Its another help thread from me.... So I got an extreme fuel rail and need to upgrade my secondary injectors, what are some good ones to get, im running a set up that will get me around 350 hp on a single greddy 20g turbo, 255 in tank fuel pump, and other upgrades. The other thing, is does any one know where I can get some good tow hooks? Thanks

 

which fuel rail, kg parts?

You'll need 160 lb/min (1680cc) top feed injs.

Also, if you are running a power fc you'll need to wire resistors into your secondary injecotor wiring for the 1600s.

 

What made you purchase an "extreme" fuel rail?

With that rail, you will also need an aftermarket fuel pressure regulator. You will also have to remove your emissions.

 

The rotary extreme fuel rail came with the car when I bought it earlier this month, and I just wanted to put it in, so basically "rynberg" you're saying that I won't pass emissions with it? and if that's so can I just leave the stock rail and injectors or what? I've researched this car for months before I bought it, however I'm not that familiar with the engine yet so thanks

 

I recommend selling the rail, it doesnt sound like you need it.

 

Also, I'm not looking to get as much power from my fd as I can right now (maybe next year's project) I just want to be able to run it all safely for now.... as both rails and injectors and lines are stock.

 

You will need more injector capability than stock to run that single turbo. If you have to pass emissions, then pretty much the only way is to get your secondary injectors (850cc) bored out to 1300cc by RC Engineering. For even more fuel, you can install the stock secondaries in place of the stock primaries (which are 550cc), which some modification to the primary fuel rail.

For anything under 400 rwhp, running the stock 550cc primaries and then bored-out 1300cc secondaries will be fine.

 

bad advice, sorry. I didn't see the 350 hp part. You can run the stock fuel system safely to 300 no problem. People have done 350 on stock injectors but I dont think it's too smart.

 

alright thanks, well the owner of the car that I bought it from said that it was never dynoed and said it gets 350 hp easily with the following set up...Engine, it's a jap motor (‘95 JDM)
w/ jacob electronic ignition box, msd wires, ngk racing plugs 9 and 11.5 heat range.
Walbro fuel pump 255 lph
Oil cooler, there only one, but it's a Morosso 11"x9"x1.5" w/ all
-10 stainless lines and A.N. fittings.
The V-mount set up is: the radiator is a Koyo, the inter cooler is an
Evo 8 w/ Precision turbo elbows and tubing.
The turbo kit is a Greddy 20g w/ 50 mm racing gate

so was he overestimating? or do I really need a fuel injector/rail upgrade here? thaanks again

 

YES. What ecu is on the car?

 

the power fc

 

i would like to see some engine bay shots. preferably the v-mount. it sounds like its a custom setup which i will be doing in the future...

 

Here is a link to the fuel rail install how-to:

Thanks guys so far again, I think I'm gonna take rynberg's advice and get the secondaries bored out to 1300cc to make it pass emissions right now, and I will post an engine bay pic as soon as I can, but if you guys got anything else that would help let me know and thanks again, you've been very helpful again

 

Here's a general shot of the engine with the V-mount set up right after it was done (the engine has been cleaned since then!)....this is for "silverTRD" and let me know if you want any more specific shots.
