FPR adjustment??

[bnollie]

Just fitted a nismo FPR and gauge to my sr20.

What Pressure would be best to set it at?

its running Standard injectors with a walboro 255 lph fuel pump

Also i was just adjusting it earlier when i put it above 50 psi the gauge starts to fluctuate up and down.

Why would this happen??

Thanks in advance

there usually set at 3 bar or 3.5 and as the revs increase the fuel pressure increases

Should be 3.5 bar approx, 3.5 with the vac off if i remember right.Then should sit at 2.5 bar with vac and go up to 3.5 under load.

3 bar with the vacuum off. You should have the car checked on the dyne to be sure the far is safe.

Dont alter fuel pressure on a car unless your mapping it..... 2.8bar @ idle
