For the 1.8T the engine is similar but the mounting and ECU is different.
There is no chip for the 97 2.8 12V. It has a Hitachi ECU that is not programmable.
Mods are intake, exhaust, throttle body and MAF. Checkout the 12V forum on Audiworld . Look for postings by Usr4.
<BLOCKQUOTE type="cite"><PRE wrap="">Hi. does anyone know if the 1.8T turbo charger can fit on a 97 2.8?
Many things are possible, but whether there is any benefit, or
whether it is going to be cost-effective are entirely different
questions. I would think that there would be little point in adapting
the 2.8 (12 valve?) engine to take a single KO3 turbo.
<BLOCKQUOTE type="cite"><PRE wrap="">if not, is there a turbo for the 2.8?
There is/was a company (PES url:<A class=moz-txt-link-freetext href="http://www.pes-tuning.com ">http://www.pes-tuning.com </A>) producing a
supercharger kit for the 2.8 30 valve engine at a price of $5000.
Installation is likely to cost a fair few dollars on top.
<BLOCKQUOTE type="cite"><PRE wrap="">Also, is there a chip for the 2.8?
There are chips for the 12 valve and 30 valve engines, but you're
unlikely to get a significant power boost from simply chipping a
normally aspirated engine. However, you may gain a significant
improvement in smoothness and driveability. You would need to perform
other mods (including a change of camshaft profile) to gain much more
power. I don't know of anyone offering alternative profiles for the
<BLOCKQUOTE type="cite"><PRE wrap="">stock is 170 hp whats the cheapest and easiest way to get it to ~215?
170 hp? Yep, that sounds like the old 12 valve motor. Easiest and
cheapest way to get close to 200 bhp+ is to exchange your car for the
later 30 valve model (193bhp stock, chipping should get you over
200bhp), an S4 (250bhp stock in US/Canada), or a 1.8T (150bhp-180bhp,
depending on age/model, which can be chipped to 210bhp, or so).
