hi,
looking to get myself another impreza need a bit of info/advice,
seen a couple of nice classics and a nice p1 all the car's have had the engines rebuild by recommended specialists and all running a safe 330-340 bhp.
the p1 is x reg gearbox standard what is the safe torque/bhp for this gearbox.
the two classics are uk x reg same bhp same advice on torque/bhp.
thanks
bob

 

dpepends hwo they have been treated, i wouldn;t go about 340-350 max on either.

 

my last box lasted about 6 weeks t 360bhp odd but my new ones doing good

 

im running 350ish and 2nd day fluffed my standard uk gearbox so going newage 5 speed alot stronger
