BMW Internal Engine Parts for BMW 3 Series E30 (1984-1991)

Kolbenschmidt (KS) rod bearing sets are engineered to deliver exceptional performance and reliability, making them an ideal choice for demanding automotive applications. These sets are designed to provide maximum load-bearing capacity, ensuring optimal engine function under heavy loads and high-stress conditions. The use of advanced materials and coatings contributes to anti-seize properties, reducing friction and wear for extended durability.

Manufactured with precision, KS rod bearing sets feature aluminum-tin sliding material combined with an innovative aluminum-zinc-bismuth alloy. This alloy, with bismuth replacing lead, enhances performance while meeting modern environmental standards. The manufacturing process involves casting aluminum strips on-site, followed by carefully coordinated rolling and annealing processes to create composite materials with superior strength and reliability.

One of the standout features of KS rod bearing sets is their innovative coatings, which play a crucial role in ensuring optimal running-in behavior and long-term continuous operation with minimal wear. These coatings range from galvanic films applied electrochemically to electro-physically deposited sputter layers in a high vacuum, as well as synthetic anti-friction coatings. This comprehensive approach to surface treatments enhances performance and longevity, making KS rod bearing sets a top choice for OEM applications.

One of our most popular items! We have been selling our S14 stroker kit since 1993. Since then we have sold HUNDREDS of this exact kit, and have received incredible feedback from our customers. RELIABLE Horsepower is our goal. Our E30 M3 2.5L Stroker kit uses factory BMW Evolution III parts to convert the stock 2.3 liter engine into the Evolution III 2.5 liter engine. Increasing the displacement and raising the compression yields much more torque: +50 ft/lbs @ 4000 rpm. With a stock head our 2.5 kit will make over 225 hp.

Our kit includes everything you need to convert your 2.3L into a 2.5L. We highly recommend upgrading the intake and exhaust system to allow larger 2.5L engine to breath. Call for more details and for "custom" packages. We can set you up with any other engine components you may want to replace (tensioner rails, chain guides, oil pump, etc) at the same time. For your benefit, we carry all these items (and at a great price).
