Hey I am trying to find out what else is needed to do a complete fuel installation. This is my plan I am only upgrading to secondary which is 1000 cc top feed american seal desgin injectors. My primary is goona be new ones from greddy. I am also planning to upgrade my fpr,to a-f type. This is my list of parts, keith secondary rail, fitting's,lines, a-f fpr, damper. Also does the factory harness plug into the the top feed injectors? khris

If your new injectors are low impedence (and you are using an ECU that required high impedence, like the PowerFC), you'll need resistors. And some injector connectors. And block-off plates since you'll need to remove the ACV to make way for the new secondary rail. And make sure the ECU you plan to use can work with the new injectors (PowerFC, any stand-alone). Chipped ECUs and piggy-backs won't work. I don't know what an a-f type fpr is.

That's a ton of work for an extra 300cc/min of fuel.

Why don't you just get your secondaries bored to 1300cc and put another set of secondaries in the primary rail? It's a lot easier (and cheaper) and will provide plenty of fuel any amount of air the stock twins will provide.

Well RC Enginerring don't recommend bore out injectors and other shops I call up they do not receommend it either, So ifigure since I am not pushing for big hp I just replace the secondary injectors, and buy new 550.
