You could try ringing up STechnic, they may have some advice as they deal only in subaru, mostly the performance ones (STi's, WRX's, GT-B and im sure the occasional B4). Have their own rally subby they compete in so yeah give em a ring and see what they say. If u remove the twin turbo setup, its aint a B4 anymore just know that :P I rather keep my B4 with its twins, makes it what it is
