Query: Not Performance Projects but Maintenance Projects

If you are looking for a book about Bmw e36 maintenance projects this book is for you! But if you are looking for performance projects that transform your stock car in a power beast, well this book has little about it, it covers little about CAI, chip, turbo, hp gains and torque, there's is nothing about big bore throttle, sport header, flywheel, pulleys, fan delete etc the mods you usually would do to bring your 192 bhp car to a 250 bhp monster. It covers little about others models.
