Hey guys,

Noticed the other day while taking the car for a lil fang at round 4.5krpm+ while on boost and full thorttle "splutter splutter" coming from the back of the car. Just wondering if anyone else has suffered this prob before? Im due for a service soon but its only a fluid one so i doubt that has anything to do with my prob. Last service (6mths ago) i had Iridiums put in so i don't think that could be the cause, maybe coilpacks? Or in need for a tune?

Thanx in advanced.

buy 6 BCPR7ES spark plugs and gap them to .7 gap. see how you go

+1 to do that. does it mainly happen when its under load as well?

it may be your coils, try taping them up with some good brand elec tap and getting new plugs gapped to like.8 or less depending on how much boost your running. works a treat.

Hows it going mate. The same problem occured in r32 when i was running higher boost levels. Tracked the problem down to the wrong spark plug. I've happened to stumble across that the xr6 turbo run NGK Iridium plug with a .6 gap. Part number is BKR6EIX. Hope this sorts out your problem.

I'll be getting a service in a couple of weeks so i'll get the mechs to do a nice once over. I doubt the plugs would be gone as they're no more then 5,000kms old. Maybe need re-gapping its true, i'll keep you guys updated...please don't be coilpacks (crosses fingers)

95% its coilpacks...

sure way to tell is tape them up..

I had the exact problem and now its fixed with tape.. sure its a bandaid solution.. but its been working for the last 9 months so far

The reason regapping the plugs work is the gap is reduced... and seeing as the spark takes the path of least resistance it sparks correctly.

      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

      By GTSBoy · Posted

      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
