I need to maintain 43+\- 5 psi in the fuel rail of my vit G16 at full throttle with stock injectors and a extra jet that has a 4mm hole in it. Will be using a vitara tank. If I make a falcon or commodore pump fit in the vit tank module would that work?

Any other ideas?

Does that 4mm jet have a flow rating(cc/min)? But yes a commo pump would flow more @ 3bar than a vit pump assembly.

In Oozuks thread he show a bosch pump that he used that was a straight swap. I used the same one on my comp truck.

Can remember what tank it suits though?

Possibly, I will have a look and see what I can find. I don't want to melt my motor so would prefer not to have to work off trial and error

Sticking a wet nitrous kit on a vit motor and the smallest fuel jet
Is a hole about 4mm, the structions say that it needs 43 pSi to work properly. Will have a look for flow rates

While I am at it is there any way I can arm a switch when revs are above 3000?

The only jaycar kit I can find is this one which I don't think will be any good to me.

The intank pump in a vit is somewhat of a generic 38mm pump, lots of jap cars run the same size pump and aftermarket high flow ones are available that can fit in pretty easilly

Thanks mate. Will the stock vitara injectors and pressure regulator be able to handle the pump when it isn't using nitrous?
