If the consumption is too large, then you need to buy new piston rings. But if at your M3 is high oil consumption, then a problem in valve stem seals.

Nevertheless, S54 continued to install on Z4M till 2008.Ĭompare with BMW M54, on S54 there are no big problems with engine oil consumption. The S54 installed on M3 E46 till 2006 then there was new M3, with absolutely another V8 motor – S65.
It increase the power of 3.2-liter motor to 360 horsepower at 7,900 rpm. CSL differs from usual S54 by improved intake system, aggressive camshafts (duration 288/280, lift 11.6/11.6 mm), exhaust valves and the lightweight exhaust system. This car produced in 2003 in limited edition. The most powerful modification of S54 installed on the lightweight version E46 M3 CSL. Two additional catalytic converters cased difference in 10 horsepower between US and Euro versions. Its power decreased to 325 HP (Euro version) and to 315 horsepower (US version).ĭifferences between S54 M3 and S54 Z3M consist in the changed intake manifold and air filter housing. Differences between US E46 M3 and Euro version consist in two additional catalytic converters. All these changes helped to increase the power of the engine to 343 horsepower at 7,900 rpm and a torque 365 at 4,900 rpm.Į46 M3 engine with power of 333 HP produced for North American. The electronic control unit of S54B32 – Siemens MSS 54. The stock size of fuel injectors of S54 – 247 cc/min. Individual throttle bodies still used on intake. Valve clearances are following (cold engine): inlet 0.18 – 0.23 mm, exhaust 0.28 – 0.33 mm. S54 still haven’t hydraulic lifters so every 30,000 miles of mileage (50,000 km) you have to adjust valves. There were following changes in cylinder head: improved continuously variable valve timing system Double-VANOS, used new cast iron hollow camshafts (duration 260/260, lift 12/12 mm) and decreased weight of the cylinder head. The pistons are cooled by oil spray nozzles. Also applied reinforced forged connecting rods (length 139 mm), new high compression pistons (CR=11.5), their compression height 32.3 mm. Cast-iron cylinder block of this engine has been improved: increased bore to 87 mm, forged crankshaft with a stroke of 91 mm and with 12 counterweights. New S54 inline-6 based on the European version BMW S50B32.

This motor is the flagship of series M54 (which included M54B22, M54B25 and M54B30). Neither the motor for North America not for Europe used in this model. In 2000 there was next BMW M3 in E46 body. Limited to just 10 examples, the Strassen Version was priced at 250,000 Euro.Normal engine operating temperature, ☌ (F)īMW S54 engine reliability, problems and repair The road going M3 GTR also featured a fully upholstered interior but retained many of the composite components. To make it more usable on the road, the racing engine was detuned but still produced between 350 and 380 bhp. Crucially, it also featured the V8 engine that was found in no other production BMW. In order for the car to be homologated, BMW announced a production run of a Strassen Version or Road Version. All of these components were crafted in exotic composite materials to bring the weight down to the regulation minimum. Further changes included an aggressive aerodynamics package with a deep front air-dam and sizeable rear spoiler.
One of the advantages of using the considerably shorter engine was that there was additional space ahead of the V8 to mount the radiators at such an angle that the air could be vented out over the engine cover and did not have to go through the engine. The new engine, code-named P60, was mated to a six-speed sequential gearbox. With the mandatory intake restrictors in place, it produced around 500 hp according to BMW. This was an all-aluminium unit, featuring a 90° bank angle and displacing just under four litres. Instead, the BMW Motorsport engineers decided to create a compact and lightweight V8 engine from scratch to power the new M3 GTR. Experience with previous M3 competition cars, however, had revealed that the straight six used in the M3 road car would not provide a suitable basis for a competitive racing engine, despite working so well in the road car. To underline the sporting credentials of the newly introduced E46 series M3, BMW created a new competition version to compete in the American Le Mans Series (ALMS) from the start of the 2001 season.
