The E3 Miata of RAMotorsports won the grueling NASA 25 Hours of Thunderhill E3 class with our engine. Congratulations to team owner Ron Alan and all of the drivers for completing 593 laps for a total of 1,779 miles. Check the official results on RaceHero.

We are so proud of Kyle Loustaunau for winning the 2014 NASA West Spec Miata Championship and then winning the Mazda MX-5 Cup shootout. It has been a great ride helping with his racing the last few years.

Congratulations Kyle you are now Mazda’s poster boy!

Nor Cal NASA Opener at Sonoma Raceway, California was an exciting one for Haag Performance.   Spec Miata racer Kyle Loustaunau won First Place both Saturday and Sunday February 9 & 10, 2013, with a time of 1.55.2 on Saturday and a 1.55.6 on Sunday.

Second Place went to Craig Evans both Saturday & Sunday with a 1.55.4 and a 1.55.6. Third Place went to Duncan Ellis. Congratulations to you all! What a way to start the 2013 season.

Season Opener Winners

Dante Paulazzo wins ITA on Saturday July 28 at Thunderhill.! Great Job Dante!

Thank you for another Haag Performance win.


Mike does great work, delivers on time, and charges fairly for his work. He has decades of experience working on Mazda cars, and when my race car needed a new engine, Mike was the logical choice. Mike built the engine from a donated core, and dyno-tuned the car for best performance. With the new motor, the car sounds great and runs even better, I can definitely tell the difference in pickup. I know where I will go for the next Miata racing engine

Haag Performance has a new Service to be able to provide to our customers.  Fuel injection checking, cleaning and flowing service. Please call Mike for an appointment.  If you say you saw it on our website, you will get a $10.00 discount.

Mike Haag and his family at Haag Performance are top notch. Besides being an excellent engine builder, he provides exceptional service. I came to him off a referral from another friend of mine and I was not disappointed. My engine died in my 91 Miata, a track car, and Mike and his staff helped get another engine in the car and back on the road in no time. He was fast and fair with pricing of the labor to get my engine replaced and other miscellaneous parts replacement (clutch/engine mounts/seals/timing belt/water pump/fluids). I experienced a small issue after the repair and Mike rectified that issue very quickly. Highly recommended business if you are looking to get a very knowledgeable Miata engine rebuilder. Oh, and my car runs much faster than it ever did.

We have moved our shop two shops down from were we were. We are not completly done yet but are still doing business as usual. With our new shop we will be able to function and take care of our customers a lot better.  We have much more room to work with. We are excited with what new experiences our shop will bring. Come by and see us and or give a call.
