its very easy.

All you have to do is either weld the BOV right onto the charge pipe, or weld a flange onto the charge pipe and bolt the BOV to the flange. Then hook up the vacuum line to the intake manifold (or other apropriate vacuum source).....provided the car isn't already equipped with a BOV or recirculation valve like its sometimes called.

thats why they're sometimes referred to as recirculation valves...b/c the air/pressure it lets out, it routes back into the pipe before the turbo, recirculating the air.

i would imagine the easiest solution would be to replace the stock bov with an after market one if that is what you are after. you would run the vacuum line off the oem bov to the replacement unit and let it vent to atmosphere. i'm not sure what the mounting looks like, if it is just a flange then just bolt on a different bov with the same flange pattern... if it is some weird bov that is part of the piping or something, then you could replace that section of charge piping with a fabricated one with a new bov mounted onto it. i have seen the toyota intercoolers that are top mounted (over the engine) with a bov flange welded onto the pipe section of the end tank.

pics would help a lot.

you'd probably have more luck on a toyota (MR2) forum....this forum is for hondas....so i doubt too many people know about MR2's.
