I started crewing on RX7s in the WDC region when I was 13 - my dad's friends decided to go racing, and I started helping out at driver's school. at the time, I basically recorded times, tire pressures and temps, and gathered the stray air dam from the tower after it was recovered from the side fo the track.
byt the time I was 19, I would drive my van tot he track, sleep accross the road from registration, and use the mornign traffic as an alarm. if I didn't have work arranged ahead of time, I knoew wnough people that I could sign on with and just help out where I could that weekend, guys who showed up alone like you.
I moved south, met my current gang, and have been wrenching on their cars since. Dave sent me to driver's school in his BRAND NEW FP civic that I helped to build, and it was the scariest thing I've ever done (in WAY over my head)- but it gave me a serious appreciation for the car that I hadn't had at the time. I'm still in porcess on my car, and raced a bit in the IT civic since then.
point is - some of us really like to crew. there's somethign about the overnight thrash replacing motors at the track, or between weekends. we meet up a few days a week and work on the cars and hang out (well did, I had a baby). I'm sure you will find a good group with a simillar car as suggested, and you might want to consider heading out NOW to afew events and meeting them before you make it to the track as a driver. help them out, learn from them, and you;'ll likely find them helping you at your school and beyond.
aside from that, find some gearhead kid who's dad is your friend, and drag him along, he'll love it.
