This fuel system I'm wanting to buy at rx7store http://www.rx7store.net/product_p/extremefuel.htm
only comes with an aftermarket secondary fuel rail and secondary fuel injectors. There's no primary fuel rail. Is this because the aftermarket primary fuel rail in S5 rx7s is sufficient, or is it just that rx7store doesn't stock a complete fuel system kit?
If that's the case, can someone point me to a shop that does?
I'm putting a t4 turbo in my car and that's going to increase horsepower by about 150 over the stock hp of 200.
Thanks

 

what supporting mods do you have for the T4?

 

microtech ecu, aftermarket exhaust, aftermarket radiator and E-Fan, and FMIC.

 

bump for an answer to my original question.

 

you dont need an after market fuel rail the stock rails are good way past your hp goals

 

your rails are fine but you are def going to need to upgrade your injectors. depending on how safe you tune your car but id go to around 1600cc secondaries and 1000 primaries. these number are also depending on how much power your looking to get. theres a power calculator out there you can put your numbers into and see what size injectors you will need.

also are you on the stock fuel pump?

here is one calculator and plenty of info.

EDIT
you might want to look into swapping your Pulsation Dampener to a banjo bolt. you can do a search for the mod.

 

The Rx-7store kit comes with a top feed secondary rail that are designed for Bosch style injectors with 14mm o-rings. To connect it to the stock primary rail you have to do this crazy loop-de-loop thing and clamp it on the OEM barb.

Why don't you just get injectors that drop into the stock secondary rail?

 

I don't want to have to do any modifications to the rails or injectors. If I can get injectors which fit straight into the stock fuel rails, I'll do that. Where can I get some?
If it's not possible to do without modifying stuff, then I'll get the fuel kit i mentioned above and modify only the primary fuel rail. Is there a write up somewhere on how to do that?

 

the main reason for the secondairy fuelrail is the elimination of the stock pressure regulator and a fitting so you can add an aftermarket one

 

what fuel injectors can you use with a stock fuel rail?

 

We can supply these injectors with 11mm adapters that will bolt right into your secondary fuel rail. We can also supply injector pigtails for the wiring. They are the same injector clip style as S5/S6 OEM injectors.

$240 for an ID injector with some basic clips?

you're high...

 

i make the fuel rails and other fuel related stuff..suuuper budget!

 

pretty much any top feed injector. there's only a few that i had to dremel down some of the plastic on the top end of the injector to clear so the injector wasn't getting sandwiched, this is going to be an issue with most injectors as they vary in height slightly, have larger and smaller o-ring seals, grommet seal area, yadda yadda. you just have to be creative. only need to change from the stock rails is to use larger fuel lines for say 500+WHP, even then you can run a paralell system versus series so.... yeah.

i thought about making rails for the FC but then i asked myself "why?". so there you go. might be beneficial for the n/a->turbo guys since the n/a rail is a bit more restrictive but the turbo rail flows just fine, the inside diameter is about the same size as most generic bulk injector rail stock lengths these companies are using. no offense. FDs need it to get away from the side feed injectors, FCs already use top feeds.

 

Injector dynamics dictates price, not us.. Where are they listed cheaper?

 

yes do tell where they are listed cheaper they are in violation of their selling agreement :P hows it going elliot? 1 day ill make it to your shop to say hello again

 

i could swear they were $200 last i checked.

 

tony @ http://www.t1racedevelopment.com is the main distributer for id injectors, whatever his pricing is...is pretty much what it will be unless you are friends of him or a few select others that can get them at wholesale price.
