Do MSP's have blow off valves? If they don't can you install one even with all that plastik to0obing? Anyone done this yet?

Yes it does, it is a stock rx-7 BOV, it isattached on the right side of the engine(looking at it) it attaches to your hard pipe to the motor, and has a rubber hose back to the intake pipe. You can remove this rubber hose and completely block off the old fitting where the rubber hose went, and you will hear it a lot better. You can adapt a new one, either recirculating or open air, in the same location, you might need to change the flange though. hope that helps.
