gearing change is only for those that run for fun or are otherwise not competing in classification based on vehicle spec, i.e. STX, etc.

if you change your gearing for autocross purposes, they'd classify you with one of the unlimited cars and then you're stuck running against cars with full slicks and aero. then the bigger question is, why autocross?

part of the "redline too long" on autocross courses is the course itself, it's temporary and often changes based on the venue. depending on who is designing it and the length between corners, for some cars it's an unfortunate reality that you'll be stuck at redline on some gears. it's sort of a tactical decision but each driver will approach the course differently... but this is uniquely an autocross problem. the same setup on a car can yield vastly different driving on the same venue if the course changes.

for open track days, gearing change is fine.

I just got back from an invite only Toyota Canada Track day, using my car the way they intended, and test driving the new Supra.

We are getting off topic but what do you think the solution is? I've seen engines that the casual enthusiast considers bulletproof F20c, K20A have oil issues issues as well in the upper revs.

mav1178: i wonder if higher redline can be made a bit less dangerous if ecu tune gets modified to not get max power if past stock redline, but to gradually reduce it .. yes, at high rpms oiling gets inadequate, but if you require from 8K rpms only eg. 30% of max power, that should reduce a bit wear/risks, and still be more effective then bouncing off limiter at 7.4K?

Toyota figured out how to rev it higher 5 years ago. Maybe only for a few laps though lol
