So this 350Z is going to be making heaps of power once it’s all finished up, but that power has to make it to the ground. At this point there’s no reason to leave this build with a stock limited slip, or even worse, an open differential.
The Quaife LSD was an ideal candidate for this application. It’s a gear style limited slip, so there are no plates or clutches that wear out over time. With power being put to both wheels at all times, this thing is going to be able to take advantage of all its 2JZ goodness.
This Z is going to stick to the road like white on rice with its new LSD and sticky Toyo R888 tires. This means high G-forces, which also means sloshing fuel, so the fuel system is going to get a little help from Radium Engineering. Their surge tanks are used to prevent fuel starvation when fuel is being sloshed around in the gas tank due to insufficient baffling. This tank is filled by the stock fuel tank and pump, and essentially acts as a second fuel tank that is always full of fuel. Since the surge tank will always be full, there will be no sloshing of fuel around the pump pick up during high G-forces. I’m thinking this 2JZ is going to be plenty happy with its fuel supply.
