It will work fine as long as the air is cool. (I'm guessing you know how a MAF works, but for everyone else's sake) A MAF meter works by heating a wire to a particular temperature and then measuring the voltage required to maintain that temperature with the air moving past it and trying to cool it. The more air, the more voltage required to maintain the wire at that temperature. If the air is warm, then it doesn't work very well, since warm air won't cool that wire very well. In a stock turbo subaru setup, the MAF is pre-turbo, and the use of a bypass valve instead of a blow off valve, keeps the airflow measured by the MAF proportional to the air that actually enters the throttle body. Since in this remote-mount setup, a BPV would mean running another pipe all the way back to before the turbo (but after the MAF). That's a lot of plumbing, so you'll need a BOV.

But for that to work, you'll also need some kind of intercooling, which probably would be a good idea anyway. I bet an air-to-water setup would be a really great idea with this setup. Just stick one of these guys along the pipe carrying the pressurized air from the turbo to the front, and stick the heat exchanger up by the radiator somewhere. Would work beautifully.

You're going in the opposite order from me. I'm building the engine first and then turboing it after.

Tapani (since I know you'll check this eventually), where is your MAF at and do you have a blow-off valve? I forget.
