Sorry if this has been covered. But I've searched and can't work out an answer.

I have a NA 300zx with a vg30de engine.

I have a bottle and feed line spare and plan to buy the rest of what I need from WON. But I still don't know WHAT I need to buy.

The intake for my car has 2 throttle bodies but they share 1 maf and 1 air filter.

Can I use just 1 set of jets/solinoids. Or do I need 1 set per TB? Obviously this increases the price a fair bit.

Cheers guys and girls

The two throttle bodies each need their own injector. With the VG30, you can probably mount a single set of Pulsoids in between the two banks then use a pair of Y- blocks to split the feeds to each injector.

Agreed and an even better solution is to use 2 pairs of Pulsoids, as a single set results in relatively long pipe routes, which has the following consequences;

1) A delay in the nitrous reaching the engine, which has the same effect as turbo lag
2) An even bigger delay in the fuel reaching the engine, which puts you at risk of a lean backfire, which can cause serious engine and even vehicle damage

These issues become more of a concern the more power you want to make, so single Pulsoids are OK to say 75 HP but dual sets start to be a more desirable option above that.
