but with that aside... as Mr. Kidd said... just try to find a shorter geared tranny such as Ys1 or S1 and get a factory lsd and you would probably be satisfied with the acceleration of that... but if you are planning on 9k, I'd recommend an aftermarket main cap girdle, lighter rotating assembly (balanced), High Pressure/Volume oil pump, ACL Race Bearings, a vtec head and some stiffer valve springs... I wouldn't recommend an Ls head hitting 9k (I've seen too much **** happen)
