      Seems like a relatively small step to go new.



      Plus you'd have the choice of close or wide ratio gearing. Take a little time with this to determine which will best fit your use. Keep in mind that you'll want to have at least 65 mph available in 2nd gear for autocross (having to shift back and forth between 2nd and 3rd kind of sucks when you're that busy). You'll also have to consider axle gearing here, but if that isn't quite right pick the transmission first and choose axle gears to dial it in to your driving needs. If you do the speeds in gears math with the online calculators, either reduce those speeds at rpm by 3% or increase the revs at those speeds by 3%. It might be enough to make a difference in your choice. Let me know if I can help here.
