Hey guys whats up, I have a b18c1 in my car and a friend of mine told me that he would get me a 99 si tranny for me for free. All he wants in return is my gsr tranny. Now I know that the si tranny would be better then the gsr tranny if I was going all-motor. But I was planning on going turbo. So my question is should I trade him trannys and be faster right now while I am all motor, or should I keep the gsr tranny for when I put the turbo on? Another question, about how much quicker if any would my car be with the gsr tranny then the si tranny when I put the turbo on?? thanks in advance!
