compatable mafs?

Sadly, the n326 is the "pinnacle" of flapper door afm's. It is actually an upgrade for mk3 supras, corollas, and miatas.
The s5 afm (n370) can be wired to work, it flows more air than the s4 style, and the cone presents less of a restriction. However the s5 connector has to be spliced in, and the values are not exactly the same.
The cosmo afm (n390) uses the same plug as the s5 and flows even more, however it uses a different style bypass and cannot be run w/ the stock ecu. An safc could compensate for the difference, or an rtek w/ 720 primaries.
A MUCH better idea would be a MAF sensor, which presents no physical obstruction to airflow and still meters the air going into the engine (unlike MAP based ecu's). But you don't get the cool "filter on turbo look" and all the maf retrofits I've seen are a but pricey....
