Changed 5th gear ratio-tremec T3650

For those of you that have this box you will know it is a huge distance between 4th and 5th gear and the car dies in the ar*e and on hills gives no performance. I drove 900km to Mal Woods and had him change the ratio of 5th gear and what a difference it made, this car on the Putty road now convincingly overtakes up hill in 5th. I went from 0.62 to
0.74 and it now revs just under 2250 at 100km/h and around 2400 at 120km/h. I never drove (mostly) faster than this anyway but now it gets up and goes when you put your foot down at that speed in 5th. Overdrive can also be used from 70km/h now. It was a good low cost mod.($700)
more than happy but a six speeder would be better. At $7000 I will have to think about that one.

I think Shaynet has done this as well. I have no prob with 5th gear in my ute. It will still pull up a decent hill in 5th as well.

I do agree a 6sp would be nice tho...

Dont get me wrong it still pulled on hills with the torque but the accelleration was more datsun 180B-ish. now it goes like a 5.6 should in fifth. Just a personal preference of course but i am more than happy at the moment. Cheers.
