I basicall need the exact opposite of this http://www.enjukuracing.com/images/fpradapter.jpg

Does that even exist or am i going to have to start making them? I want to run my stock fpr on an aftermarket high flow fuel rail such as the Yamato Garage or the Circuit sports unit.

Hahaha, nice.

No, you don't want to run your stock FPR. It sucks even at OEM flow levels, much less a high flow fuel pump/rail combo.

If you're baller enough for a -6an fuel rail, you should protect your investment/sanity and get a reputable FPR. Aeromotive is good, Sard is good, Nismo is generally not the best, FuelLab is new but has gotten great reviews. Real FPRs start at ~$100.

I use -6 line w/ a JGY fuel rail. Looks good and does a great job. If i were you i would get a good FPR. I had a SARD that broke on me so i just went with a Aeromotive one, if you going to do it, do it right and do it all. While your at it BigEnd makes a -6 AN billet fuel filter to that looks good with the setup and flows good. I love it.

That reminds me! Fuel filters are key, and most of the -6an stuff you find is either not a real fuel filter (it's a pre-filter) or else it doesn't screen small enough!

The best value I found is a Fram HPG-1. It's a paper replaceable element, screens to 10 microns, and has a very low pressure drop - all for ~$50.

Im going to be replacing my Injectors, Fuel rail and Fuel pressure regulator.

Ill be using this fuel rail

http://www.frsport.com/images/detailed_images/Circuitsports_FRK-NS13-WSK_03.jpg

With Deatschwerks 370cc injectors (stock size)

And also ill be using a Tomei FPR

http://www.frsport.com/images/detailed_images/Tomei_185001_05_15259.jpg

So from my understanding if i adjust the Fuel pressure to 43.5 psi (without the vacuum line plugged into the fpr) it should run like stock? Even with the high flow rail? Im not doing anything high hp and im running stock boost, I need to replace my fuel rail and figure id rather get this sexy one than another stock one. So will it run richer because of the rail or does the rail not matter and its all based on injector size/fuel pressure?

GSXRJJordan

10-08-2009, 08:39 PM

Im going to be keeping the boost stock. I need a new rail and would like to replace the FPR as well. Im already getting new stock size injectors. I wouldnt mind running a high flow rail and probably a tomei FPR, the only thing im worried about is can i make it run like stock with these two parts. Or should i just get a new OEM rail and FPR?

If you're keeping everything stock, you should just get another stock fuel rail/stock FPR. Going -6an lines will cost a ton more, and you won't gain anything from it.

GSXRJJordan

10-08-2009, 08:53 PM

If you set it for 43psi, it will run like stock.

Like I said in your other thread, you should just stick to stock and save the $hundreds.

lol what in the hell for if you're not upgrading everything else. And don't use douche works injectors.

ProjectGarage

10-08-2009, 09:02 PM

i need new injectors deatschewerks are the best for their money unless you know of another company that sells 370s for the same pricing. The reason im replacing all this stuff is because i need a new fuel rail a new fpr and new injectors so i figure why not buy baller parts in that field like i have with everything else so far.

garagelu

10-08-2009, 09:11 PM

370's? just get oem sr20 injectors. oem is better than anything out there ad cheaper too. You can get a set for about 100 dollars.

^fraktal^

10-08-2009, 10:56 PM

i know you made 2 threads for this basically. you don't need a fpr fitting for that fuel rail. that's the circuit sports rail right...? it already comes with all the fittings you need. they even show them in the other frsport pics where you obviously linked it from!

Yes they show the fittings you need to run an external FPR however my interest went to running that fuel rail with the stock "on rail" FPR. I basically want baller ass parts but i want it to run like stock or a little bit better. I am not looking to raise the boost or anything i just want good quality parts used for the fueling system.

ProjectGarage

10-09-2009, 02:15 AM

I basically want to run the circuit sports rail without the -6an lines since it comes with the regular fittings too. What i was wondering is if there was a way to hook up the stock FPR to that rail or if i can use an aftermarket FPR but still have it run like stock just have baller ass quality parts on it.

By this if you mean that you just want to throw your money down the toilet with no difference whatsoever go right ahead.... OEM nissan parts are "good quality parts."

Yeah nissan parts are definitely great quality. I would use a brand new stock rail and brand new stock fpr if i it didnt take months to get the fpr. I just want to know that the parts are going to last.

Are Deatschwerks really not good injectors? Ive heard alot of good reviews on their stuff.

ProjectGarage

10-09-2009, 10:09 AM

I agree, Im not trying to be baller with stock parts lol im trying to get "baller quality" parts which i know circuit sports is not which is why i may go with the Yamato one instead. Anyways I keep hearing more and more people talk shit about Deatschwerks injectors.. Whats the deal with that?

your engine has had those parts since it came out of the dealer and were still working until recently (i guess, if your changing them) i think that proves the lasting time of a oem part...

I keep hearing that z32 injectors are the same?? Im wondering if i can just buy them from a local parts store or what i should do? Its looking like im getting either DW or idk yet haha.

nsn240

10-10-2009, 06:21 AM

sr20 and z32 are both 370cc injectors.

Again, buy a set of injectors off the for sale section for $100 and call it a day.

ProjectGarage

10-10-2009, 04:33 PM

I need to get some 370cc injectors for my SR i want to buy them brand new but the actual SR injectors from nissan take about 3 months to get. So the only 370 replacements ive found are the DW ones. I need some feedback before buying them.

Thanks

Of course they're reliable. They're an extremely reputable company. Go look them up on different vehicles that they provide injectors for and I doubt you'll hear bad word of mouth about them. I bought there SR injectors and they've worked fine. I've had mine for a year already.

ProjectGarage

10-11-2009, 03:59 AM

Just trying to find any feedback on them before purchasing one. The main reason im getting it is because i need a new rail and this one will look sexy on my greddy intake manifold, Plus it does not have the extra tabs on it that the stock rail does so will be a lot cleaner!

Any feedback will be appreciated thanks!

Stock is more than you will need unless you are looking at 1000cc plus injectors, in which case its time to go top feed.

Fuel lines and intank pump is what is really holding back flow in the S-chassis system.

In that case, I would just cut and re weld larger an fittings on the stock rail.

Otherwise this is just show.

10-12-2009, 02:29 AM

Damn what is up with that stock rail? why does it not have the tab on the other side in the middle? Its supposed to have 4 tabs total.. Thats really strange.

Neither do the rails i posted pictures of but i was assuming that was because it is maybe for an s14 or something i hadnt really paid attention to that. But i have to have the tab on the other side with my Greddy fuel rail. Otherwise it will not secure correctly because i have to cut one of the other tabs off already.

Engine is an S13 SR btw.

Nope never seen one. I can totally see why you want to upgrade to an anodized fuel rail. It completely makes sense.

Seriously pull your head out of your ass. You have no reason to get one. Aside from wanting to waste your money so you can show all your ricer buddies how much you spent on a, useless for you, fuel rail.

Waste the money, but when you realize it was worthless, think of all the ppl who said no.

ProjectGarage

10-12-2009, 04:59 AM

Excuse me? Calm down bud.

Anyways i need to buy a new fuel rail either way so i figured id ask who was running one of these rails to see how it fit, how long they were using it etc.

I know the quality is not going to be as great as OEM (since nothing really is) Since i need a new rail and have to cut one of the tabs off for use with the Greddy intake mani, i figured this one would yield for a cleaner install.

Anyways Back to my last question what is up with the fuel rail that DRFTMARK posted, Note the 3 tabs on it along the bottom portion where is the middle tab that goes on the other side?

The one he posted
http://i12.photobucket.com/albums/a221/markfluko/DSC00206.jpg

The one that looks like mine

http://i227.photobucket.com/albums/dd132/s13pimp/DSCN2262.jpg

Whats up with that? I need one with the single tab on the opposite side since i have to cut one of the bottom tabs off for use with the manifold..

nsn240

10-12-2009, 06:40 AM

What don't you understand here? 3 threads??
You don't need a aftermarket rail, at all.
Buy a stock one, insert injectors, bolt it down.

No one cares that there's different tabs, there's still two places two bolt it down.
Stop making posts about this.

ProjectGarage

10-12-2009, 01:11 PM

You're right it does fail because nobody cares to put some knowledge into anything whatsoever. I sometimes wonder why i even post questions here. Basically if the rail is only going to be held down in two spots theres a chance it wont sit correctly and will leak.

nsn240

10-12-2009, 01:46 PM

The only unknowledgeable person in this thread is you.

use this - http://zilvia.net/f/search.php

Do you even know how the rail bolts on/sits in the IM? Do yo ueven understand how a Fuel Injection system works?? Two bolts would most likely be fine, if it's an issue than use the SEARCH button and compare fuel rails.

Not everyone is gonna hold your hand on stupid ass questions, you have a brain to use.

ProjectGarage

10-12-2009, 03:38 PM

Honestly I wouldn't. I would just stick with stock. Stock fits GOOD, DOES NOT LEAK. Why add some custom piece in when you don't need it that might leak? Bead blast and anodize a stock one if you want the bling.

This is the only knowledgable post in this entire thread. Thanks John, i felt the same way however i figured if either rail got good feedback i would go with it and stick with side fed injectors forever. Im not looking for huge horsepower numbers but youre absolutely right about the stock one i mean they put tons of testing into it why get anything else.

It does not seem like anyones using either of these rails so i guess that should be answer enough? I would buy the CS one if i trusted their shit more haha.

I have an S13 SR and im putting my Greddy intake manifold on and doing my mock up right now. I have noticed that when using the manifold with the stock rail you have to cut one of the tabs off of the fuel rail. No problem normally as the stock rail apparently comes with 4 tabs like so.
http://i227.photobucket.com/albums/dd132/s13pimp/DSCN2262.jpg
Well my New fuel rail that i have looks like this here http://www.frsport.com/images/detailed_images/Nissan_17520-52F00_006.jpg
Already it does not have the tab on the opposing side :squint And i still have to cut one more off of it which will make it look like this giving me only two connecting points. :rolleyes
http://i20.photobucket.com/albums/b211/dayoldbagel/fuelrailomg.jpg
It will be connecting to the intake manifold in these two spots.
http://i20.photobucket.com/albums/b211/dayoldbagel/greddy.jpg
I figured i would post this and see what others think, I can only hope that it will seal tight enough to not cause a vacuum leak or fuel leak. I wanted to double check with everyone here before i put my brand new injectors in the brand new rail before i realize that it wont work and have to basically break the injectors to get them out because side feed injectors are a pita to get out of the rail as we all know. :slap
So what do you think about this? Will it cause a problem? Any other S13 SR owners out there with the same type of setup? I just need some reassurance before i put it all together.

Basically, I don't feel good about that fuel rail you are going to put in

With a stock S13 SR fuel rail, you have to trim the corner off of two of the brackets, but you at least have 3 brackets mounting to the manifold (2 on one side, the ones you circled, plus one on the other side).

Not having ANY bracket on the other side....I agree with you....I feel like it might not seat correctly.....

EDIT: Oh yeah btw, you circled the wrong holes in your diagram....the ones it will mount to are on the bottom of the picture you posted. look at where the brackets are relative to the injectors.

10-13-2009, 08:22 PM

^ Well, if you got that to work, than that's good, seriously.

But I don't think that the OPs concerns are unfounded.

I could see how the rail might not seat evenly (flatly) into the washers on the manifold if there are only 2 bolts holding it down, and they are both on the same side (nearer the manifold, not the valve cover).

I would think that as you tighten the bolts, it would cause the rail to seat unevenly, so yeah....

rican_nick

10-13-2009, 08:37 PM

I had misplaced the spacers that came with the manifold (goes under the rail).. and without them there the rail wouldnt sit flat and actually lifts the grommets out of place. With the spacers there it sit's as flat as it can. Injector body sits all the way in and flush with the injector grommet. Goin on 2yrs now with no problems at all sorts of boost levels.

Btw, what did you do to your throttle body....did you just rotate the pulley?

I honestly do not remember. I "figured" it out 5-6yrs ago.

I had 4 throttle bodies at the time and I used parts off of one of them on the stock TB that came with the motor. The stock pulley put a retarted angle on the throttle cable that almost caused me to die downshifting on an offramp.. the cable got stuck.

Oh jeez...

My cable comes into the pulley at the right angle (left-to-right), but the point where the end of the cable locks in to the pulley is pretty far on the underside of the pulley.

...i.e. the cable wraps pretty far around the pulley.....I am concerned that over time, this is putting more stress on the throttle body.....my gas pedal feel firmed up significantly since i rigged it up on the new Greddy IM.

I may take the throttle body to a buddy and have him weld the throttle plate to the rod, right smack dab on top of the screws.....just to be safe.

It lines up with the pulley perfectly. If anyone else wants one lmk they are kind of pricey but you only have to buy it once so thats good.

all this mods to the fuel rail makes me wonder what i did wrong then.
im not trying to be a dick or rude at all but i had no mods to my fuel rail at all to run a greddy IM. i have no issues with fitment or anything.
also, i have a write up on how to modify your s13 sr stock throttle cable without have to get an s14 pulley or make custom brakets...

I ran mine none modified for years... bent one of the brackets up a tad and had to bend the stock FPR slightly to clear the TB. It was ugly but worked. When I decided to go all -AN I modded/powder coated it so it looked cleaner as there were not many cost effective options for a side feed rail.. and considering the bore on the stock rail is big enough for the power I was looking for there was no real need.
