P2 and FB
1. #25047 (Club Racing Board ) Stock Engines
Competitors in P2 and FB are reminded that a stock engine consists of parts that were originally delivered as an OEM unit. A stock engine is NOT an engine made up of stock parts from various engines and different platforms to create an engine that never existed as an OEM unit.
All the engine part numbers must have been included in, or superseded in the original OEM engine. For example, an engine with a short block from one engine platform, cylinder head from a different platform and cams from a third is not a stock engine
Sadly, this stock engine definition applies to P2 also. When this advisory was first mentioned, letters were written to the CRB but to no avail. A few years ago, I dropped a valve in my 05/06 GSXR which trashed the head, pistons, and the cylinder wall. The result was an 05\06 EBAY head and cylinder block plus the pistons/rods/bearings/valves. Crank and full bottom were reusable. Engine performance was not changed. Currently, the 07/08 GSXRs are in short supply so the value of rebuilding one becomes significantly higher at a time when SCCA is trying to keep P2 an affordable class. One could rebuild a stock GSXR using parts that are all found in the OEM parts list keeping the stock engine performance but be found guilty under this advisory. We are all going to have to keep these 08 GSXRs alive. Going to a Busa is a $12-15K expenditure for me even doing the work myself.
Maybe even more sadly, a stock 1000 engine in P2 has become non-competitive as compared to the built 1000, Busa, etc. Thus I really cannot see the necessity or rationale behind banning rebuilt engines.
While the authors might have thought they were exact in their wording and got their meaning across, I think the discussions in this thread and others have shown that various interpretations are possible. Having lived in a professional world where precise wording and punctuation was necessary to remove all options for possible miscommunication, I understand the complexities that arise.
