Ok I have checked fuel and I am getting it, checked Air and I am getting it, pulled the plugs today and despite them being 3 weeks old they are toast they look BAD!!! I have come to the conclusion that my plugs are wrong. I have the NGK IRIWAY 8 spark plugs. My motor is stock other then a headgasket, injectors, and a 3582R turbine boosting 1.5 bar. Car is tuned with a Power Fc and the tune is showing fine.

I have to crank the living crap out of the car to get it to start and when it does its blowing black soot all over the place even back fired but I am not seeing any knock on my knock meter its at like 5 knock which is fine.

The car reeks of fuel but the fuel pressure seems consistent, the fuel pump is active as well. I have to literally crank it and re jump my battery 2 times atleast before it starts which is not good. Do you think I need plugs? Oh and I know I need a battery now.

I am thinking I should tone down and go with 6's and trash the 8's.

What do you think?

BTW Motors an Rb25det

8's should be an ok heatrange for what your making but if they are too far gone to self clean throw in a fresh set of hotter plugs and see how they go

using coppers will make experimenting with heatrange a much cheaper exercise, always better to start too cold than too hot.

      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.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      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.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      boost source Size Garrett gt28 gen2

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
