I`ve heard some good reports about the toyota gearbox - but make sure you go for the right one.
The one to go for is from a toyota Supra 3.0 litre turbo - it is known as the R154
The non turbo Supra has W - series box which is not up to the job.
The twin turbo Supra has the 6speed V161 (I think) and as far as I know, although stronger still, there are no bellhousings/adaptors available to make it fit.
Hotrodders "down under" use the R154 a lot due to the price difference between toyota`s (apparantly there`s plenty in the scrapyards there) compared to importing a tremec for example from the states. These guys give many good reports as the toyota box being "near indestructable".
I myself have a R154 sitting in the workshop which came along at the right price and a bell housing/clutch conversion is available from....

If you look at some of the Supra forums on the net, some of these guys are putting very high hp figures through the same gearbox. Although I realise it`s torque that destroys boxes - some of the Supra guys are putting a lot more torque through them than I ever would need to.

hi bill

i have been using a supra box for the last year no probs. bought complete with bellhousing conversion for 300.00.

box has been fine and i have abused it (as you do!). however last week i noticed my bellhousing has cracked through the mounting hole for the slave cylinder. not had it out yet so dont know why it happened.
made a braket for the slave cylinder myself not too much trouble.

made by company called dellow automotive (aust). i ordered a clutch fork from them by fax last year - received within 4 days. (65.00 inc carriage). if you need the number ill try to dig it out .
if you come accross a bell housing let me know!!
