I agree 100%. No limit on Motor size. It's 5 unlimited leave the motors unlimited. Im not sure when BITD changed their motor rules for class 5 but last year it was ANY size four cylinder air or water cooled ANY make. Did not have to be VW. I thought that rule would bring some cars to the class but apparently it didn't.
I like the idea of any four cylinder unlimited mods!
If it has four cylinders bring it!
It seemed like BITD had that change of rules only for 2011. During 2011 we bought our Ecotec thinking it was legal. Some say a miss print, who knows. We made many phone calls and typed lots of emails back and forth to BITD asking if the any 4 cyl. Motor would b ok, and they said yes. That's obviously not the case anymore. We have now designed our car around the Eco.
