Originally posted by Sweed95vert I'm on my third stang and have had 3.73s installed on each. The first was an 88GT 5-speed, Second a 94GT Auto, and the third a 95 5-speed. Since you have a pre 1994 car, you can't go wrong with 3.73s. There is still plenty off RPM at highway speed...unless you like to run 80 mph + all the time.
The 94 & 95 cars have a higher (numerically) first gear ratio in the trans that makes first gear really short with 3.73 and a five speed. But the look on your buddy's face when you slam the gas is worth the quick shift.
I have seen quite a few e-mails from people who purchased 3.55s and then wished they'd gone with 3.73. I have yet to read e-mail from someone with 3.73s that says, wished I gone with 3.55s.
Do the right thing.
The 5spd in the 94- 95 have the SAME 3.35 1st gear ratio as the fox body 5.0 T-5.
Originally posted by jeff90lx I just installed 3.73 and a spool into my 90lx, if I had to go make the chioce again I would go 3.55's. I just finished the install earlier today and sure as **** if I didn't see a brand new 2003 gt that wanted a piece of my 5.0. We rolled out from about 45mph, I was on it hard and pulled him by about 3 car links but I ran out of tach in fifth at about 115mph or maybe even 110mph. So if you like that top speed or drive on the highway much I would stick with the 3.55's,
You ran out of top speed? Not possible buddy. You can install 4.88's and still have a top speed of 140mph.

hmmm, I have 4.56's in my daily driven 91notchback which sees quite it's share of highway miles. I get 22mpg when I drive normal, well normal for me, and I have seen as good as 25mpg on the highway when I'm driving with someone who is speed limit conscious. I don't know if it's just me, but my stock motor has never had a problem pulling in fifth gear, of course that's due to the gearing, saying that a car with gears can't pull in fifth is like saying a stang with stock gears can't pull in fourth it's absolutely ridiculous, I race motorcycles on the highway, I have raced a saleen s281e on the highway, and I have never had a problem pulling to 5500 rpm's in fifth, once on a long interstate stretch I hit 6000 rpms in fifth. Of course, a fast car could have the potential to beat me if I hit my top speed and he still had more, but, like in the case of many many cars they don't pull nearly as hard as my stang so i'm long gone while they are still trying to catch up. I don't know what the big stigma is about gears and running too much rpm, 3.73 are a mild gear and I think stock mustangs should have at least come with them, and as for top speed? The mustang convertible massguy mentioned in an earlier post was fully capable of hitting 140mph, I can attest to this as the previous owner had a $1200 speeding ticket to prove it, and that engine was tired, it only pushed about 15-20psi of oil pressure b/c the previous owner let the oil go for more then 18000 miles before he changed it b/c he just wanted it to die!

Have you ever driven a 4 cylinder mustang? I have owned plenty, and even my brand new 93 with it's silly dual spark plugs took like 15 minutes to hit 120, come on that's like saying that a chevette can beat a stang with gears.4.10 are not some crazy extreme gear, I think that when modding a mustang that does not have the aid of a supercharger or some other good power adder gears should be the first thing done, and 4.10's are the way to go hands down.

Well, a stock 5.0 motor makes no power after 5000 until you at least do exhaust and stuff, still not worth going past 5200 (from track experience). At 5900 you are going ot have some serious valve float with a stock Mustang, I would never even try to rev mine that high. Only time it has seen close to that is in 1st from it spinning so bad maybe and revving up real fast. At speeds over 100, it is harder to accelerate and you are not going to pull "good" past 5000 in STOCK mustang. I've had a alot of 5.0's, some auto some 5spd and thats the way it is. My 93 GT is plenty strong too running a 13.80@100 on a dead stock motor with just exhaust and pulleys. I maxed out at 4200 in 5th gear with 3.27's before the SC. 4.56 is alot of gear, can't see it getting over 20mph though..that would be like my driving around in 4th. I prefer not to break my engine though. I only rev to a max of 5400 even with the SC..but the car is fast...
Originally posted by Johns90GT I installed 3:55s yesterday and I am very happy with them. I get a little less traction but a ton better pickup and since I drive on the highway, the RPMS aren't really way up there. I'm very pleased with having 3:55s in my daily driver. If you don't drive your mustang on the highway or don't drive it very often I would go with 3:73s those aren't much different from 3:55s but I chose 3:55s simply because I drive my stang daily and I want traction and better acceleration without spending money on wider tires and bigger rims, it all equals out 3:55 and 3:73s I'm pretty sure theres not much of a difference when you go to the track to compare the two in the exact same car.
Exactly. I bought a complete rear end with 3.55's in it already. All I can say is wow. So far, gears have given me the biggest increase in performance than all the other mods i have done put together (Cobra manifold, offroad pipe, ignition, MAF, and throttle body).

whats the 1st and second gear ratio on the 4 cyl 5 spd trans? yes i know they are weak but i can get them for $60 canadian a pop at the salvage yard and have a 3 month warrenty. i think like 3.27's with a 4cyl trans would be a good combo i drive alot of highway like 100 miles a day i have 2.73's right now im gonna play around with gearing once the snow melts.
wow ive read this whole thread and im soo confused my stonach feels sicks! i herd that 4 cyl trans make the best of both worlds im going with that and i think i could get better mileage with like3.27 and a 4cyl tans cause the 3 4 5th gears are the same and 1st and 2nd will feel like 3.55's or 3.73 what else could u ask for!? thats perfect i dont care if i blow them up if i shift with my clutch i'll be ok and $60 canadian with a 3 month warreny i can go wrong. summer only lasts like 5 months up here anyway! soo haha im laughing
I tjhink I need the 3.73 for my ragtop with only bolt ons because I am a little heavy. If I dont like it I could get bigger tires or even put in a six speed to compensate on the freeway! Anyways that is my .02C worth!
Woohooo!!! and Yeeeehawwww!!! I finally got my 3.73 gears. I'm having them put in on Sat. (Valentines day) Afterwards I'm taking my girl out for a nice dinner. It's gonna be hard to resist going WOT but I'll be good till it's broken in, I promise.
My 3.73 has been installed. It's raining today so I can't get a true feel for them yet. It definitely moves better than the 3.08 that was in there.
People have said it feels like the car lost weight and others say it feels like the car gained 50hp. I don't think it feels like either really. I just notice that I'm in the powerband quicker and have to shift a bit sooner.
All in all it's awesome and I'd recommend it to anyone. I can't wait till the roads are dry and they are broken in so I can punch it to see how much traction I lost
Hey guys i was just wondering if any of yall knew what type of gear comes stock in a 1992 LX 5.0. I've hear that they are 3:24 and i've heard that they are 2:37. I'm thinking about putting some gear in my car and i need to know for sure what kinda gear it has in it.
