BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades. Kit Features and Contents: Vargas Turbo Crank Bolt Capture Vargas Turbo Crank Seal Plate OEM Accessory Belt OEM Belt Tensioner & Idler Pullies Liqui-Moly Longtime High Tech Engine Oil (5w-30) - 7 Liters OEM Hengst Oil Filter OEM Oil Filter/Cooler Housing Gaskets TMS Oil Change Sticker Genuine BMW Full-Strength Coolant - 1 Liter Looking to go even further and upgrade your Crank Hub as well?

CTS Turbo is excited to announce the release of our latest Stage 2+ aka the “RS” turbocharger set, designed specifically for the BMW S55 platform. This kit builds on the success and knowledge of the previous turbo projects we have made and incorporates new technology to optimize performance and maintain factory fitment. Our engineers utilized transient flow analysis and flow bench testing to optimize the twin-scroll turbine housing while maintaining stock fitment, stock location, and stock wastegates. This allows for the use of any stock fitment downpipes, intakes, and charge pipes. The result is an impressive 808whp on a built engine with supporting mods. You can simply transfer your factory wastegates, high-performance downpipes, intake, and charge pipes during the installation. No custom parts are needed and all factory installation hardware and gaskets are used! The kit features complete brand-new turbochargers and large inlet pipes. No need for cores to be sent in or purchased. Each turbocharger is VSR balanced to exceed OE tolerances with upgraded heavy-duty bearings and thrust washers. We supply reinforced silicone inlets, that are compatible with any intake system. These inlets will not collapse or deform under vacuum. Our turbochargers are designed to move a lot of air at lower boost levels, which means you can make some serious power without over-speeding the turbos, which means reliable performance. Optimal boost levels are 24-25psi with approximately 85-88% WGDC. This must be confirmed by your tuner and adjusted, depending on your build. Features: Complete brand new turbocharger; no need for core to be sent it or purchased Bolt-on journal bearing CHRA with HD bearings, turbine shaft diameter increased by 0.5mm and thrust surface increased by 2mm Billet 8 blade compressor wheel, 47.4mm inducer, 58mm exducer with 63.10mm extended tip design 9 blade Mar-M 246 Superalloy turbine wheel, 52mm inducer, 45.6mm exducer, high-flow 316 stainless steel exhaust housings and wastegate components VSR Balanced to exceed OE tolerances Wire-reinforced silicone turbo inlet included Compatible with factory installation hardware (not included) Compatible with factory wastegate actuators (not included, use your original wastegate actuators) Fitment: 2015 – 2020 BMW M3 and BMW M4 with S55 engine (F80, F82, F83) 2018 – 2021 BMW M2C and BMW M2CS with S55 engine (F87) NOTE: Installation and tuning must be performed by a qualified professional. Wastegate actuators MUST be calibrated using ISTA+ software before tuning.
