Hi Guys,

Originally i purchased a greddy intake plenum for my rb25det to reduce the intercooler pipework etc. During this time i also purchased a nismo fuel pressure regulator (which is a direct fit onto the stock rail).

Once i recieved the plenum i realised that it is a much better idea to go for an aftermarket fuel rail as well, as i need bigger injectors (top feed is cheaper) and the stock rail needs to be modded to fit anyways.

I am looking at buying either a top feed greddy or HKS fuel rail, but neither of these have room to mount the fuel regulator on them (the ends seem to have screw fittings). It seems that you have to some how remotely mount the fuel pressure regulator.

Can my nismo regulator be remotely mounted somehow? or will i need to sell it and buy some sort of different regulator?

any help appreciated.

The nismo type A fpr that you have is only meant to install on the stock rail. If you want to get an aftermarket rail, you will have to go with a universal fpr like sard or malpassi. Besides with the universal fpr like sard, it has the ability to use flare fittings. Then you would use -6 lines and fittings for the fuel lines. The regulator will also need to be mounted somewhere in the engine bay.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
