Rotary engines and Rx7/Rx8 service
 

Engine rebuild service with engine removal and install. 

Defined Autoworks understands that many customers do not wish to remove the engine themselves. We offer complete professional service and rebuild from A to B.  There is much more time involved and variables to a complete car brought in, but here is the base pricing across the popular generations. Pricing includes new coolant, oil, oil filter, spark plugs and supplies. A startup and test run of 40 miles is performed to ensure the job is completed properly. Cars that have been sitting for multiple years will be a substantially higher cost than the baseline.
