Here is a question that's driving me crazy with my build, and in general....
On the gt-4, is it ok 2 vent the BOV completly 2 atmosphere??
I ask this because I have noticed a lot of pics of st205s with a small hose that goes from the BOV into the airbox inlet, or aftermarket pipe that is designed for recirculation. Unfortunately when I received my swap, I did not get the airbox piece 2 connect my blitz dd 2....so I mounted it right off the IC outlet with a vacuum line on other end, as for my intake there are no hoses attached 2 it, just a big K&N filter on the end with a sensor after that in the intake tube. Is this ok 2 do, or should there be some recirculation from the BOV back into the intake??? And also the little black box that sits right behind the IC, that also shows a hose being plumbed into the intake, I just put a breather on that, is that a problem???

recirculate if u vent u run rich

205's use a manifold pressure sensor venting is fine I love the FIuuuuuuuuuu sound of my SSQV

if its a 3rd gen 3SGTE vent if its a 2nd gen recirculate

check out turboxs hybrid BOV's they recirculate first and also have two ports on the back side of BOV to also vent to "air" so you get both of best worlds....

Josh, If you're concerned you could use a forge splitter, but that is really just for the VW guys that have MAF sensors. They want a little of that blow off sound, but need to have the recirculation as well, but as was said before....the 3rd gen uses a MAP sensor that negates the need to recirculate. So at this point it's really up to you. As for the hoses being connected to your intake.....it wouldn't hurt to have them hooked in. It's not 100% necessary to have the one connected from the factory oil catch because some people change that out for an aftermarket unit. My question to you is," Where did you put your IAT?"

Ben, sorry i have 2 ask this but, the IAT, im guessing it goes in that area somewhere mounted right.......Holy Sh**, i hope i got it in my swap!.. what does the IAT stand for?? and look like

i dont have any pictures but it stands for "air intake tempature sensor" it is mounted in the intake tubing from where the air is coming in the engine ...its before the turbo inlet .. you should be able to trace it from there.. hope it helps

There are two different IAT's. Assuming a 3rd gen engine
