1600, there was one at datnats with a turbo vg30 in there, i had a photo which im trying to find...

I don't believe you will fit twin superchargers and a VG30, in any of the smaller Datsun from the 70s.

Twin superchargers is silly. It provides no tangilble benefit over a larger single supercharger. You just end up with more frictional losses and a longer belt to drive them. Superchargers aren't like turbos, where rotational inertia is a big issue.

There are reasons why twin superchargers is not common
1. Long drive belt/multiple drive belts, complex tensioners.
2. Frictional power losses from driving 2 superchargers
3. Nightmare to make a manifold.
4. Underbonnet space
5. Parts Expense
6. Maintenance costs
7. Servicing of injectors depending on manifold design

I think it would look cool, but it's a hell of a lot of work, and you wouldn't enjoy the finished product.

If you want to stand out..paint your car flourescent Yellow, and put a big stereo in the car. Having a standout engine will cost you plenty in the long run.

Especially when Nisssan has already done all the fabrication you need for 1 supercharger...

what was the car that had the supercharged v6 as i have never heard of a factory one before

Here in the states the Xterra and another Nissan truck uses the VG33ER (R=supercharged). Roots type.

3.3 liter V6 and a supercharger -- future powerplant for my 1200
