Yep, well said. I did an autox in a small lot with a BMW club once where I never left 1st gear. The car was too jittery and jumpy to have fun navigating around cones at a max of 30-35 mph. It's just the wrong tool for the job.

the last time i saw someone do an autox in 1st they blew the motor.

apparently s2000 drivers never heard of momentum.

You mean the gas pedal isn't an on/off switch?

My motor has about 20 more hours on it at WOT since that bimmer event, so I guess I did OK.

Yes, you are right. And thats why I don't really care about what class I'm put in either but I don't know, i definitely didn't want to be slower or loose the usefulness of first gear. If the second gear spool does not work out on my track, second will be a boring gear. Luckily, even if I don't get traction in first, it will be

But maybe 2nd will work out

I bet 2nd will be a lot of fun on the street or at the track with a GT2554.

I have a t25 though. :/

Man, turbo with second gear might actually be faster AND perhaps less wear and tear because I won't be revving it up to 7k. Might just be perfect

GT is the BB version, but they're the same size turbo.

Not really on a turbo this size. Yes it'll spool a little quicker but a 2554 journal bearing is going to spool lightning quick on a VVT 1.8. You seriously have nothing to worry about.
