GT Motorsports: 370Z Stock block testing, and turbo system development

Chris,

Just so you know a Twin turbo kit like the one GTM is offering needs equal sized turbos. Here is one of the many reasons why: Each turbo powers one side of the block i.e. turbo A runs off the right bank of engine exhaust gases and Turbo B runs off the left bank of exhaust gases. Having a staggered setup like you suggested would end up with one side of the engine fully exhausted while the other side would not be fully utilized. So in Lamens terms turbo A would be at full boost while Turbo B would not causing the right bank of the engine and turbo parts to receive much more wear and tear than the left. Not to mention that this would negatively affect any power you make as well as be a complete B*tch to tune!

Like I said there are TONS of reasons why this would not be a good idea... And many on here could correct me and elaborate further on the subject.

As far as your GT30 question goes I would say a stage 3 or 4 should do the trick! but remember you have to be able to feed this puppy too! so their stage 4 or 5 fuel system would probably be your best bet! Good Luck
