Thanks, Tom.
For the spreadsheet, I will use the used-engine strategy. I believe that's what most of the guys in norcal are doing also. Most here have been using the same factory engine for several years, and no one really knows when they will stop producing competitive power. They seem to last forever.
In which case, I will use $2,500 and 100 hours. That should about four years of racing for most guys. About $78 per weekend. Pretty good. One of the lowest on my spreadsheet. Brake pads are a little pricey and the gearbox is a weak point, but overall, SPB is a lot cheaper to run then Spec Miata.
Thanks for your help.
