Which MAF?

[Slipstream]

I know you can use a stock, or Z32 MAF for your SR swap. But also heard you can use a Mustang Cobra MAF. Which version is needed though? 70mm/80mm? 19lb/24lb?

The real question is why use the Cobra MAFS. If you use any other MAFS than the SR MAFS on a swap you will need to have your ECU retuned or need an airflow converter of some kind.

I'm gonna need a retune or stand alone anyway, that's why I was wondering. I know most go with the N62 MAF, but I wanted to check my options.

If you are going to use a standalone just switch to a MAP sensor and forget this MAFS crap.

You could also use a late model Skyline GTS/Maxima MAFS (Pink sticker). It is good for medium level power, above stock, below Z32.
