I just feel like it would suck because yeah I would be pulling through 1st 2nd 3rd 4th then pow it will feel like I hit sludge in the road if I had the LS 5th but I also know I don't wanna drive around town tached to almost 4k! My 4k is at 80mph right now...the reason I was asking what the b16 tranny in 4 gear at 7k rpm was in mph was because I know that right now I don't need to see 5th in the quarter and my top speed for my 4th gear at 7k is 106ish. I need to know if I will be seeing 5th with the b16 tranny in the quarter mile with a 7k shift point because if I do have to shift to 5th I will probably pull a slower quarter with the b16 tranny installed.

As for the tires...I just bought 205/50/15 Kumho Ecsta ASTs (all four) about a week ago so new tires are out of the question.

How much do you think a tranny with a b16 1st-2nd, GSR 3rd-4th, LS 5th would cost? I wish I could do b16 1st-3rd GSR 4th LS 5th but I think that this combination wouldn't be possible.
