Ok so just picked up a rb25 for my s13. Now it turns on and idles ok but after I drive it for a kin or 2 it starts to run rough and wants to stall out if u don't give it gas. Any ideas?

Could be a MAF issue but it sounds like you might be running atmospheric BOV. Recirculate the BOV.

N/m read it again but usually atmospheric bov problems cause the car to stall when after giving gas.

Its a stock bov and I don't have a exhaust but ibdont think that's a big issue. The mad is the n60 and I hqve a new z32 mad but I heard they run like crqp without a tune

Stock BOV need to be recirculated

But if the ECU in not tuned then the you have the wrong MAFS, If its a Series 1 you need a J60 MAFS, Series 2 Uses a E60

Is a maxima maf even tho its a e60 wrong for the car?

Try to check for some codes, does it blow out black smoke when it starts to run like crap? Maybe your ignitor is crapping out once the engine is warmed up.

Nah everything is good but this is a s2 motor. There is no ign chip. They are built into each coil
