you need to make a plan and do your research, it takes to long to answer every hypothetical question. for example, fd3s uses different size primaries and secondaries and yes those secondaries are 850cc. Fc turbo II however uses 4 equal size 550cc high impedance injectors. you will not be getting 400hp on the stock injectors safely.

 

Holy crap this just saved me a bunch of time and $. I just happen to be friends with a rx7 guy. Thanks for the post

 

no problem, mine are still doing great.
