Tech dane! tech!

Anyhow, the crx fuel pump can support 450cc injectors @ a 75% duty cycle running 10psi, I belive they will start cutting out around 12psi or so.

I have a d16a9 and am looking to upgrade the injectors, i have heard it is a straight swap pretty much. Is someone able to confirm this for me, also will my car start with upgraded injectors or will it simply run lean then cut out? I am looking to do a turbo conversion so this is why I shall need the extra fuel what im trying to say is is there a specific order like turbo conversion 1st then injectors after? The car is off the road so daily running isnt required.....

if you have any doubts as to whether or not your stock pump can keep up, check out this link where a mustang pump was used in place of the stock in line pump.
