Engine builder recommendation

[Rmag911]

My engine died in the middle of a race this weekend (oil line broke). After repairing the oil hose, the engine is still low on compression so it looks like I need a rebuild. Who are the good Pro Mazda engine builders? Any info is greatly appreciated. Thanks,

I just had a Formula Mazda engine rebuilt by Rotary Ressurection in Knoxville/Morristown, Tennessee and, so far, it's running great. My irons were not salvageable and I didn't need a sealed engine, so they were able to scrounge together some newer components and the existing components that were specific to the car to make it all work. I think I picked up almost 20 horsepower in the process. The entire process (from teardown to final assembly) was fully documented with measurements and photographs. After I reinstalled it, it fired right up and ran great. For me, however, it was only about three hours away and I happened to be driving through Knoxville when it was ready, so they were really convenient. When my Pro Formula Mazda engine needs a rebuild, I won't hesitate to send it to them.
