Cutting gas tank, doing side exhaust, adding rear diffuser.

OK so here's a couple of dumb question, because I'm dumb...

The fuel starve is caused by the saddle-style tank, so what you're doing here is actually cutting the other half of the tank off, reducing the capacity by half?

So I imagine that the passenger side bit of the tank is still in place, is there just empty space where the rest of the tank used to be?

I find this interesting because the gas tank in the 370Z is huge anyway and I actually only use half of it (because I can fuel starve the car even on the street when below half a tank just taking long off-ramps at a reasonably fun speed) so I kind of wonder why Nissan didn't just put a small tank in like this in the first place.

In summary, I'm not really seeing a down side to a 10 gallon tank and no fuel starve, especially if this were a relatively inexpensive (and still fully streetable) mod. Although it looks like you are removing a lot of evap/emissions stuff but that's understandable in your case.
