if i get my injectors bored out to 750 primaries and either 1300 or 1600 secondaries, can i Still use the stock fuel rails?

thanks for any input.

 

what are you trying to get out of them... how about 850's all around or 850's primary and 1600's secondary w/ one of keiths rails?

 

Well if you bored out the stock injectors, then ofcourse you can keep them. Depends on what style secondary injectors you get, if its a different style, ie: nippo denso vs bosch, then you're probably going to have to get a custom rail. I am not that familiar with FD setups tho...

 

1300cc's is the max RC will bore the stock secondaries to. 1600's will require a new rail.

 

The 1300's cost me 3 motors... I don't recommend them thats not to say it happens alot but I've found 2 others that raninto a sticking injector that detonated my motor.

If you have access to the right tools, time and proper skills you could think about making a fuel rail. Someone left a link on a thread a little while ago of a place that sells bulk fuel rail extrusion.

You might want to check that out if you are interested in going up to the 1600s

 

Yeah, and they never have the Good (big) stuff in stock.
But when you get them, it's nice...

 

Where can I buy that fuel rail for the RE motor?

 

if you dont, you can click here. http://www.3rdgenrx7.com/keithsrails.htm

 

The only special tools you need is a drill press. Buy the materials and make one. I have a special drill bit that does it in one move but you can do it with three different bits. (actually 2 bits and a countersink)
edit: keep in mind that the 3rd gen and the cosmo use a different secondary rail.

 

And primary rail too

 

So, where can I buy that fuel rail thats already modified for the RE motor?

 

i believe crispeed made the one for the RE motor.

 

wow, $10 / foot -- that's hard to beat assuming you had the skill/tools to make your own...

and if you couldn't do it right, I mean you're out less than $30 I would think.

hmm, might have to look into this.

 

I tried PM'ing crispeed, but I never got a response. Is he around anymore?

 

He's extremely busy now. He doesn't make them anymore, unless you are willing to wait...

 

7 I know several people that have dropped stock 850s in the primary rail. It requires a couple extra washers to seal properly and that's about it. This is the route I'm going. Also, you can install an aftermarket FPR on the stock rail by tapping the hole on the rail for the stock unit to accept an AN line and and connecting it to the aftermarket FPR. Up the fuel pressure a little bit and this will give you enough for 400 at the wheels at 85% duty-depending on how rich you go.
