Re: q45 maf install on ka24de (6902brad)
Why would you use a q45 MAF on your KA24de that thing isn't that thing like 90mm? I don't even think something that big with a lower CFM 4 banger would even change the voltage on the hotwire. Why not an N60? If you were going turbo and was trying to make 550whp maybe I could understand a little better.

yep, N60 came on the j30 and 89-94 maxima's.

yep, or an ecu tune wider diameter than the ka24de maf means that it will take longer to cool the hot wire. The hotwire also uses a larger voltage range than the ka24 mafs do....Neejay wrote:Even using a N60 MAFS, you'd still need at least a safc, right?

uhmm... these ppl that work on 240s everyday told me that theres no need to tune a ka24de if u install a q45 maf.
also, i heard that the q45 maf is better cuz its more sensitive and it be better when u tune ur ecu later on. i got an intake thats 2.75in diameter, and my maf sensor right now is like 2in. wouldnt be better if i get the q45 since its 3"? there would be better airflow right? im just sayin, correct me if im wrong...

Re: (driftfreek)
Let me correct your whole statement in a nutshell for accuracy.pay attention to the diameter of the stock s13 ka24de MAF, and then pay attention to the diameter size of the KA24de TB. The stock maf works as a restrictor plate, because it's diameter is smaller than the diameter of the stock TB.driftfreek wrote:uhmm... these ppl that work on 240s everyday told me that theres no need to tune a ka24de if u install a q45 maf.

STOCK S13 MAF 59mm
STOCK TB 66mm Inlet Diameter, to 60mm taper to butterfly
By changing out to the slightly larger diameter N60 maf you allow the hotwire to cool well while using the intake system as a velocity stack. A Q45 MAF is much to large to cool the hot wire and will only allow an NA KA24e/de to run rich because there isn't enough velocity per displacement to cool the hot wire fast enough. Really an N60 is all you need unless you up the compression enough to make lets say over 300HP NA donkeys.
