unfortunately the 38mm qrj bpv wont fit the 38mm turbosmart flange supplied with the kit, i initially thought the same, but the design of the lip where the valve sits is different for the tial and wont seal properly.

i wouldnt recommend a bov like the tial q series because there is no way filter the air as its being sucked into the engine under vaccum, this could lead to dirt and debris being sucked into the intercooler pipe.
