Well dsm 4500cc injectors are cheap and easy to install.
Getting a btm would actually be benifitial and you'll probably make a little more power since you can run full base timing and retard it per psi of boost instead of retarding your timing via the distributor and throwing off all of your timing. Everything is thrown off when you retard your distributor timing (cam,ignition, injector's etc). All you need to retard is your ignition timing advance.
If you run larger injectors, the stock pump will be fine.
Another option would be to sell the v-afc and go with hondata. Or another form of simular fuel/ignition management. Much more reliable and you'll make more power.
