Are you deaf or dim? Let me know which and I'll repeat myself at either a slower pace with smaller words or just with all caps....
Oh, let's just get it out of the way and cover both: IT CAN'T BE DONE RELIABLY!

As above. Might I suggest an Impreza or Evo as an alternative transport arrangement lol.
In all seriousness though if you insist on the "open turbo" you need to convert to either a MAP based ECU or one that uses either a hotwire or vane AFM (bearing in mind that if you are doing this for "more air" that any form of AFM is going to very slightly restrict the intake simply by having to hang it's own form of measuring instrument in the airflow in order to meter it, so the MAP is the more likely option). Not that the modification is likely to yield any noticeable gain since the turbo can only suck in as much as it's impeller size/angle & rotational speed (plus other design factors) will allow. So to sum up, if I were you & I was looking to increase performance I'd much rather spend my money on measures to (safely) up the boost such as larger turbo, higher flowing injectors, better I/C etc & only once I'd reached the limit of what the AFM based system was useful for would I consider going to a MAP system. That's just me however & if you really wanna do this just for the noise & look then your money has to go on ditching the AFM for a MAP based system. P.S. happy holidays cre
