If patience is a virtue, then building a Renesis the way we have is one of the more virtuous pursuits we’ve undertaken. Not that it takes all that long to assemble a rotary engine—engine builder Joe Ferguson assembled ours in a couple of hours—but getting all the parts ordered and prepped for assembly does take some time. Here’s how the entire process went for us, from beginning to end.
So far we’ve put 200 miles on the engine following Mazdaspeed Motorsports’ recommended break-in procedure (information we gained access to by signing up with Mazdaspeed’s racer program, which also entitled us to parts discounts and a very generous contingency program). Although we had to troubleshoot an engine code (a phantom misfire from a bad knock sensor), so far all signs point to zoom zoom. Next month, MazdaManiac will be handling dyno tuning using a Cobb AccessPort. We can’t wait to hear this engine rev to 10,500 rpm.
