I know rotary performance offers a secondary fuel rail setup but how does it look installed anyone have pics?

Are you talking about a new fuel rail to run 1680cc injectors? that is an entirely new rail because the injectors it is made for are top feed where as the stockers are side feed. You cannot get side feed injectors that big so you have to change the fuel rail to run the top feeds. make sence?

well I really should know which set of injectors are the primaries and which are the secondaries first off forgive me for being ignorant. I believe the secondaries are attached to the lower intake manifold. does the secodary fuel rail replace the factory rail there or what If you have any pics that would really help

FikseRxSeven

yes it replaces the secondary rails, im pretty positive that www.kgparts.com have pictures in their site about them.



i think venom offers 1600cc side feed injectors now, but the 1300cc is readily available, kinda pricy though.



the drawbacks to switching over to top feed is, you have to get a fuel pressure regulator, hosing, fittings, and the injectors, oh yeah, not to mention a power fc or some sort of fuel management system to control the change in size

I already havethe power fc and datalogit system and a commander that I need to sell still in the box but I need to buy that other stuff and I want chris ott at rx7.com to do it but he is so freakin busy so no tellin when he can get to It I already have the 850cc injector and rp comp fuel pump I'm switching to the greddy t78 kit asap I'm just so sick of all he vacuum lines on the twins so I yanked the motor and and the twins are now sitting in my room with a bonez SS downpipe and either an apexi power intake system or greddy dual intake system I want $600 for all of it but I would take $500. anyway thanks for the links though If you know anyone who is interested in the parts then let me know. thanks for all the help.
