Another noob question here.

Post by noslack2mack » Thu Sep 23, 2010 3:11 pm

Hey is the short shaft T5 I keep reading about the same ones that Ford used in the 80's through '93 Mustangs? I know the SN95 (94-95) T5 is different somehow. Is that the difference?
I'm sure there's no point in goofing around, so I'm going with a World Class T5 when I do this. I'm interested in what gearing everyone is using with it though. I know about the 2.95 option one....the other I think is like 3.35??? The standard one ....whatever it was. Thanks for the feedback!
Anybody ever try to shoehorn a Tremec into one of these XR's? Maybe a TKO? Those were a common upgrade for a Fox body Mustang and I think Saleen was using them for a while before everything went 6 spd. Doubt it would fit and the bell housing would probably be a real ba5tard to do, but who knows. Just a thought.

I know you're asking questions, but you're not really making sense - no idea what you're asking re: short shaft.

The most common used T-5 is the 3.97 box, since that's what was used behind the 2.3 from the factory.

All Ford T5s got the same length input shaft (although the V8s have a larger pilot), except for '94+ and newer. '94 and '95 was the only years for the long input T5 behind a V8, but the V6s continued to get the long input T5 for a number of years.

FWIW, the long input shaft is about .5" longer than the standard one:

DPDISXR4Ti - I think the breakdown of our communication may be in that I've been telling myself that I will be using a V8 T5???? My thinking was- A) I get more banging before the tranny goes *BANG because they are rated for more torque. B) A V8 T5 is easier for me to find since everyone I know has Mustang stuff laying around. C) If I wait and watch, I might find that slick Cobra job with the tapered bearing. But I see now that the gearing of the V8 stuff is not right. Soooo.... I'm stuck with a 2.3 T5??? Alllllllllllllrighty then. Aren't they like 200lb/ft or something????





MerkXRTurbo- Hey thanks for the info! That pic is exactly what I was thinking about.

The 2.3 T5s are rated for like 235 lb/ft or something like that, but I have put CONSIDERABLY more power through them and driven the piss out of them with no problems.

The gearing for the V8 T5s is fine. I wouldn't run a 3.36 rear with a 4 cylinder, but 3.64 rear should be fine. Nice tall OD for cruising! 8)

Not so fast there.
Look at the gearing the manual Xratty comes with and look at the common mid80s /early 90s V8 Ford T5s had---virtually indistinguishable,except 5th.
Indeed the differences could be simple math rounding off differences.

Look at the complaints people have of the stock type 9: 1st is too short.

Does it make sense to gear 1st another 15% shorter to 3.97???

You making a pick up truck???

The steps in the gearboxes are there depending on what the powerband looks like and a well done turbo 2300 will have a very FAT very broad powerband---if you don't fall for all the silly talk that bigger is always better.

So a common V8 box with a rear axle geared higher---to around 3.36 works nicely or better---gives you much more final drive options is the 2.95 gearset---it was Fords choice when they wanted a strong box in the 2wd Cossies, same 2.95 set except a shorter top. With the 2.95 gearset anything from 3.64 to 4,3 axle will work fine depending on what end use is...
