ECU Tuning & Fuel Management - Fuel Rails

I drive a 2007 Civic Si (K20Z3) with full bolt ons (RH/R/ETD/TBS+G/etc). And I need some help with fuel rail fitment. I was wondering if any of these links below will fit alright on my engine. Usually K Series fuel rails will fit alright on my car wont they?

Will any of these fit...any help would be appreciated.

Why are you getting a fuel rail? Stock honda rails support over 300whp.

actually Marty I have seen Hondas with around 400whp using a stock fuel rail.

If your looking for HP gain, dont waste your money. If you just want one for the bling factor then go for it.

I believe almost all K series fuel rails you will need a custom -4 to -8 line to the fuel filter. Cheap and easy mod to do though.

Not looking for hp gain, and also not looking for "bling" lol. Im getting a 10lb bottle of nitrous for christmas, and I also am putting either the Kraftwerks or JRSC on in about a year or so. As soon as I pay off this car next Feb and get money ill be supercharging it

Can you show me a link to the fuel lines?

ok so now I'm confused. If your not looking for HP gain and your not doing it to dress your engine up then why are you looking to add a fuel rail?

Even with nitrous and a supercharger (which I wouldnt recommend from personal experiences) you still wont be making over 400whp and your stock fuel rail will be able to handle those mods. Just get an adjustable fuel pressure regulator.

I just wanna buy **** man. I wanna fix the car up but I cant find anything else out there that will either give me hp or anything else, so I was gonna get a fuel rail. I mean why not? If you have other suggestions roughly in the $100 range that will be more benificial towards a future supercharger setup; please, be my guest and throw me some links....

I was also debating on getting 1 step colder spark plugs after I get my exhaust Dec 9th...whats your opinion on that

what all do you have done to the car now?

what all do you have done to the car now?

Lemme see if I can remember everything...Ill be ordering an exhaust Dec 9th (semester ends), I currently have; Hondata Reflash, Vibrant RH, TBS and Gaskets, Ingalls ETD, Samco Hoses, Injen CAI, etc. Its a fully bolt on Si. Just no F/I atm...

If it helps, I dynoed a day after the header was put on @ 210whp (209.6), but dynoed it before I got the reflash. So dont know where im at now hp wise

I beg to differ, with what is listed mod wise on a tune I'd expect 215 to 220whp, with a jrsc and a small pully I'd say around 260 to 280whp and depending on the shot of spray it could get up near 400whp. The K's are crazy man, I just seen the other day a fully built/stroked K making like 402whp all motor

Only problem is there is still no real tuning available. I got a place near me called Swift Racing Tech and they completely built a K20Z3 Sedan and dynoed it to be 526whp. Lemme see if I can find the thread and vids for you guys

Heres the guys build thread - http://www.kseries-tech.com/forums/viewtopic.php?f=49&t=52
I dont know your guys policy of posting other forums but I just wanted to show you. Throughout pages 1-4 he posts pictures, and videos. Videos of dynos and drivebys are on page 2

i mean its your car so if you want a fuel rail then get a fuel rail. Im just trying to see you put your money to better use.

You could looking into your upgrading your fuel pump, you could get a aftermarket high flow fuel filter (I know they make them for the older Hondas/Acuras just not sure about the newer ones) you could also look into an adjustable fuel pressure regulator, maybe up grade your cooling with aluminum radiator (I know thats more then $100 but just making some suggestions)

cant you convert to earlier K series ecu's and use K-Pro?

What would the fuel pump of aftermarket flow fuel filter do for me exactly, whats the benifits out of it. I dont know anything about aftermarket fuel systems...an aftermarket radiator is thousands for my car, so that isnt going to be anytime soon lol

An aftermarket fuel pump isnt really going to do anything for a bolt on si...probably mess up my car if anything...

What do you think about 1 step colder iridium denso spark plugs

cant you convert to earlier K series ecu's and use K-Pro?

I dont think so. Someone on another forum is working on getting a dual ECU setup. And another person in Texas has tuned the ECU, but wont work on any ECUs delivered, he needs the car to by-pass the DBW and other problems we have with tuning the ECU

no point in going one step colder if your not FI and I only mentioned the fuel upgrades because you mentioned you were going to go FI via JRSC. Right now an upgraded fuel pump will do nothing for you.

List something that would do something for me right now, but will also do something for me later. I did also ask for an Exedy Organic I and ACT Prolite flywheel for xmas. If I dont get that I think I might just take $280 from xmas money and buy myself the flywheel..

if you don't know anything about fuel systems, why do you want a fuel rail? lol i know its been asked before, but idk, i guess i'm just curious

anyway, you're going to DEFINITELY need to replace your injectors, maybe/probably oyur fuel pump, and then the last thing that needs replacing will probably be the fuel rail. It all deals with supplying more fuel to compensate for all the air thats going to be pushed into your engine with F/I, although with no tuning program its going to be difficult. Also the one step colder plugs won't do anything right now. Once you're boosted you're going to want to run 91+ octane and always use one step colder plugs, but not right now.

Also Mishimoto makes universal radiator fans, which will help you, but you'd be hard pressed to find an aftermakret radiator for your car so soon.

Yea I just read about all of that. Injectors come with the kit, and I will be replacing the fuel pump but thats not for awhile

Soudns good. I think your biggest concern is figuring out how to tune, other than just re-flashing your ECU. Piggyback? Yeah, it sucks, but better than nothing.

And the money n the fuel rail could be spent on gauges or something (for example). Or just stored away for later parts (they'll sneak up on you).

I figured I would just save, but I havnt gotten anything huge for this car since my RH which was put on like 6 months ago so im going through withdrawl lol. Besides my reflash....I dunno, I just wanted to buy something to hold me over for abit more...

If anyone wants to throw out some ideas that will be in the performance category, please do so, im at a delima right now. If I cant find anything worth buying that would go well with a F/I appt then I suppose ill save, as much as it hurts haha
