Looking for an optimal oil cooling system for your S54 swapped E30 or E36? Look no further than CSF's solution for the S54 engine. Drawing on their extensive experience in designing high-performance BMW cooling systems, CSF has designed this S54 swap-specific radiator to get rid of the guesswork involved in setting up a cooling system in an E30 or E36 chassis.
This system is designed to cater to the specific requirements of the S54 engine, which requires a more robust oil cooling system than the E36's S52 or E30's S14. CSF's S54 oil cooling system offers a factory-style fitment, allowing two race-spec oil coolers to be installed beneath the radiator. The radiator itself is slightly shorter to accommodate the oil coolers. With CSF's system, you can rest assured that your S54 engine will receive the oil cooling it needs to perform at its best. Note that this radiator and oil cooler combination is also suitable for S50 and S52 setups. The radiator also includes a custom-designed cover plate that allows for optimal coolant overflow line placement, which is concealed for an OEM+ appearance.
In addition to the oil coolers, CSF also includes mounting brackets for an electric fan conversion, allowing you to maximize the performance benefits of an electric fan. These brackets are designed to fit a single 16-inch SPAL Fan (not included). While it is possible to retain a clutch-type fan, an electric fan conversion is easier and provides additional performance benefits.
