  1. 4 cylinder T5 in 5.0 problems.

    Classic Tech
    I put a 4 cylinder T5 in my 1986 Mustang GT and it has all the light to light power in the world but I tried to take it on the highway for the first time and I was in 5th gear at 3500 rpms and I was barley going 55. What can I do to get longer gears to go on the highway but still keep my low end...
  2. Cruise RPM for different gear ratios - 6MT

    2011-2014 Mustang Talk
    Guys, In reviewing a stack of 2011 GT Premium window stickers, I am trying to calibrate the choice of differential gears to what I currently drive... At 70 mph, what are the 6th gear RPM for each of the options for the 6MT car? Standard 3.31? 3.55? 3.73? TIA! :bigthumbsup
  3. BAMA Tune for a Manual with Dual Exhaust?

    2005-2010 V6 Mustang Tech
    Just wondering if anybody out there has gotten a BAMA tune, 91 or 87 octane, for their 4.0 with just dual exhaust? and if so how much of an improvement in power/ throttle response did you see? I'm thinking about getting a tuner and maybe 3.73s..? Just want to be sure. Thanks :bounce2:
  4. Factory 9 inch question

    Classic Tech
    Sorry, I'm kinda a newb when it comes to this stuff. I've got a 72 Fastback 351c 2v FMX with the factory 2.75 geared 28 spline 9 inch in the back. I'm wanting to swap the 3rd member for one with a lower gear and a limited slip. However, if there is one for 31 spline axleshafts should I be...
  5. Daily driver gearing?? 3.25, 3.73, 4.1?

    V6 Talk

  6. 1966 mustang damaged crown gear

    Classic Tech
    i have a 66 mustang with a 8" rear axle and last weekend, my dad and i opened the pumpkin and we found that about five of the teeth have been chipped and i was wondering if it is ok to put it back together and use it or is that a really bad thing to do.
  7. What's the stock rear end gearing in a 96 GT 5 speed?

    4.6L Tech
    I've read that they came with 2.73's, but when I jack the car up and rotate the rear tires, I'm getting somewhere around 3.3 revolutions of the driveshaft per wheel rotation. Did the 96 5 speed come with 3.27's, or 3.3 somethings, or has a previous owner done a gear swap? I've searched for...
  8. Does the 96 GT have a limited slip differential?

    4.6L Tech
    So I'm going to replace my rear end gears, but I don't even know if I have a limited slip (posi) rear end on my 96 GT. It would seem silly to build a performance oriented car without such, but hell, they also put 2.73's or something ridiculous like that in there from the factory. It seems that...
