|The E30 M3 is the BMW Motorsport-developed version of the E30 3 Series. Its S14 four-cylinder powerplant is a further development of the M10 unit and was chosen because of its compact dimensions. The chassis is based on the basic E30 3 Series design but has been thoroughly reworked by BMW Motorsport in every significant area. The reshaped body shares few panels with other E30 3 Series models.What makes the S14 engine unique?
The E30 M3’s S14 engine was designed for racing applications and is therefore compact and high-revving. It combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments.
