M20b20 and M20b25 AFM size same?

[bmcaz]

Hi guys;My engine is m20b20, stroked it to b23. Currently using b25 throttle body. Modified the intake manifold to fit the b25 throttle body. Am rebuilding the engine. The AFM hilang so i need to get a new one. Can i install a b20 AFM? I understand the AFM is the same but with different opening size which i can modify with some sort of coupling or connector. Please advise. ThankS

Wack a E36 328i unit at it or a Volvo unit. Not sure of the Volvo p/n but I can locate it if you want. I,ve got a 325is running a Volvo AFM partnered to a SMT6D piggy back unit. Makes the car totally different.
