How much power can a standard Supra 5 speed take? approximately.
I have read a few different things and have also been told different things. I have been told things btw 200 to 300HP but I have also heard about people using stock supra 5 speeds behind V8's that generate more than 350HP.
I just read some stuff from another site, the link is in the other thread:
http://www.gmh-toran...t=0
which is:
http://users.tpg.com.../gearboxes.html
Which talk about HP figures which are a lot lower still.
So now I'm a little confused about the practicality of using one of these behind a 308, (mild or worked). Especially when dumping the clutch may become a daily exercise.

well i wasn't aware they were measured by HP i thought they were measure by how much torque they could handle ....
either way i thought figures were something like 300Nm for the celica an 350Nm for the supra, or 250 and 300 ... can't remember.
also, i can tell you from experience, dumbing the clutch is going to kill stuff no matter what box you have i reckon .... i have a celica behind a 202 and i blew a box up from burnouts etc ....

This website has some good info about all supra boxes with a few HP figures quoted.

I had a w57 supra box in my Torana with a E38 and E49 spec and another performance grind cam hemi 265 in front of it and had no problems with it for 10 years.
228 rwhp on the Ford Muscle Parts dyno and 430nm....I am told the FMP dyno reads lower than others and my 265 injected hemi put out more hp+nm than GT spec 351's.
I did some burnouts and 2nd and 3rd gear drifts out of some corners...
The box is now in a Turbo 13b RX 7 and the owner is very happy with it.
The w57 is so much stronger than a M21 or T5 but lacks the pose value for bar room bs.

The commodore cup racers have been using the w series supra box for over 5 years and they dont have any problems with the gearbox.
It is the ONLY gearbox they are allowed to use and they run a pretty warm 253V8 for the engine.
They used VB-VH commodores and now run the VS.
If anyone has a CAMS rulebook they can look it up.

I think you will find that the Comm. Cup cars have used a Super T10 gearbox for quite a few years now because the Supre boxes weren't reliable enough.
However if you've ever watched a C C race and seen how close it is, you can imagine the torture the boxes have to withstand. A bit different to driving on the street.

Check out www.commodorecup.com and click on regulations, choose either the VC/H or VR/S regs and open them. Scroll down to page 10 from memory and read which gearbox they have to use.
I don't want to argue , I just want to make sure nobody else reads something that isn't correct.
I also don't want to bag the Supra 5 speed, they are an ace gearbox to use, really nice ratios and fairly strong. I've got one myself behind a 308 in a VC Commodore. However in full racing conditions, they do have their weaknesses.
I wouldn't hesitate to recomend it to anyone behind a mild 308, and I'm interested to hear from anybody running them behind big HP engines.

1. Torque from a engine is what breaks gear teeth.
2. I wouldnt even trust a celica box behind a 173.
3. standard 308 pumps around 427 Nm
4. Tremec!
5. Auto will do for now, funds are tight at the moment.

mate there are two types of supra boxes...
there is the w57 which is goor for about 300hp
and then there is the r154 box alot better and if its out of the right car itll be able to handle about 500 hp...
all depending upon torque... but yer a good r154 will set u back around 1500...

I use a w57 in my 500rwhp turbo trana. I use 3.55 in the rears to take a bit of load from the box. It will cope with 3-400 rwhp well but over 400 3rd gear will let go after a while.
I tend to load it up in 1st 2nd and 4th but not in 3rd and dont even think about loading it up in 5th. 3rd is where you get heaps of torque and 4th is direct drive which will probably take 1000hp

Hope it's not a stupid question ...
I'm not sure if I've missed something here but whats the big difference between the supra and celica boxes? are the celica boxes just a hell of a lot weaker? are they as adaptable to the holden 6's as the supra boxes or what?
Cheers

i think you've got it LC2250 from wat i gather the only difference is the amount of power u can put behind it. and yes they are as adaptable as the supras (someone please correct me if i'm wrong on that one)

m22 atm. looks like i will be getting a supra 5 speed...
and to answer the " worse than my $80 m20?" question, probably about on par, perhaps a tiny bit stronger.
