the legacy b4 was a beast from japan. i want to say that it had like 280 hp, but i really dont remember, i havent payed much attention to it.

 

i just know the car is amazing.

can I swap a 2000 legacy motor with a b4 twin turbo ?

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.
