Rb20 Afm Upgrade - Ideas?

[rory_kieran]

Hi All,

I just added a few mods to my RB20 which includes Fuel Rail, Fuel Pump, Dump Pipe, HFC, 3 inch exhaust, Apexi AVC-R Boost Controller, Air intake and Coil Overs (Best upgrade ever). Anyway, I was told that a upgrade to my Air Flow Metre can be really worth while and people use other nissans to do this. Any thoughts on this at all I would love to know more about it and if the results are worthwhile.

I appreciate it.

z32 afm would be a good and fairly cheap upgrade or if you wanna go all out i recomend the Q45 afm which would allow a fair bit more airflow then the z32

put a z32 afm on my rb20det. worked ok. wont make any more power but allows the ability to make more.

keep in mind you will need aftermarket management to run it

z32 should suit you fine but max out the stocker first, upgrading maf causes you to loose low end resolution...

As others have said, go for a Z32 AFM.

There is a group buy running on them at the moment for $330 brand new

Only replace it if you are reaching the stock AFM's limit. Remember you will need a remap or new ECU to use a Z32.

"upgrading" to a z32 AFM won't give you any more power at all

it is a necessary upgrade if your current AFM is flowing too much air to read. otherwise its a big waste of money

end of story

and with the mods you have, i'd be very surprised if your AFM is maxing out

dont bother with a z32 until your running a bigger turbo which is maxing out your stock afm

And less tuning resolution... so that is a very BAD reccomendation.

A Z32 AFM is a pointless upgrade unless your current one is maxed out

Plain and simple
