Whilst swapping my pod filter back to the stock airbox i somehow managed to snap two of the screws sockets on the tip of the AFM, i managed to seal it to the box pretty tight but have a feeling air still going through possible gaps. I want to buy one of those second hand ones of ebay, most them are shown as pink label Rb25DET, are these ok to use on a Rb25de ?, little to no knowledge on AFM's.

from memory the natro and turbo AFMs are the same, so as long as you get the right model (3 wire or 4 wire) then it should be ok.

also, what bit did you actually break? i'm just trying to figure out which bit you broke and whether you could work around it

a little bit of an air leak on the airbox side of the afm wont matter, aslong as no dirt/sand/babies etc get in there. the air is still metered so it wont cause any issues.

unless you mean the other end (engine side) of the afm, in which case a leak is bad.

    • I’m here solo don’t have any hands to help so haven’t hit it with a timing light 
    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
