AFM Question
 

Yo,

Does anyone know if the N/A and TII AFMs are interchangeable?

Nope, not interchangeable. Also, the AFM number needs to match the boost sensor.

if you look on your boost sensor and afm it should have a sticker on it. n318 is a 87 88 turbo part . n332 is jdm i have seen mix matched AFM and boost sensors...the car does run and idle fine just not reccomended (dont do it) they will not interchange between na and t2 ....on a side note the 86 87 afm should have n322 on them s4 and s5 are not changable between each other even if its turbo to turbo

s4 afm's are interchangeable (na and TII). you have to open up the inside and adjust the spring tension cause the na afm spring is just too weak so itll force you to run rich. if anyone has found a problem with this i would like to know, so far ive experienced no problems since ive done this mod

as for s5's i have not a clue. also s4 and s5 as stated above are not interchangeable.

Thanks, guys. Good information!
