To use the 440's, you'll need a stand alone fuel management like Idiot said. I don't know if they'll be too big, you'd have to crunch a few numbers to see exactly how much fuel you'll need, but a 3.1L would require quite a bit of fuel. If you want to keep the stock fuel management, I think using the SVO Mustang injectors would be good. They flow 370cc/min and are good for ~320 hp according to a Z guy that answered a few of my questions a long time ago.

I'm not quite an "expert" for n/a motors, but I think starting with the 370cc injectors from the SVO Mustang would be ok. The 370's will allow you to still use the stock ECU system of the ZX's if you have a turbo AFM and ECU. (I don't know if the n/a ECU's will work with such a large upgrade of an injector) Your idle will be a little richer, but you can mess with the a/f screw on the AFM to adjust it. If the 370's are too large, you can try the turbo injectors since they are still larger than the stock n/a's and there are a few of the n/a guys on zcar.com that have switched to them while still using the stock ECU with a turbo AFM. You could try asking on the tech forum of zcar.com or hybridz.org to see if one of the n/a people can give you more info. RC Engineering might be able to help too, they deal with fuel injectors.
