You could try 720's, but you'll need something like a SAFC to lean things out. The 680's from a GSL SE will also work. Check out this link: http://www.mazdatrix.com/c-6.htm .

Thanks for the tip I will reseach that. At a quick glance it sounds like the GSL-SE injectors might be perfect for what I want.

Yeah, 680's should be ok for your setup. Just make sure that you can use the low impedance injectors. That's why I sent you the Mazdatrix link. If your car doesn't use low impedance injectors then you'll need to wire in some resistors.

I think he should be ok. The 87 TII's had low impedence injectors, so the GSL-SE 680cc's should work just fine. I have them in my Project 86 with no AFC and they work fine But that is because it is a track car and uses alot of boost.

as long as your car was made before 6/87, the 680's will work fine. I have a couple extra laying around.
