V8 ENGINE BMW Specialists

V8 ENGINE Specialist are your BMW technicians in Sandton. We are a company that was established in 1992 specializing as a well known engine reconditioning and service centre. With over 30 years of experience in engine building and specialised motor engineering services we offer you excellent products and service uncompromised by quality.

The business was initially started by building various combinations of stroker motors such as the BMW M10, M20, M30 and M50 engines.

BMW's M10 engine was one of the first stroker motors we built which is a straight-4 cylinder SOHC engine, produced by BMW from 1962 to 1988 with displacements ranging from 1499 cc to 2200 cc. Over 3.5 million of these engines were produced by BMW AG.

The turbocharged BMW M12 engine was a 1500 cc 4-cylinder Formula One engine, a derivative of the M10 engine, capable of producing over 700 kW and used to power the cars of Brabham, Benetton and Arrows and won the F1 world championship in 1983.

The M20 engine, is a straight-6 cylinder SOHC 12 valve engine driven by a timing belt and was produced from 1977-1993. The larger capacity motor was a straight-6 cylinder M30 engine manufactured from 1968-1994 and was produced alongside the M20 engine.

The M20 engines powered the BMW E21 and E30 3-Series cars including the E12, E28 and the E34 5-Series until 1993, when it was replaced by the BMW M50 engine, a DOHC motor which features a twin cam alloy cylinder head with four valves per cylinder and VANOS, introduced in 1992.

V8 ENGINE embedded its production line with some of the first stroker engines built, of which were later used by a handful of prominent performance engine suppliers throughout South Africa for their customer base. An array of steel crankshafts were stroked. 

The process involves specialized welding of the Big End journals, enlargening the big ends dramatically and then grinding them to std size, off-setting the centres, resulting in an increased stroke which dramatically increases the torque output of an engine.

Crankshafts were then heat treated, a process called ‘nitriding’, which diffuses nitrogen into the surface of a metal to create a case hardened surface. This heat treating method is predominantly used on steel, aluminium, titanium and molybdenum metals. There are three main methods used for nitriding, namely, gas nitriding, cyanide salt nitriding, and plasma nitriding.

Once the stroking and case hardened is completed, the engine assembly process would begin by fitting the crankshaft. An increase in stroke meant that the standard pistons would need to be changed or pistons be machined down to a suitable compression or deck height, including the machining of valve pockets.

Different compression heights were used to determine specific compression ratios for each motor, including custom made pistons or the use of a 'pop-up' or dome type piston. Compression ratios are relevant to the type of fuel being used and more than often, is often over extended by the engine builder imposing a higher compression ratio than what is required, resulting in premature detonation.

Today V8 ENGINE specializes in building naturally aspirated, supercharged and turbocharged V8 petrol engines for the BMW X5, M3, M5, 540, 645 and 740 vehicles.
