Default WRX engine transplant-does it fix the 99MAF problem?

I'm wondering if doing a WRX engine or whole drivetrain transplant will fix the dreaded MAF sensor problem in a 99 RS because I am assuming you replace the whole intake manifold as well as the engine. Is this true or wrong?

with the WRX engine swap, you swap everything, engine, manifold, and the ECU. since you swap the ecu as well, then you need all the WRX sensors, including the MAF sensor.

Unless you swap in a 99 WRX which has the same Hot Film type MAF, only bigger

They've been saying that for over 2 years now.

Realistically... swapping another car's MAF in and adjusting the signal is the best bet I've heard, though.

The 99 WRX MAF has a much larger diameter then the 2.5RS one. Trust me. I had to order one because mine was too small.
