I'm not a grouch but you'll get that from my future responses no doubt. We run almost strictly canadian events because that's where we live lol. We've run Black River once but it's a NASA event anyways.
In Canada they just changed the class structure for 2013 to make things really simple:
Being that we used to be in an NA under 2.3L adjusted displacement (1.15 mutiplier for dohc) 2wd class (it was called group 2) and have now been combined with 32mm inlet restrictor turbo 2wd cars, we're going to stay NA. I'm doing some headwork this season and a full built race engine in a year or two with around 220whp+. This year I'm expecting to end up with around 160-170whp.
An awd conversion is a little excessive. I'm not sure what driveline to source and Subarus and Evos already come with a great one if you get my drift. Not to mention that a properly driven 2wd car can take open cars.
