there is a link to the bpv (it is labeled bov on the picture). notice the design is very different from you're convential aftermarket bov.

i don't know if it is possible, but would moving the BOV "infront" of the MAS help to reduce the likely hood of running rich? if someone has already said that I apologize then for the repost. Are there kits that put the BOV "infront" of the MAS?

as for putting a BOV on a non-turbo car...No it wont do anything and even if it did your new name would Ric-a-roni

from all cars that i am familiar with, all the MAFs, AFMs, MAPs are positioned before the turbo, and the bov's are located on the pipes comming from the compressor housing. so to position it there would defeat the purpose.

Heres a pic of a Spec V turbo kit configured as I described... the recirc valve vents back into the intake AFTER the MAF but before the compressor..
Heres a pic of the Turbonetics turbo with the MAF metering the compressed air... Note BOV is between the MAF and the outlet pipe...
Likewide with the APS kit
In fact the only time you can vent to atmosphere with a pull through type turbo setup where the MAF is pre-turbo is if the ECU can correct for it... On a lot of factory turbo cars a MAP is used. In this case you can vent anywhere you want as the air is not metered as it enters the motor. The ECU checks the air by utilizing a pressure sensor in the intake track. This is the set up most Hondas use...I cannot speak to what MR2s use but all the pics I have ever seen do not show a MAF therefor it leads me to believe it is a MAP based ECU...Usually in high horsepower based kits where the MAF is before the turbo the MAF voltage is clamped and it is using a MAP sensor for tuning. If it does not you will most certainly have a rich condition when venting to atmosphere unless the ECU is somehow accounting for the air it already metered being expelled.
