 with direct injection (mileage unknown):


Here's a shot of a friend of mine's VW/Audi 1.8T (the engine that preceded the 2.0) with conventional injection, use of good gas, at 125,000 miles..
