i was just curious as i am able to pick up some 350z injectors. Guy says they are 03-06 g35, 350z injectors. From what i read our injectors are 315cc and the 350z are 335cc. what im wondering is will the 350z connector fit the harness of an 03 maxima?

They will bolt right on. I have some.

Ok thanks Nmex that basically all i needed to know. Let me ask you your opinion. I have the CAI, gutted precats, ssim and ported u and lim, ground kit, and i will have a new SAFC2v soon and will be getting at least a 2.5 inch exhaust come spring. Once i get the SAFC i will do the BBMAF as well. From my reading adding fuel via the SAFc retards the timing . My thought is to get the bigger 350z injectors and be able to pull fuel to lean it out and add timing. With all that i am gonna have (no headers in future as far as it is now) is it a waste to even do the 350z injectors or is it a good idea and will it give some added power over everything else?

It's a 'ghetto' or 'poor man's' way of 'tuning' (probably shouldn't even be considering a tuning method), but, at the time i was setting my car up, it was the easiest and most 'available' option around. So yeah, sure you've got all the accessories (WB, and soon to have BBMAF/SAFCII).

I got mine for 90$ shipped, you could probably get them for cheaper these days, since I got mine a long time ago.

Correct me if I'm wrong, but these are the purple Z injectors, no? I've been thinking about doing this for a while...

So does this do anything at all in terms of power or just more gas wasting? Also when you say bolt right up does that mean really just bolt and go or is there anything ECU or other related that needs tuning?

The use of Z33 injectors on a N/A Maxima is a way to make the car run richer and then tune it using an airflow based tuning device. (ie SAFC). Since when you pull the airflow signal to lean the AFR back out, timing is indirectly added, the more airflow you pull, the more timing you add, which is why Z33 injectors make sense.

If you use a program that has a separate injector & ignition harness, you don't need this.

damn you motherfuc*ers are knowledgeable, this is why i love max forums. you think these would fit on a 00 or only 02-03, im thinking only 02-03 bc thats the VQ right?

DEK's already have Z33 injectors, the fuel pressure(FP). is just set lower.

In order to take advantage of this 'method' you would need to up your FP.

All Maximas 95+ have VQs...

This.
