Hey all, I need some help please??? Im going to get my car on the dyno and tuned and ive heard that after its done my original gear box will eventually die :( Because of how much more power the car will get. So do u guys think ill need new gearbox or can I keep my original one? its a 2004 ba and I want the zf gear box from the bf.. Any suggestions would be greatful . Also one more thing I need to get my diff bush fixed has anyone else had the same problem? I went to ford and thet want $650 supply and fitted or $65 for the part.. All im paying for is labour so if anyone knows someone who does it cheaper please tell me .. Im in the campbelltown area. Thanks heaps Brendon
