Happen to be talking to this guy who is about to carry out a twin turbo conversion on a 3.0RB last weekend.
He said he'd be using the WRX turbo's, small but enough to gain some good power. Said the engine is safe to run 8psi boost safely for everyday driving without touching the internals yet.
Guesstimate power gains he said would be easy 180-200kw ATW, conservative figures to say the least and about the $8k mark.
I dunno much about how much parts cost but does anyone know if this is a realistic cost? End to end, drive in, drive out.
Needless to say I am interested.... so will be dropping by more regularly to get updates.
