Turbosmart have released a semi-plumb back BOV, (dont know the official name) that vents a small amount to the atmosphere and plumbs back most charged air. This gives the sound (obviously not as much as a full atmospherer BOV) without stuffing up with the AFM.
However doesnt your RAV4 have a map sensor? If it does a plumb back is not nessessary as it reads pressure directly from the manifold and not before the turbo.
Just out of interest I did once see a sigma GSR without a wastegate and a BOV controling boost pressure. Not too sure, but i think the turbo only lasted a few months (maybe a tad longer) because shaft speed was astronomical. I suspect it was an expensive turbo too as usually only aftermarket pricey ones come without an internal wastegate...
