I'm ordering the Greddy turbo kit within the next couple weeks along with a couple other goodies like a Nismo Fuel Pressure regulator. I will be running between 6-10psi on the turbo, so how much fuel pressure should I run? The nismo FPR is adjustable from like 34-80lbs and I will be running 370cc injectors for the time being. Thanks,

Brad

 

If your going to use the emanage that comes with the kit I think your stock fpr should be fine

 

 

I was just asking because I know that the e-manage system is set up for running 6psi. I'd like to be running 10psi. Do you think it would be worth my while to do the FPR and a walbro fuel pump? This way I don't have to go back and do it later. Thanks,

Brad

 

I would definetly do the walboro fuel pump but you should not need to upgrade your fpr

 

Yes.....i'm 100% with Kaion1000


your stock FPR is set at 43.5psi........and you should not need to up it at all ( unless your wanting 300+ HP )

I've got the walboro 255 fuel pump on my s14, and it works just fine, and will be all you need...

with that greddy turbo kit, your not going to push past 300HP any ways and your only going to run 6-10PSI so just get the walboro fuel pump

 

Thanks guys, I appreciate the help... I will need to do the FPR in the future tho, that won't be for a while tho :-)

 

driftingjdm240, I'll be running close to the same set up that you are, umm... have you ever gotten your car dynoed? If so, how much power did you put down?

 

ill be going to the dyno soon.......i hope to put down about 250hp........max..........if i dont get it...well time to get the T28BB......Right now i have a little problem with my oil return line...so i have get it fixed before i can drive anymore......ill post a video of my dyno in a few weeks.......

 

thats a pretty stout number, definitely wanna hear about it after your dyno run. Thanks for the help man.
