 ==Engine Swaps==
 While every E30 is a sublime driving machine, the desire for more power leads many to look at their options. Since many E30 engines are unsympathetic to "tuning" without spending serious cash, many owners look towards swapping their old engines for alternative BMW units. If you're thinking about this, take a look at the current option of [[Engine_Swaps|engine swaps]].

		+	Your petrol motor needs an electric motor to get it started. This motor spins the engine up to the speed needed for normal combustion to work - once those are happening, the starter will disengage.
		+
		+	The starter for all E30 engines sits on the intake side of the engine, and is bolted to the gearbox. It has direct heavy-duty wiring to the alternator and battery, and grounds through the engine block to the car chassis. It is triggered by wiring directly from the ignition switch.
		+
		+	Starters are specific to each engine, because the gear teeth of the starter cog has to match the teeth on the engine flywheel. What's more, there is a difference between early and late M20 starters due to a change in flywheel in 1987.

 The main body of the engine is surrounded by ancillary components to supply fuel, air and spark, as well as devices for lubrication and cooling. The overall engine is controlled by an engine management system.

 The exhaust allows all of the waste gases to leave the engine; if you didn't let that happen, the engine would explode like a pressure cooker. But it's not just a simple case of letting off steam; the pressure and speed with which these gases leave the system is crucial for smooth engine running.
-A wide range of exhausts were fitted to E30s; two-and three-piece units, twin or single pipes, with or without catalytic converters and therefore with or without [[Lambda]] sensors. There are also a variety of aftermarket components such as improved exhaust manifolds and "tuning" backboxes to give a distinctive exhaust note when driving.
