Fuel Injector Upgrade Question
 

I've got a 93 rx7 13B.
Race ported
Aem stand Alone
t-78 single turbo
Downpipe, full exhaust
Planning on running 75 shot
Racing clutch, lightweight flywheel.
I was wondering what size injectors to get?
I saw a car with pretty much the same setup running,
720cc primary, 1600cc secondary. would this be good for me? If so where is a good place to get them?
