86FC RX-7

my 88 turbo 2. Doesnt the 3rd gen come with 720 or 800's? What would i need to modify to put these in?

FD injectors are side feed, FC are top feed. FD injectors will not fit. However, I have no idea if you can swap fuel rails.

Would greddy 720cc top feed injectors fit? will i need a new fuel pump for this. Would the bosch 1000cc fit on stock rail? my guess is a new fuel pump for this. Im thinking about getting 720's and buying the rtek 1.7

DO A SEARCH

Stock FD fuel injectors do NOT fit without MAJOR modification.

GReddy 720's will fit if you file off the key tab into your 1988.
An upgrade fuel pump is ALWAYS recommended, no matter if you're running stock of large fuel injectors.
