My son is racing a 03 lancer oz rally on a 1/4 mile asphalt oval I am trying to find a tranny swap to get a.higher 2nd gear or a lower 3rd gear. Right now he can run good times in 2nd but it hitting the rev limiter and has blowen one motor, in 3rd he is a full second slower becuse he cant get up to speed comming out of the corner. Is there a direct swap out there that would give me a better gear option?
