Ti·Speed Engineering Engines are built using ALL NEW internal components.  Few builders can make this claim.  Spec Miata Engines are pushed beyond their designed limits time and time again.  Warranty or no warranty, a blown motor at the track ends your race weekend.  We strive to produce the highest quality products with the most power available. 

All Ti·Speed engines are personally built by former Ford Motor Company and NASCAR Sprint Cup engineer, Dan Tiley, with 15 years in the industry.  Every engine we build receives the same careful attention to detail, and is based on the results from countless hours of dyno, flowbench, and racing experience
