AFM Interchangeablility????
 

Guys,

I have an 88TII that ,yesterday, had its AFM crash. I have another AFM that I'm using. The only issue with it is that the little Denso part number sticker is missing, so i don't know for sure if it's correct. I've placed it on the car and rev'd it to 7000 with no breakup. My questions are;

1. Does the little stamping in the casting (just below where the Denso sticker normally sits) denote if its a turbo AFM?

2. What AFM's can be used as an alternative?

I have a track event tomorrow, so obviously the car needs to be completed this afternoon/evening.

TIA,

u can use a afm from a s4 na it will work just run a lil lean not to bad though. s5 has to have s5 though otherwise u wilkl run into throttle idle issues. the difference in the na n t2 is the resistence. if it runs with it u should be fine. i have been runnin a na on t2 swap for over a year now. im just runnin into the problem of the s5 t2 motor with the s4 na afm now in my newest rebuild

as long as its an s4 afm, t2 or n/a will get you by. its safe to use it

89-93 miata will work too, a little more lean than na though, i have been told. Do research though because i am not 100%.

I do know that the na rx7 afm is a popular upgrade on custom turbo miatas.

Thanks, guys. I'm assuming when you say it's safe to use an NA AFM is I can take this AFM to the track, correct? I have the Rtek ems, so I can see what the AFR's are doing. Any thoughts?
