Nismo FPR??

[boyou2]

hi everyone

i just bought a new Nismo FPR for my rs13 with a ca18det engine,but i wanna know if it's pre-tuned for my stock fuel pressure,or i gat to do it by myself??

thx

IIRC they need to be set to your factory spec, since they are basically universal, in the sense that it was designed for multiple motors but retains the same part number for each

Pull off your vacuum source to the FPR. Turn the adjustment screw until you see 43.5 on your Fuel Pressure gauge (3 bar fuel). Reattach the vacuum line, and you're set.

You need more than just the frp. You need a guage that goes inline so you can see how much pressure your line has.

thx guys

i gat a gauge for that,and i know how to adjust,thx a lot,i just wasn't sure about this,if it's pre-adjust or not

buy ;)

Where did you get your gauge from? More specifically (I don't have a problem finding a 1/8" NPT 60psi fuel pressure gauge) I have a problem finding a way to tee it into the feed line. Did you do 5/16" barbed hose connectors into a 1/4" NPT tee block with a 1/4" NPT->1/8" NPT adapter for the gauge? Thats a lot of money on fittings for some janky gauge you're gonna use a couple times..

Now I did find this:

which comes with this:

Although the nipples are for 3/8" hose... Will the 5/16" hose fit over the 3/8" fittings? I think it will fit good enough to configure my Nismo FPR, then yank it out and run a straight line...

Thanks guys.

u can warm the tip of the hoses in some hot water to get them easy to expand then slip on the T. now where did u find that gauge, i need one for my car that isnt too expensive

Just look on Ebay for Fuel Pressure Gauge (1/8" NPT optional keywords), you'll find dozens. Jegs and Summit also sell quite a few. Might want to try to pick up a 60psi gauge, since the gauges seem to have a ~2% accuracy over the range. On a 100psi gauge thats +/- 2psi, and on a 60psi it's closer to +/- 1psi accuracy. No need for a 100psi gauge either since you only need to measure to 3bar/43.5psi.

Here's a link to Jegs I'm looking at right now... I think I'm just going to pick up my gauge and the 3/8" adapter from them:

hey codyace, i have a quick question. Is 43.5 psi the same setting for a redtop sr?

i got a Greddy fuel pressure gauge with all necessary for that(T,sender,gauge,etc...)

here in europe we are at 2.5b without the vaccum hose,on a ca18det engine.that's approximatly 36.75psi.that's in FSM i think.
