No you can't, not without some drastic modifications. The B4's turbos and downpipes interfere with the steering column on a LHD car. It was JDM-only, RHD...
You'd have to completely redesign the exhaust manifolds, downpipes, pressure hoses etc etc., or convert your car to RHD. More trouble than it's worth. The 'torque valley' between the two turbos is pretty horrible in normal use anyway. Many Japanese B4 owners have switched to a single turbo setup for more power and driveability.
