Hi bros sis, my dad used to own this baby monster for about 15years...I never forgot e way it performed in many runs up North and Eastern coast of Peninsular Malaysia, going through the trunk roads with oncoming trucks..buses...watching the North South Highway being built...
if anyone sees a similar little monster around or something, please give me a heads up as I am interested in giving him a little surprise...and...I'll like to teach myself how to drive a stick again -_-
190 E 2.3-16 & 2.5-16 "Cosworth"
Back in the late 1970s, Mercedes competed in rallying with the big V8-powered Coupés of the R107 Series, mainly the light-weight Mercedes 450 SLC 5.0. Mercedes wished to take the 190 E rallying, and asked British race car engineering company Cosworth to develop an engine with 320 bhp (239 kW) for the rally car. This project was known as project "WAA" by Cosworth". During this time, the Audi Quattro with its all wheel drive and turbocharger was launched and made it apparent that the 2.3-16v would not be competitive. With a continued desire to compete in high-profile motorsport with the 190, and also now an engine to do it with, Mercedes turned to the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) motorsport series instead. Cars racing in this championship, however, had to be based on a roadgoing model. Mercedes therefore had to put into series production a 190 fitted with a detuned version of the Cosworth engine. This high performance model was known as the 190 E 2.3-16, and debuted at the Frankfurt Auto Show in September 1983, after its reputation had already been established. Three cars, only slightly cosmetically altered, had set three world records in August at Nardo, Italy, recording a combined average speed of 154.06 mph (247.94 km/h) over the 50,000 km endurance test, and establishing twelve international endurance records.
Engine
The Cosworth engine was based on the 2.3-liter 8-valve 136 hp (101 kW) unit already fitted to the 190- and E-Class series. Cosworth developed the cylinder head, "applying knowledge we've learnt from the DFC and BDA". It was made from light alloy using Coscast's unique casting process and brought with it dual overhead camshafts and four valves per cylinder, meaning 16 valves total which were developed to be the "largest that could practically be fitted into the combustion chamber".
In roadgoing trim the 190 E 2.3-16 produced 49 hp (36 kW) and 41 ft·lbf (55 N·m) of torque over the basic single overhead cam 2.3 engine on which it was based. The 2.3 L 16 valve engine made "185 hp (137 kW) at 6,200 rpm and 174 ft·lbf (235 N·m) at 4,500 rpm, the oversquare 95.50 x 80.25 mm bore and stroke dimensions ensuring that it revs easily up to the 7000 rpm redline". Acceleration from 0-100 km/h (62 mph) was less than eight seconds, and the top speed was 230 km/h (143 mph).
US-Specification cars had a slightly reduced compression ratio (9.7:1 instead of 10.5:1), and were rated at 167 hp (125 kW) @ 5800 rpm and 162 lb·ft (220 N·m) @ 4750.
The roadgoing version of the engine was reconfigured with reduced inlet and exhaust port sizes, different camshaft profiles, no dry sump configuration and Bosch K-jetronic replacing the specialised Kugelfischer fuel injection. These changes helped bring power down to the required 185 bhp (138 kW) specification, but still resulted in a "remarkably flexible engine, with a very flat torque curve and a wide power band". The heads for the engines were cast at Cosworth's Coscast foundry in Worcester and sent to Germany to be fitted to the rest of the engine, parts of which were different from the standard 2.3 including light pressed alloy pistons, and rings designed to withstand higher engine speeds, whilst con-rods, bearings and bearing caps were found to be strong enough as standard and left unaltered.
