Hey everyone my rb20 runs kool just wants to die out when coming to a stop Ive been told its my MAF currently running a n60 would and n62 MAF work?? Please any help to solve this issue would be MUCH appreciated!! Thanks

Update!!! I got her to stay on at idle now it wasn't the maf like the guy said smh but I fixed a lot of boost leaks and now she stays on but now I have to adjust the timing because it's way to advanced! Thanks for everyone's help! It's been very help

Now if you have an rb20 oil pan that's in good condition let me know I need one lol

Do you have the blow off valve dumping back into the intake or did you ricer it out by letting it dump into the atmosphere?

Check for a vacuum leak, a broken hose or lose intercooler piping clamp. How many inches do you pull at idle? 15? 20? on the boost gauge.

Yeah you should be at least 19-20. You can build a tester at home depo. Google it and you will see what you need. Make sure to disconnect the PCV from the intake manifold to the valve cover when you do and don't put more than 5-8psi into the system.

If your ECU is stock and not running a SAFC thats setup for those MAFS then you are using the wrong one.

Stock RB20 MAFS are J60's

You can run the N60 maxima maf in place of the stock. The VQ maps are dead on with the factory maf. I think the S2 RB25 uses the E60 pink label one. Even that one is pretty close too lol.

Anyone got proof? voltage checks?

I just dont believe Nissan would would develope Two MAFS that produce the same Voltages just to use a diff connector.

I've heard the n60 would work to? That's what's one there now

You can search on Nico in the RB section it's well known. Also I changed the rom on another car I tuned to run the RB20 maf. I bought the N60 maf and plugged it in and didn't have to change the VQ map at all. It fired right up and got the same A/F reading as before.

Update I just found two kinked hoses and when I unkinked it the car idled high and then went to normal so in thinking its not getting the proper air flow when coming to a stop

Well I don't have the rb anymore but I did end up fixing the problem... The previous owner did a shitty job with the swap and had a almost every vacuum line leaking so I stopped the leaks and it fixes the problem
