Riley,
What is your target HP number that you want to ultimately achieve? If its 400 flywheel HP or 350, whatever it is, even if it is 2 years down the road, check out RX7.com's website and under the fuel section for the 2nd gen use the fuel calculator and see what secondary injector size allows you to reach the HP you want at no more than 85% duty cycle.
1200 secondaries, according to the site, will net 428 flywheel HP, or should flow enough fuel to support 428.

well i have always been thinkin of just goinmg to 4 720s for now and then later on i would figure out the whole masive pump custom rail and huge secondaires. but i was just wanting some more detail on my options. like is the rp competition pump from rx7.com good to 500+rwhp as it says? at what point do i have to run all new lines and rails and regualtors? if i were to get 4 720s for now would i be able to send a couple of them off later to be bored out/flow more? can i do that with my stock ones now? i was just trying to figure out a way so that to prep me for whatever i get into later. i wdont want to have to replace alot of stuff if if/when i do get a big single. see what i am trying to get at?
