What the diffrence between the Ford t5 box and the Holden(s**t) t5 box? Also see nissan and saabs have them too, Are they completly diffrent or is there some similirity or does it come down to spline counts etc? Cheers

Saab's are front wheel drive with the front of the engine facing the firewall.....how can it have a T5?????..........as for Nissan, they have their own box...of some Jap brand.

i thnk the boxes are basically the same...

different bellhousing obviously
different input shaft (length & spline???)
output shaft length????
shifter posn???
ratios may be slightly diff??

Yeah dont know where i got saab from, mean sbc, i got the s right lol. So all the nissan ones and holden ones are no go into falcons, there all called t5's but theres diffrent types of t5's not just the bellhousings?

Yep, different kinds. Even the Ford Windsor V8 T5 has different ratios and a longer input shaft length, compared to the 4L T5.

Weird, why didnt they name them diffrently so people like me dont get confused lol, cheers for the info guys

Because they are still the same box?

Difference between commodore boxes and falcon boxes are input shaft lengths, which are also different from those of a ford v8, and also different between the commodore v6 and v8. Uncertain on commodore ratios, however if you have a t5 housing you can swap any world class T5 gear set with another, but you have to use the whole set or else it won't work and if it does you will find your ratios all f**k up.

In other words, if for some reason you had a commodore t5 housing and you put an i6 ford t5 gear set in it, it would bolt up to the ford i6 bellhousing and straight onto a ford i6. Note there is absolutely no advantage in this, only advantages in ratio changes can be had if you are using behind a v8.
