Adventures in PTE/TTE

Oops, I have a set of '03 calipers and brackets and a master, booster and prop valve sitting in the garage ready to put on my TTE '99; AND I don't have 3 points to spare.
Less than 5 weeks until our first TX event, in the past how early have the rules been finalized for the next year?

if you are running a points car...do you normally take the point for the PS pump and run a depowered rack, or are most people keeping the power steering? Definitely seems like a lot less fun to run the PS, but that point could probably be better spent else where...

it would seem you are correct sir:

newbie mistake on my part!

I can not find any mention of power steering or the steering rack in the points section except for shimming the rack to fix bump steer.
Looks like adding power steering is free, at least as of 2011 it was:

Is there a clear winner on the "to dyno reclass or not" question for PTE with a NB2? Looks like you want to get to 145whp with a NB2 if you class on points. Getting there I'd imagine would take an ECU (+3), Intake (+1), Header (+2) and Exhaust (+2) which is about 8 points. If you dyno reclass you'll take a hit in your p:w but you basically get 8 extra points (possibly less if you spend more on tuning/0-point motor work) and a considerably "better" torque curve. So you could run a lot more tire, or throw some aero on.
I'm leaning towards dyno reclass, not entirely for performance reasons. It would be nice to be able to uncork the motor when I'm at a DE for some extra umf as well as things like power-steering delete and harmonic damper replacement.

"Most of the decisions have been made. A6's are now 50 points, Miatas all start in TTC, etc."

Damn. I was thinking about this some more. Let's say that the base weight goes up for points cars, and as mentioned the dyno reclasses become less favorable. The dyno reclassed cars will clearly be slower than before. However, the points based cars (being limited by the class maximum power to weight ratio), will be able to tune in more power to offset the added base weight.
This makes going the points classed route a bit more appealing. Too bad I've already committed myself to sticking with the dyno reclass route...

Since I'm swapping a VVT into a 1.6 car, I have no option but to dyno reclass. I can't imagine being able to build a points 1.6 motor that could compete, even with the substantially lower weight.
