on an rb20det, only the rb20 AFM will work

if you want to change the AFM, then you need a different ECU that can handle the change in sensors

so if you have the stock ECU then the only AFM you can use is the rb20 item that was designed for the car. make no mistake, believe nothing else.

as mentioned, search "solder AFM" and you will find the answer to your problems of how to fix a broken AFM

We are not sure what your "obvious" AFM problems are, but I cleaned mine for 8 years by spraying with metho and lighting it with a gas lighter for a few seconds. -Maybe a bit extreme but it kept it going till I replaced it with a Z32 and ECU dyno tune ( Dr. Drift )

rb25det afms (green sticker) are identical to rb20det. They will be slightly newer than rb20det, but they are exactly the same (same part number and everything).

Upgrades for rb20det, 2 choices Z32 or Q45, both will require a remap. If you don't want to remap, stick with the green sticker rb20/rb25 afm

thanks everyone for pointing out the obvious thing that i didn't write the rb20/25 afms are the same.. which i obviously wrote in the second post

i got the impression this guy thoughthe could "upgrade" by simply putting in a z32 afm and drive away

i was trying to point out that this is not the case and he should be sourcing the same afm for his car that it already has

cheers,

Warren

    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
