As you may or may not know I am putting together a budget turbo project . I have a T3/T04E-57mm turbo(thanx 240)and it will go on a junkyard turbo motor with stock ECCS . I am just in the midst of doing the head on the motor .Anyway I have a 3.7 LSD rear end and a 78 tranny . I was thinking about upgarding to to an 82 close ratio with larger overdrive . My way of thinking is that first and second won't be as steep and will allow the big turbo to spool up more . The closer ratios will not allow boost to fall off as much when shifting .
