Hi Guys,
I am using the T5 box, however I will no doubt have to rebuild this with a stronger gear kit at some point in the future.
I can fit either the T5 as is currently in the car or the RWD MT75 gearbox to my engine.
which gearbox is better after both have had a uprated gear kit fitted?
the MT75 is a newer box, and has a syncro on reverse.
any opinion would be appreciated, as I cant decide which to get rebuilt as I have an MT75 sat in my garage ad the T5 in the car.
thanks
Adam

what about general strength of the boxes, and strength after the gear kits have been upgraded.
also the gear change on both, I think from memory the MT75 had a quicker gear change but cant remember.
from a practicality point of the view the T5 is better with the removable bell housing. makes it easier to take the box out.

is the T5 really stronger once both have been rebuilt with uprated hear kits.
I know as standard the T5 is stronger, but is it after?

Its quite easy getting 400/400 from a boa.
Its safer going more 350/350 on the standard engine but i will be outting forged pistons in as this is the weak point really.
Essentially you just go either single or twin turbo with all other bits.
I already have the standalone ecu so just need to get manifolds and all ancillaries then just mapping.
I think it will cost me around Ł1250 to get about 350/350

better maintainability and ratios still doesn't make it a better gearbox.
it will be used mainly as a track car with limited road driving, so need the gearbox to withstand the stresses best.

but if I was buying stuff again I would use omex or similar. something more people are happy to map.
I only used that ecu as it was the closest place to me that did mapping down on the south coast that I knew about at the time.
the BOA/BOB will take around 10psi with standard internals giving between 300 & 350 depending on your install.
if you have a good mapper I have heard if you back off the ignition around peak torque you can then increase it again and then push the power closer to 400bhp. its all about detonation. get any detonation and the standard pistons will just melt, and by reducing the ignition at peak torque it will reduce the cylinder pressure and reduce the detonation.
