Can anyone tell me how much power the Impreza Auto box can handle? Also are the UK boxes different to the jap spec ones?

Thanks Ian

 

What is the box out of ?

If it is a 4E-AT (i.e. WRX Automatic) then it is apparently good for 300 bhp.

They use this box for drag racing in Oz....

Thanks

Gavin

 

Gavin thanks, I should of been more specific!
I am interested in all MY autoboxes, also do they hold the gears untill a set point ie: a sport mode! or is it a case of them changing up mid bend on you?

Thanks Ian

 

Ian,

The latest cars have a "Tiptronic" style auto box - the turbo cars before used the 4E-AT.

The 4E-AT is electronically controlled (has it's own ECU) and also dynamically shifts power between the front and rear - like an intelligent diff. It starts off with 60% rear / 40% front and varies continuously (ala Porsche 959 ).

It has a "Power" mode which is like a "Sport" button on most European auto cars (i.e. holds gears to redline). There is also a "Winter" mode (start in 2nd etc).

You can also manually select gears using the gear selector.

There is an e-mail group called WRX-AUTO at

 

Gavin!
