I cant afford a whole 97+ car so im curious how a swap would work out...any comments would be appreciated.

<b>Jetta III 1.8t by <a href="http://momentummotor.com" target="_top">Momentum Motorsport</a> in Port Coquitlam, BC.</b>

Check the current <i>(October)</i> issue of European Car magazine. It features an "Oh my God that guy has way too much money" M3 built by Momentum Motorsport, as well as an article on a Eurosport (Anaheim, CA) Rabbit with a 1.8 20v engine. (no "T"). The article states that the current 1.8t engine in fact uses the same old 2.0l 16v short block, but with a 20v head. There was a <a href="http://www.a4.org/forum/m/performance/574.phtml">post</a> in the Performance Forum that said the same thing.

I hope this helps.

Yes, this is quite a straight forward swap using the Audi A3 components, as sourced from a few importers. Using the longitudinal A4/B5 components causes a lot of fitment issues.
However, the article did not say that the clock was the *same* 2.0l 16V or 8V that VW has been using for years, it said that the 1.8T block was *similar*. You cannot bolt a 1.8T head onto either of those blocks. There are a few coolant passages that overhang. The block is similar in the aspect that it has all the provisions for mounting in a variety of chassis.

Hey Todd,

Thanks. I know very little about the actual block, that was what I derived from the article. :-)

The engine in that pictured Jetta 3 actually came from an longitudely mounted A4, and you're right, fitment problems. That's why the intake manifold from the 1.8t Beetle was used.
