You seem to know quite a bit about these cars! Unfortunately (depending on how you look at it) mine does have the ALB option and power locks & windows as well as fog lights. I see now from Ron's comment that I can run in FSP with the different engine because the 88-89 Si had the 2.0, while the 90-91 Si had the 2.1.
It sounds like you're saying basically if I were to delete the ALB with all the parts from a non ALB car, and leave everything else alone, I can run in STC?
The only reason this is a big deal is because SMF will kill me on index, and FSP no one runs in my region, and running unopposed is no fun, so I really want to get the car in STC if I can. Looks like as the car sits now though that isn't possible. It's either put a B21 back in it, or delete the ABS maybe. I've tried to find an exact list of standard equipment from Honda for the 2.0Si and the Si, but all I can find is what people on other forums claim is standard on each model.
