Thanks for the advice. I've actually already bought the pulley/tune before i even thought about autocross.

I don't really plan on doing it very competitively so I won't be dumping a bunch of money specifically for it. However I have thought about getting the sprintbooster. Would this give me a noticeable difference?

Honestly I wish I had a car with less power to work with in this sport so I could get the skills down first. Unfortunately my MR2 is going to the junkyard, and I'd have to put about 2k in suspension and brakes on my maxima just to make it safe.
