The Rb20 hook up should be the same as the z32 maf if I am not mistaken. Check one of the stickies, there should be one on how to wire a z32 to a ca18det harness.

Thanks for the quick reply mate, i'll have a look

Just that a mate said in his 32 GTR he could use the RB20 AFMs as a plug in upgrade then his 26s, but the Z32 ran a different plug and they had to be grafted too.. so i am in a little hole atm.. but i guess getting it for free, me no complaaaaian.

and to check that it's okay, we're gunna plug it into one of his afm plugs, then run his PowerFC editor program on his laptop and check the volatges from it to see if it is the same as his brand new one.. arrrh !!Pete

I don't think they're the same, but I can't find any info on them either and I don't have any experience with it. Maybe you should go over and ask some questions over in the RB section. They might know better.

I do agree with Ryan, your best bet to be 100% sure, is to check the RB section.

I thought the RB20 MAF was only rated at like 240hp? And the RB25 at 310? I know the RB25 is the same as the Z32 for hookup...

That seems low to me. I thought the RB20 put out like 220hp in stock form?

the RB20 afm is bigger then the RB25.. it's a 80mm, but the difference between the 20 and Z32 is that the RB20 runs a higher voltage then the Z32..

was talking to Rory last night, and he said when he tunes his car for a Rb20, he gets around 390rwhp at 4.6 volts, compared to the Z32 where 390 comes in around at 3.2 volts roughly
