I bought a 90 s13 hatch with a redtop SR a couple weeks ago. Basically, it idles really rough (sometimes stalls) when it's cold (after it sits for a while). Then runs and drives perfect when warmed up. I checked the MAF and the part number is:
22680 40f00
AFH50-04
That's the same part number as the maf I took out of my 89 coupe. I searched and and found this post:
SOHC 3pin 3whole plug 40F00
DOHC 4pin 4whole plug 53F00
SRs13 3pin 4whole plug 52F00
SR and SOHC are Hitachi, DOHC says nissan on top jecs on lable
SOHC and Sr look identical minus element plug
my 93 DOHC housing looks similar but the element looks different and the pins angle 90deg
Yes, SOHC mafs works on an s13SR.
A couple other people also said the single cam MAF works on the sr. My car is tuned with a safc I. When I disconnect the safc the car idles perfect, but then runs like shit if I try to drive it. I thought if the single cam maf is supposed to work with the sr, then the car should work without the safc.
It's a stock redtop with a greddy fmic, megan 3" turbo back exhaust and blitz bov (recirculated so it doesn't stall). Also has an safc, walbro fuel pump and an adjustable fuel pressure regulator. (I was told it was nismo, but there are no markings on it so I don't know). I get a code 55 from the ecu.
Can anyone confirm that the single cam maf actually works on a stock sr (like you run one and it idles and drives). Or do you have any suggestions for me?
I'd like to get a stock fuel pressure regulator, stock sr maf and remove the safc, but I don't want to do it if it's not going to make the car run better. I just want it to run like stock.
