I just upgraded my head and cams, and i see that im running lean. The thing i was trying to figure out was what fuel psi does the b16a require? and also how do you test to see what your fuel psi is?

 

35-41 psi, this is coming from the b16 manual

 

get a fuel pressure gauge. i ran mine at 40psi.

 

I'm running at 46, Might want to set to about 42 or so. You don't wanna run lean.

 

a good 38-43 psi is good

 

where do i hook the fuel pressure gauge at? also can you adjust the fuel pressure with stock parts?

 

You can hook the fuel pressure guage into the service port at the fuel filter. There is a little bolt that goes in the top of the banjo bolt. If you remove this a guage can be put in its place. To adjust the pressure you will need an aftermarket regulator since the stock ones are none adjustable.

 

I have an AEM one and my firend install it and never told me how to change the PSI. How do I do it?

 

Ok there is a lock nut on the top of the regulator. Loosen it. There is a also an allen wrench type socket in the top of the stud sticking out of the regulator. After loosening the lock nut you use the allen key to adjust the pressure. I believe turning it to the right ups the pressure and turning left lowers it. Don't quote me on that. You should use a guage while you're doing this so you know what you are setting it at and if you are turning it the correct way. Good Luck

 

thanks for the help, seem easy enough. I have the fuel pressure gauge on the rail already so I am a go when I get everything together

Disconnect the vacuum hose from the fpr. A 3/8" nutdriver loosens the bolt. Use a 9/64" allen wrench to adjust. You're right! cw to increase pressure, ccw to lower.
Replace the vacuum hose.

 

Forgot about the vacuum hose part. It's been awhile since I've had to adjust my fuel pressure...Thanks for adding that.

 

THANK YOU BOTH
