The ST with a remap, exhaust and better intercooler will not be far off an ED30 power wise but the torque on them is silly, having the 2.5 5pot from the volvo it makes its torque quite low down and just keeps going,
Plus the ST Focus platform is the same has the S60 so the awd system goes straight on with only small modification, The BSR focus ST is pushing just shy of 500bhp and about 450lb ft torque it also uses the awd system, its insane fast.
When I had my ST it was not really fast has standard but once the bluefin stage1 was on "claimed 271bhp" it was miles better then the milltek went on and the decat and the k&n genII then superchips downloaded me the stage2 with O2 delete
the sound is amazing like an old rally quattro. The only thing I didn't have to push it over 300bhp was the intercooler.
The new RS will be some weapon once remapped "claimed 341bhp and 545nm of torque" add to that a full tbe and decat and an even bigger intercooler
But then again you'll need to visit every petrol station on your journey
and id still rather have the Golf Gti
