While we're on engine specs I'd thought I'd share something I just shared with the Brikskodians as well...
EA 111
The EA111 series was introduced in the mid 1970s in the Audi 50 and later the VW Polo. It is a series of water cooled three- and four-cylinder gasoline and Diesel engines in a variety of sizes. The overhead cam engine features a crossflow cylinder head design and directly-driven auxiliary units. The exhaust side is in driving direction.

122-170 hp 1.4 TSI
Announced at the 2005 Frankfurt Auto Show to be used in the Golf GT, The 1.4l Twincharger is a TSI engine with a turbocharger and a supercharger in combination. Its downsizing leads to economy, with 14% more power than the 2.0 FSI but consuming 5% less fuel. The mechanical compressor operates at low engine speeds below 2400 rpm to increase low-end power, the turbocharger engages at middle revs, a clutch disengage the supercharger which will then be bypassed once the turbocharger reaches sufficient speed to provide boost above 3500 rpm.
In 2007 Volkswagen announced the 90 kW model which will replace the 1.6 FSI 115 hp (86 kW) engine. This engine differs from the 103 kW and 125 kW models in several ways. It is turbocharger only and has water-cooled intercooler to reduce charge time. The engine has reduced frictional losses, optimized camshafts, new intake port and new high-pressure injector valves. It is also 14 kg lighter than the 125 kW model, all to improve fuel economy and reduce emissions.
