Catch can question

[i97supratti]

Question regarding installing a catch can on a turbo setup. Instead of installing the catch can inline between the intake manifold nipple and pcv valve, as you would on a NA car; you cap off the nipple on the intake manifold. You then, using the stock pcv valve, run a line from the pcv valve to the catch can, then to the INTAKE of the the TURBO. From there you run a line from the turbo intake to a 2nd catch can, and then to the valve cover breather right? Thanks, I made a pic to make it less confusing.




IS my drawing about right? For my catch can I was going to either buy this expensive greddy catch can, or use a DIY off cb7tuner, link here

And also how do you hollow out your PCV valve? I was planning on finding a fitting of some sort to fit on that valvecover with using the PCV valve. THanks.

you could do it this way, and you have to get a straight fitting instead of the pcv valve (or you can hollow it out).


or you could do it this way, by putting small fuel filters in line so there's no need for a catch can.

Cool. I might do the first one. I know the intake manifold gets pressurized under boost, so I figured I'd have to use the turbo intake to make a vacumn. I'll just drill thru the stock pcv valve and do #1. Thanks.

And also, should I spend the extra $$$ for a greddy catch can, or can I just use a homemade catch can pictured below:
