Just like the title says....who makes a larger set of rails for an FC turbo???
I'vesearched and searched and can only find stuff marketed to 3rd gens. Can I use aftermarket 3rd gen fuel rails???
let me know what's going on.....thanx

 

K2RD (is/was?) making secondary rails to be used with 1600's Bosch injectors

i have one for sale ;P

rx7store has them available I believe.

 

I just modified the stock secondary one.. you can drill it out and throw in some npt to AN fittings.. then drill out the injector whole to fit a larger american style injector.


I've got 1680cc injectors in the secondary rail.

 

That's looks nice.. any idea what the flow rating is???
And on that page you linked there is a rotor shaped dress-up piece for the alternators. How does that thing mount up??? kind of interested over here.

 

It's not only dress up but functional as well. It's a dual alt pulley to keep the waterpump from slipping when the airpump is removed. I have one and love it.

 

You shouldn't need a bigger fuel rail unless you plan to do more than 600+ RWHP.

The stock unit is fine for almost every application.

Now if you need 1600cc's then the rail which adapts to it would be needed.

 

well my setup will yield me about 460rwhp but I will be using 1600cc injectors with the set up to allow room for changing my map from street to drag on those special days.

 

Like i said. http://www.injector.com get the 1680cc injectors for ~$75/each

Then drill out the secondary rail to fit them. (Any machine shop can do this and should only charge $20-40)


NOTE: these should not be run with a PFC or stock ECU.. wrong impedance. Good with microtech or haltech though.

 

1600's are overkill dude..... If i had it to do over, I'd have put 1000's in the secondaries. I'm pushin 400 at the rear wheels and I'm not even using half of the duty cucle of the 1600's. You can get 1000's to fit the stock rails.

Well, i do have it to do over, and I'm going to run 720's and 1000's after the winter is over!

 

I'm going to be using a microtech setup.

 

And you will pay more for smaller injectors.. The reason you run the 1680cc injectors is they are like $75/each.

 

Will 720 cc injectors fit into the stock rails?

 

yes.

Keith is now making Primary and Secondary Rails for FC's. They are made for 720 and 1600cc injectors.

Keith is a good guy and is great to do business with...
