Does Rb20 Afm Fit Rb25?

[craig R33]

does RB20 AFM Fit RB25? my mate has one we can try to see if its my AFM that is playing up.

[chiksluvit]

which rb25? series 1 or 2 or neo?

won't work with series 2 or neo for sure

i vaguely remember that it'll work with r33 series 1 rb25.. not 100% sure, someone else might be able to shed some light on that

have you tried cleaning your afm and the plug connecters?

afms rarely break so you might wanna give that a go first, usually it's the oil from wet pod filters that go on the afm, or dirty afm causing car to not run properly

should be fine if you give it a clean

yeah im going to clean the afm tommoro when i change the plugs, will prob be dirty cos the old pod was very oily!

ill give it a shot,

also, would a dirty afm or dirty plugs cause the turbo not to hit its normal boost level? usually runs 12.5, but since this prob started, it barely hits 7 pound

[chiksluvit]

what kind of problems are you having at the moment? misfiring?

anything that causes your engine to not run smoothly will effect your turbo from spooling properly..

might still reach full boost however, just won't get there the way it should

if there's problems with your afm your car's most likely to stall, or won't idle properly

rb20, rb25 s1 and rb25 s2 are the same phyiscal AFM

the difference is colour label and rb25 S2 has 1 less wire (shared ground).

to use rb20 or rb25 S1 in S2 you need to duplicate up the ground signal.

the rest is the same.

rb20 - 4 wire - ground, power, signal ground, signal

rb25 S1 - 4 wire - ground, power, signal ground, signal

rb25 S2 - 3 wire - ground, power, signal

check my site for pinouts etc

check howto section for a thread cubes did on wiring and changing them

thanks paul, but that sounds way to complicated! lol, ""chiksluvit"" the prob im having can me read in my other thread "rb25 surging"

[chiksluvit]

rb20 - 4 wire - ground, power, signal ground, signal

rb25 S1 - 4 wire - ground, power, signal ground, signal

rb25 S2 - 3 wire - ground, power, signal

Thanks Paul for confirming, so ya the rb20 afm is plug and play on the rb25 s1..

ur car's s1 by the looks of it, so try on the rb20 afm and see how you go
