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?

 

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/v....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
