A good choice if you are going motor and want something good is to get the Si tranny like what's in my car. 4.4 FD makes it really nice to keep it n the power band and much cheaper than an ITR. Then you can get a CTR/ITR diff for around 290-350 shipped from the guy i got mine and you'll have the ITR tranny with what IMO is an optimal gear for the Honda. The ITR 4.79 FD is a little steep. I am already around 4000 rpm at 70mph with my car. If you were just road racing/autox it would be better to have the shorter gear but for a drag racer/dd the 4.4 will be really good. You should be able to cross the 1320 maxing out 4th once you do some mods and with the right height tire on it.
