Hey Guys

(this is a repost from the rb30 conversion thread - really need the help)

I have got a R31 rebuilt/balanced rb30 botom end with a R32 rb25de head. I am having troubles with the loom and the injectors... So far I have soldered the plugs from the top feed R32 injectors onto the R33 wireing loom... This works a little (dont think that they are all on positive to positive, so I am trying to find a wireing diagram to figure that bit out).. but not the best at all (don't think they are all fireing properly). Any help with this would be great. But if thats not possible.

Is there any way to get the r33 rb25det injectors (side feed) to work on the R32 Rb25de manifold.

I guess im just after some sort of how to as to what to do to get it working.

This is all that is stoping me from going now..

Thanks

thanks for that meggala.

my problem is that I have an R33. I have put an rb30 with the r32 rb25de head into my car (old rb25 was playing up big time)

I grabed the injector loom from the r33 cut the ends off and soldered on the ends that came with the head (no loom just the heads). Now I am not sure if I have soldered the positive to the positive corectly and the negative to the negative.. Just wondering if there is a wireing diagram for this so i can check it out to make sure its all good... Also wondering what the impediance thingy is.

I don't think it matters which way round it is wired - it is simply running current through a coil to switch a solenoid.

Did you have the injectors on the "new" head cleaned up before you fitted it all together?

    • 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 😂
    • 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
