DOHC ZC larger intake/tb cause problems

I have a DOHC ZC with a full exhaust setup and a intake. I have a MSD Ignition kit coming in the mail. I got a great deal on a bored/ported n polished/port matched stock ZC Intake Manifold & a Billet TB. The bore is 74mm on them. Will this cause any prolbems air/fuel mixture? I also just found a deal on 4 PM7 injectors remaned. I have the PG7 ecu running. If I'm not mistaken the PM7 injectors should work fine with a PG7 ecu? Thanks, -Jim

yes they will work fine as for AF ratio u just gotta try and see BTW putting a bigger AF will not help to much unless u do some tunning....
