is it possible to use a diffrent afm for a td0520g without going mafless as thinking of upgrading turbo but using an apexi ecu on an early wrx so heard might be able to use the z32 I think thats the one dont quote me any info or ideas guys

 

yes z32 is ideal.. fits same filter / induction size pipe etc and can be wired into powerfc and airflow curve is available etc..
