The best solution for 24v Swapped E30's using an M50, M52, S50, S52US, S54, or Euro S50 Engine with the E34 525i M50 oil pan! The Achilles Motorsports Oil Pan Baffle was designed and manufactured to be used on racing, high-performance track, and street driven cars. Each baffle is precision laser cut from .090" heat-treated aluminum then hand-assembled and test fit to ensure accuracy and ease of installation. Achilles Motorsports' baffle design incorporates dual trap doors and a unique oil deflector that prevents oil from splashing out of the sump under hard braking. Together, these help minimize the sloshing of the oil inside the oil pan and keep oil accumulated around your pickup tube. The factory BMW oil pan doesn't do a very good job of keeping oil accumulated around the oil pick-up tube in high g-force situations. By keeping oil accumulated around the pickup tube you can eliminate the costly loss of oil pressure and potential damage to other vital engine parts commonly caused by high g-forces from hard acceleration and braking and high-speed cornering. Professional welding is required for installation!

Achilles Motorsports' S54 Swap oil pump upgrade kit is designed to work with late-model M50/S52 generation oil pumps. This is a typical conversion when retrofitting an S54 engine into a chassis such as an E30 or E34 that requires the use of a front sump oil pan. This kit can also be used to upgrade the Euro S50B30 3.0L Single Vanos engine oil pump to the later generation pump utilizing a higher volume pump. The ULTIMATE SOLUTION for your S54 Swapped car offered by Achilles Motorsports! Achilles takes their oil pump shafts to the extreme, using only the toughest materials and heat treatment processes to ensure optimum strength. The core of this kit is a hardened Chromoly shaft that is centerless ground to ensure absolute trueness. The shaft is engineered with an exclusive square key lock system that not only prevents the gear from ever spinning on the shaft but also adds strength to the area to which the gear mounts. Achilles Motorsports then replaced the pesky oil pump nut with an extended length bolt that is EDM drilled for safety wire to properly secure it for all conditions. Don't wait for your oil pump to fail and leave you stuck with costly engine repairs!

Your oil filter is your engine's primary defense against internal wear. By capturing metal shavings and debris, it prevents contaminants from grinding against sensitive moving parts and causing premature failure. Don't settle for inferior protection; these high-quality replacement filters ensure your oil remains clean and your engine stays "full of pep" for the long haul. Each filter includes the required sealing O-rings and washers to ensure a professional, leak-free service. For even better protection, pair this filter with a magnetic drain plug to trap metallic debris at the source. It’s a simple step that guarantees your engine remains fresh and properly lubricated between every service interval.
