kinda o/t but why are you doing that? do the normal 25 AFM's offer more scope than the GTR ones?

they are 80mm instead of 65mm and are good for about 250rwkw of airflow each so they are a decent upgrade

This should help you out mate. I found this on the net ages ago, I just did a minor edit to it in ms paint just then and added the rb26dett pinouts which I verified against the service manual, I thought that would come in handy on here so I added it. They are indentical to the rb20det silvertop pinouts as you can see. So all you need to do is compare the late model ECR33 diagram against the rb26 and change the plug accordingly. R33 S2 AFM's are pink label 3 pin outs, R33 S1 are green label 4 pin outs.

What I did with my R33 S2 AFM's was I took the top off them, un-soldered and removed the plug, then did the same with the GTR afm's. What you can then do is carefully trim back the terminals inside the R33 AFM's then screw in the GTR plug, then wire it accordingly inside using short wire and solder it. Then seal them back up again.

Its alot of effort to go to, but it means you don't have to cut the standard loom just plug and play.

Or just cut the loom lol.

thanks for the reply and info guys.

What i have noticed though is that each AFM has different amounts of pins/wires. One has 4 and matches the diagrams, but the other has 5 - am i going to assume this is also ground?

Cheers!!

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
