ACE Racing Engines

At ACE Racing Engines, you're buying into a lasting relationship, not just getting a high performance, precision engine. Stef and Laura (Benny too!) have a fundamental interest in your program, not just your money.

I started working with Stef mid-spring in 2022 to build a solution capable of some records our car is capable of now. I took this same approach with 4 other top-tier LS builders. Money was the last of our considerations. Having a capable platform was paramount. My first contact for each was exactly the same email, detailed and precise. It drew the immediate attention of two builders, but Stef is THE only one that resonated with me with more intelligent questions, not immediate canned solutions. This is by no means a comparison as to the other builders' proficiencies, because we don't run their product. What I do know is throughout the entire process, conception, build adjustments, wire transfer, timeline development, partnering with our Converter and Turbo Vendors, CA-FL delivery, through final billing, this was THE most "taken care of" I've ever felt. There just could not have been more transparency to the entire process!!

Just like other builders, Stef faced uphill battles with product availability. However, while I watched other competitors struggle, Stef and Laura seemed to find what they needed in a timely manner, and were fully supported by their vendors as well. To me, that signified something larger than JUST being a good engine builder. That signified that EVERYONE supporting their business was interested in their success as well.

Stef is like a kid on Christmas waiting for your results ... He's not only concerned about his product being up to the test, but he's constantly looking for feedback on how to make it better. I cannot overemphasize the fact that this feels like a bi-directional partnership. Now here's my caution. Don't go there looking for a Social Media discount as Stef enjoys competitive mindsets, not people looking for personal glory.

My final testimony: I feel confident these guys will soon be in a place no other engine builder can compete with on process, precision, performance and price. I'm so confident that we're already looking to have a billet LS engine built for the 2024 future of The LawnDart³!! Take my MONEY!!

Steff went above and beyond. He rebuilt my 427 LS fast. Awesome communication. Pictures daily of progress. This isn't a 1,000hp build either...my LS pushes 2500hp and we beat on it hard. Thanks ACE RACING ENGINES Steff and Laura are truly stand up people!

Stefan built a 2180cc air cooled customized engine for my 1964 restored VW bus. Stefan communicated with me during g the entire process and was transparent on any issue (mostly supply chain issues during Covid). In the end I could not be happier with the performance of my engine, Stefan’s follow up and support. I highly recommend Ace-Engines. Chris S. Manhattan Beach

Stefan is a stand up guy very willing to spend time to talk about what works and will not work. Big props to ACE Racing Engines, had some initial problems with the heads and if it wasn’t for his OCD with measuring everything it would not of been detected.

Ive just installed my awesome all new 2332cc turbo EFI motor, built by Stef at ACE. Stefs attention to detail, care and measuring of all clearances during the assembly of the long block is something that's rare to find these days. The advise given by Stef when choosing components really shows an expert in his field. If you want a hypo V8 or Flat4 built then give Stef a call. You wont be disappointed. Cheers Stef.
