This just in!!
Dear Class 1000 participant,
There has been a lot of discussion in regards to the motors that are currently available in your class. As most of you are aware, the 2.4 DI engine is no longer available from GM as a new crate engine. 2014 was the last year that a production vehicle used the 2.4 DI engine. By federal law, they must supply parts for that vehicle for 7 years after last production date of that specific make and model. The engine is now only available as a re manufactured version.
Through our friends at General Motors, we were able to talk to the lead engineer who oversees the production of the 2.4 DI engine. After talking with this engineer, here is what we have learned they are doing to the re manufactured engine.

- Cylinders- Bore ¼ millimeter over stock- if needed
- Cranks- Reground ¼ millimeter under factory spec- if needed
- Cams- Measure and polish if needed- no grinding of cams. If the cams are out of factory spec tolerances, they are replaced with brand new cams.
- Valve Guides Replace with oversized valve guides/ epoxy in place- if needed
- Valves Replace with Factory stock valve
- Heads No decking of heads below factory spec. If heads are out of factory spec tolerances, they are replaced with brand new heads.
