Hey guys, so ive been kind of trolling around on here for a little while now. I finally picked up a fox body mustang this summer. Ive wanted one since I was 16, and finally have one. I have a 92 gt cobra, with a built 351 windsor 5.8L motor. Its street tuned with Quarterhorse and I was told its around 350 whp. One thing im worried about though is the car was originally and automatic but it was converted to a standard. It still has the automatic rear end. I was told I should get it changed. This si just a toy for me and I would love to be able to bring it to the track with the slicks I have for it, but I would like to be able to drive it home after lol. I was told the drive shaft is only a few years old and is in good shape. I really dont have any knowledge in mustangs as I was a honda guy before lol Should I change out the rear end before bringing it to the track or what? I am very lost when it comes to mustangs lol I would love to supercharge this car is I keep it, but want to get it solid and strong before dont anymore to the motor... what are a few things I should look at first?

Thanks in advance
Mustang Noob

 

Change the rear end? No. the gears maybe.

By the way.... Go back to hard parking your honda at M&M.

 

Ahh gearing ok, see totally lost when it comes to this lol and no more hondas for me.. This is way more fun!

 

fwiw, the optional gearing for an automatic was 3.27 while the optional gearing for a stick was 3.08

Neither gears are great for performance though so it is a moot point. You want at least 3.55 but more likely 3.73's. 4.11's start getting the rev's up quite a bit even with the overdrive. It becomes more a question of what kind of compromise you want to make, street vs quarter mile?

Welcome to CMOC. There are a lot of knowledgeable guys here. I just pretend to be one

 

If you decide to buy new gears I can get you a good price at Campbells. I have a complete 8.8 rear end with a 3.73 in it but not sure it would fit your car from mine.

 

Thanks guys I will keep that in mind! If I keep this car, Its going to be a toy and not a daily driver so it won't play a huge part in which gears I go with.. I mean I would like to be a smooth and comfortable so when I do drive it in the summer its not a harsh drive

 

Nice comprimise would be the 3:73's and good luck

 

Welcome aboard!!
Oh,keep the diff,and swap the gears. It's the same diff for either auto or stick.

 

Congrats on the new ride. Like most said 3.73's would be great. 4.10's would be even more fun if you aren't driving long distances.

 

Welcome to the site dude, and 'grats on the new Mustang. Lot of guys to help out around here, some of the info you can even use! lol
