sounds like a blowing exhaust manifold gasket between one of the manifolds and the heads
Nissan built an Impreza before Subaru, its called the GTi-R

dan could it be bad welds on the equal headers as i'm sure they've been welded badly looking at them and think there blowing have the un equal ones to go on but just wanted to make sure its not the turbo.

but its only there when actually driving the car?

is the car de catted??? when i got mine De catted i started to hear that noise.. the cat quietens it... it's very slight but it's from the turbo... i thought it was from the gasket from the down pipe but i replaced it with a new one but the exhaust is sealed fine.. just the noise my turbo makes! might be the same thing for you..?

The VF34 is a great turbo but totally wrong if its running a stock ecu.

yep, its ok as long as the boost is at a safe limit.

Starlet GT 1.3 forged engine, tdo4 turbo @ 1.25bar = 252bhp = SOLD :(

EDIT: Charade GTxx 993cc three cylinder turbo, 173bhp @ 1.4bar (should hit 200bhp with a larger throttle body, removing stupid high lift cams and a bit more boost)
