Testimonials

  • Holleran’s did amazing work on my Porsche! John rebuilt my 3.6 from the block up. The work was done quickly (as quickly as can be expected for quality work on a high performance engine) and the cost was more than fair. John also made sure the rest of the car was in order and made adjustments to the transmission linkage and other systems so the car was at peak performance when I got my precious 911 back.

    Anyone that owns a Porsche knows that nothing is “cheap” but paying a fair price and having 100% confidence in the work can be priceless. I’m now planning my next 911 project and I know exactly who is building the motor, Holleran’s Performance.

  • The work and attention to detail from John is stellar. The 964 drove well before (minus the bad 3rd gear synchro) but after the G50 rebuild with a few goodies and his "special touch" it shifts and drives like a new car (in a good way). Just took it out on its first spirited canyon drive early this AM and bleap me, it's so good! 6 stars! Thanks again, John!

    My first time to take my car to Holleran’s Perforance and I can say John addressed all of my concerns. He communicated with me extremely well! Only problem is he is so proficient with his craft that his openings to work on your car is full due to his meticulous care that he will show with your car. I have owned earlier 911 E in the the past and would advise you that John is at the top of Porsche specialists.

    John Holleran’s expertise and attention to detail are second to none. He has not only serviced and tuned up my beloved Cayman, but he also was able to return my beautiful 912 to the road last year. His is the only shop I trust with my gorgeous Porsches. John has a genuine gift and a passion for what he does, and it shows in everything he puts his hands on.

    John at Holleran's Performance is a Porsche guru. Extremely conscientious, detail oriented and out of the box. A pleasure to work with and very fair. You will enjoy working with him.
