brake upgrade, wheels and tires with it to match the performance) = big$$$

Or you could get a S4 - chip will put you @ 305HP
exhaust 320HP, downpipes 345-350HP, new turbos 420-450HP intercooler 500HP?

Big $ again... Audi's are expensive to modify!

 

I'm planning on getting an A4 auto (98 1.8t or 97 2.8) and thinking of doing the APR stageII(1.8t) within the first month or two. Considering that i had american (automatic)that did 0-60 in under 8sec and quarter mile 15.5sec almost stock, i was wondering what would it take for an A4 auto to be approx. 0-60 6-7sec and 1/4mile 15sec. flat or less. What kinds of mods would be for either 1.8t or 2.8. (automatic is the key word here) Thanks for your time.

 

We own both an A4 1.8T and a GSX ('96). I have chipped the 1.8T and the GSX is stock although one of our co-workers has a '98 with a lot of the usual go fast goodies - chip, BOV, exhaust, hybrid turbo larger intercooler so I have some idea what the 2.0T is capabable of.

At the upper end of the development for horsepower (in the vicinity of 350), I think the engines will produce similar horsepower curves. However the starting points are quite different. The 1.8T uses a rather small turbo intended to provide a V6 like low end. The 2.0T uses a larger turbo that doesnt deliver the low end torque but does offer greater high RPM potential. Next the plug compatible upgrade turbos for each have similar properties - the K04 on the 1.8T still isnt as good at the upper RPM end of the spectrum in terms of available boost and effeciency as is available for direct bolt in to the 2.0T engine. Once you get past the need for a direct bolt in replacement for the 1.8T turbo (new exhaust manifold, exhaust system, engine management software, charge air plumbing) the playing field levels out considerably. However getting there isnt as progressive as with the 2.0T. The change over of turbos away from the KKK series costs a bundle because of all the other manditory changes. It also costs a bit more than similar pieces for the 2.0T because the number of pieces sold for the Mistu engine in the aftermarket is much larger than the 1.8T market so far. This is likely to change somewhat as more VW's with the 1.8T mounted F-R like the Passat hit the road.

 

an S4 with chip exhaust and intake with mid 13 1/4mile times @ around 100+MPH

 

not a fwd 2.8
