My original setup was a front wheel drive VQ30DE running a ~95 Maxima ECU and harness. I should have stayed with that setup and got all the bugs worked out but I was having a persistent cyl 2 and 3 misfire that I just couldn't figure out. Right then I came across a killer deal on a FWD VQ35DE and tried to get it running on a 2002 Maxima ECU and harness but never got it to fire due to NATS system headaches. Lastly I switched that ECU to a MS2 setup running Ford EDIS ignition and finally got it running that way but never tuned. Shortly thereafter I got tired of being without a car for so long and parted it all out which I should have never done but hindsight is always 20/20 I guess!
What ever setup you go with I suggest a 350z oil pan and pick up tube, 350z rear coolant pipe and Z exhaust manifolds and intake manifold(if using 3.5L motor only) with manual throttle body from any vehicle, I used a Maxima one.
The easiest ECU to work with if using the VQ30DE will be the VQ30DE Maxima ECU, no security system to hassle with and easy to find harnesses to cut up.
Megasquirt is a long dark rabbit hole if you're new to custom ECUs as I was, I suggest avoiding standalones like the plague honestly although it's very capable among standalones.
If you're using a VQ35DE I suggest talking to Mark from Florida (PM me and I'll get you his contact info if you don't already know him) he helped me out tremendously on my project and was the authority at the time on working with NATS systems and VQ harnesses. Not sure if he's still into it but maybe.
Also, I'd look into the later 350z exhaust manifolds they are tubular like aftermarket headers and might clear the steering shaft.
Lastly, although I started this off with FWD VQ's and it can be a lot cheaper to do that, it's a lot more work and hassle to to do it that way and if you don't have any hookups at the salvage yard for example, it might not save you any money.
(A lot of that won't apply to your project in particular probably but I just felt like rambling
