Hello there,

Getting near the end of my swap (or so I think but never am as you all know the case) and I have seen an array of setups for Air Intakes and BOV/BPV. I was thinking of going with the BPV as I plan to recirculate it and was curious if MR2 and GT4 are the same functionally. I see they mount differently. Also, pertaining to the two inlets I have highlighted, some owners put little individual filters on these. Are there any drawbacks when doing this or reasons why I should have them go into air intake? The lower one I believe is a controlled vacuum leak which would make sense to be connected to the air intake but I figured I would ask around anyway for both. Thanks everyone!

the bottom hole your pointing too, hope you got the right one becuase that looks like the turbo water return port

Yeah otherwise use mini filters on them

Hi,

- on top is the OEM oil catch can, just mount a small filter (the oil dramatically reduces the ROZ of the fuel)

- buttom, is connected to the air box and the TB or in other words thats the line the ISCV uses to get air, further more the turbo VSV and power steering pump bleed the air to it, connect this line to
a line after the air filter

This guy has it.

You can also just put a small filter on the bottom one as well.
