Pre vs Post intercooler BOV location and optimal air filter location
 

I currently have the old BEGI/FM kit sitting in my garage. The kit has the recirc BOV go directly from turbo outlet to turbo inlet in a very short loop. It also has the air filter position in the radiator location as pictured bellow.

Seeing how the newer version of BEGI and FM kits have the BOV positioned closer to the throttle body and have the air filter behind the headlight, this seems to be a more optimal design (which makes sense to me).

Because I will be deleting the MAF and using a speed density system I will be unable to use my current kit's turbo inlet routing without some modification. Also the two 90 degree inlets that the kit uses does not seem optimal for flow so I'd like to delete it. However doing so would remove me recirc inlet back to the pre turbo location.

If I add this to my kit for inlet, should i just switch to a VTA BOV near the compressor intercooler hot side, or add an outlet to near the throttle body for a VTA on the IC cold side.

Sorry, for the wordy post. Any feedback or other ideas to modify this kit?

I had a thread on this a long time ago.

Doesn't matter. Put it where its easier for you.
