Borowski Race Engines, Inc., Rockdale, IL

Custom CNC Engine Builders for Street, Race, Restoration & Marine. Est. 1968.

Our state-of-the-art CNC machinery is the most advanced available. The staff boasts more than 100 years of collective experience and includes accomplished racers and crew chiefs. We are not your usual cookie cutter, generic engine-in-a-box guys, but rather a full custom shop with a focus on American muscle and a side specialty of SCAA spec Miata engines. We marry our engines of all types with Whipple superchargers, Prochargers, Bullseye turbos and nitrous kits for an incredible range of power and performance options.

Dart Machinery has long been our preferred aftermarket block supplier and is the platform for our HellFire® line of semi-custom LS type engines. In our opinion, Dart’s LSNext® blocks are a game changer. The differences relative to a factory LS block are visually obvious. The advantages of these blocks allow us to push the envelope even further for more power and reliability. Our cutting edge LS engine technology has frequently been featured in Engine Labs magazine.

We focus on a limited number of top-quality parts vendors and maintain inventory of the key parts we use. This allows us to sell high-end parts, engines and assemblies on short lead times whereas other engine builders or parts suppliers may be waiting six months for back-ordered products. Our vendors have been carefully vetted, often with on-site visits such as shown in these videos shot at Callies and Bullseye. Our hand-selected manufacturers work closely with us and frequently provide us with their newest technology for market introduction.

In the ads below, you will see everything from bare blocks and supercharger assemblies to representative complete and fully dressed builds that can be ordered and shipped to you. If you don’t see what you are looking for, please give us a call at 815-725-2727 or send an email to ken@borowskirace.com
