T5? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Does anyone know if the BA XR6 (non turbo) has the T5 manual gearbox like the Turbo? I originally thought so, but I read that the first gear in the Turbo is about 2.95 versus the 3.5 in my non Turbo. If it isnt, how much power (torque) can it handle?

First gear in the BA non Turbo models is either 3.35 or 3.05, I don't recall which. The 3.5 ratio box is the old EA box. The Torque rating is SIGNIFICANTLY lower in this box compared to the T.

Sorry, I meant 3.35 not 3.5.

So its just a weaker version of the T5 with a lower first gear?

Your box is a T5. The XR6T box is a T5Z.

Basically, yes.

Weeell, not really. Each box changed slightly. EA was T-50D, if memory serves. Then EB/ED was T-50E, different ratios. Also the later T-50E was modified to accept a race bearing on the manishaft/input shaft, rather than the old needle bearings, which chewed out the mainshaft.
Then the EF/EL was a T-50something else

, and the AU was different again.

T5 is apparently good for 300rwkw, I vaguely remember seeing somebody on here a while ago saying they were getting 300 rwkw out of their blown 4L with a stock manual in it, EB I think.

You are talking about minor upgrades to improve noise and reliability. When you talk about torque carrying capacity, there are 4 major jumps. EA has a 22 tooth input shaft. EB-EL(AU) XR6 has a 23 tooth input shaft and is stronger. EB-EL V8 has a 24 tooth input shaft and and is stronger still. AU XR8 and BA XR6T have a 24 tooth input shaft and a vastly better grade of heat treatment used in the gears (Z spec)(They are made by Tremec). They are the strongest T5 available, having a 10% better torque rating than the old V8 box.
I have recently done 2 Turbos with 330RWKW that both had wrecked T5's, both at zero km at this power level, (wrecked before getting off dyno), and I did one yesterday that has only done 25k, only 2k of which with a Phase II kit (270RWKW), and the T5 in it was wrecked as well. Note all three of these were not flogged, there was no dog damage, only severe undercut wear on the contact patch on the the input shaft, cluster and third gear. Ben.

I stand corrected

Hadn't heard about the input shafts. Well, that's my new thing learned for today, and it's only 3:40 in the morning! :)

I had the stock au t5 in my v8 ute. I installed a vortec and killed the box soon after. 220 odd rwkw and a bag full of TQ. I have changed to 3 spd c10 auto (firm shifts), but had to dump the s/c when i moved to make some quick cash. I would love to know what sort of power the old/new auto's pull out of these things on the dyno compared to manuals. i make 137 rwkw last dyno N/A with auto, how would that compare to manual with similar mods to mine. thanks guys and sorry for lil hijack.
