Street Prepared ?

If I understand the rules correctly.

Throttle Bodies, intake runners, and cams are not legal in SP.

Is that correct?

As I read it, throttlebodies (larger, or multiple) ARE SP legal, intake runners - not sure what you mean here, but the intake manifold is free in SP, I think. Cam change is NOT legal.

seems to be a bit fuzzy.

Oh, I'll be there. Staying at the Country Inn, test and tune Sat and Autox Sun.

As I recall, the intake/fuel system is completely open in SP with the exception of adding forced induction or changing boost levels. I've seen fuel injection systems scrapped in favor of multiple carburators as an example.

Now I remember seeing this at a Divisional on a CSP CRX.

So What about brakes?

Brake mods are fairly limited. You have lots of leeway in changing/adding proportioning valves, which is nice. However, you can't change calipers or go to larger rotors (you can use aftermarket rotors of the same size as stock). You can remove dust shields. Of course, you can change pads.

Note - the one loophole, and it's a BIG one for some cars, is you have full update/backdate with other years/models listed on the same line in the SP rules. This is huge for some cars - for example, it allows Mustangs to install Cobra brakes. For your car, probably not a big help, unless Toyota added larger brakes to later MR2 turbos.
