The A4S was truly the pick of the bunch; a well thought out, simple, but superbly executed engineering exercise. A tubular exhaust manifold was fitted to all the modified engines, and if the customer wished, the four-speed manual gearbox could be replaced with the close-ratio five-speed which compensated for the narrow power band of the tuned unit.

2010年12月19日 · Anyone here know what the specs were for an Alpina A4s engine and the output it generates? I tried searching the forum for feedback on Metric Mechanic engines and reliability.

2014年11月25日 · When I had my A4 rebuilt, the rebuilder bored the 42mm part to 45mm. That necking should increase performance. It certainly increases charge velocity.

2012年4月22日 · I notice there's a difference with the last letters on the trans part number for different build date. Mine was build 10-96. And I find a lot of trans from 97 but they said its for 02-97 build date and up. They are same A4S 310R trans, so what's the difference and what will be the problem if I use a later build date?

195 bhp, 1,998 cc OHC inline four-cylinder engine with fuel injection, five-speed manual G transmission, independent front suspension with coil springs, McPherson struts, anti-roll bar, and telescopic dampers; independent rear suspension with coil springs, semi-trailing arms, anti-roll bar, and telescopic dampers; and four-wheel ventilated disc ...

This 1974 BMW 2002tii was modified by Alpina to A4S specification and is powered by a fuel-injected 2.0L inline-four mated to a five-speed manual transmission.

This 1974 BMW 2002 Tii Alpina A4S is an example of what might be the best version ever built. With four-cylinder engine producing 195 hp, it was far more powerful than the stock version, modified by Alpina and fully certified.
