Are all T5 boxes the same??
Discussion
Guys
I have been researching gearboxes for my Griff, in particular what I might need for a 375 bhp motor. The concensous seems to be that i could be getting close to the margins for a standard T5 but obviously a lot will depend on driving style.
I will probably refesh the input shaft bearing but take my chances with my box and if it lets go look at the CTS Quaife option.
The question is are all T5s (Griff/Cerb/Tuscan/T350) all the same or are they spec'd for differnt torques? Am I right in assuming the T5 standard in the 4.5 AJP is generally upto the job in standard form and is this any different to the T5 in my 96 Grif?
Thanks

All TVR T5 boxes are more or less the same.
If you want to stay with a T5 type then you need to look at a Tremec TKO500/600 which as the numbers suggest are beefier (and heavier as a result) versions that will take the corresponding lbs/ft torque.
Tremec bought the rights to the T5 from BW so it's the same design just beefier

It depends how you drive, I run over 400bhp and even more than that in torque through mine, and its fine. The generally accepted limit is around 450bhp, though you can break one with much less if you enjoy dumping the clutch and aren't very smooth in the gear changes. At 375 it should be fine!

i was under the understanding that there was two versions, the standard and world class or something along them lines. and that the cerb had the latter of the two
From my understanding all the TVR T5's were WC. They are different from a sierra cosworth one I had one on my garage floor. The TVR ones are American based, (mustang I think rings a bell). I was running 420bhp and 550lbft on R888's and didnt break it...they are strong boxes if respected two different gearings available here, 1 for Cosworth & 1 for TVR

I'm sure they used to do a 6 gear conversion, but that may have been on the the LT77 box..... can't remember as it was along time ago I was looking into it.

They did indeed offer a 6 speed T5.http://www.gearboxman.co.uk/infot5.html
