Rotary Enthusiasts Speak
Hear from fellow rotary fans who trust us for quality components, knowledgeable support, and reliable worldwide delivery.
“These guys are absolute rotary wizards. I brought my RX-8 in for a rebuild, and they diagnosed the issue in minutes that my local shop spent days on. The team’s dedication to keeping rotaries alive is unmatched. If you own a rotary, this is the only place to go. They truly care about their work.”
— Jamie C., RX-8 Owner
“My FD has been a handful, but Bill Rotary Garage got it running smoother than ever. They are one of the few shops I trust with the unique challenges of a rotary engine . I live over a thousand miles away and still only bring my car here. Their knowledge and service are simply on another level.”
— Rob S., RX-7 FD Owner
I called with a tricky engine question and they took the time to walk me through it, no hesitation. You can tell they truly love these cars and know them inside and out. The passion and expertise here are genuine. I wouldn’t trust my rotary project to anyone else.
— Mark D., RX-7 Project Builder
