Been looking at a few STi's for sale currently but the claimed power outputs of some don't seem to stack up from what I can gather online.

One that I was looking at say there is a VF34 with an output of 380 bhp but I'm struggling to find anywhere online which states it's possible to get beyond 360 with this turbo.

Can anyone point me in the right direction or advise what else would of been needed to get it near that figure?

Would a standard UK 03 STi need any drivetrain work done when taking to 380?

 

A lot of scoobys claim big power but its all dreams (unless you buy from a memeber on here). I would stay clear of cars like this unless a bargin. If they don't know thier own rough power what else don't they know? Gearboxes can be a weak point cars with this power, the sti 6speed is better than wrx 5speed. I thought the vf34 was good for ~350bhp. Would ask a mapper for thier views. Would be best advice

 

03 STI on standard drive chain is fine with over 400bhp, Just ask any sellers for dyno results or ignore there figures. WRX is a different matter....

 

i had 360+bhp from my old Vf34 with supporting mods though...if you want more or a save 350bhp go for the MD321H from lateral
