So what are you guys with aluminum inlets doing for the high side? I didn't realize there was no port on the inlet to pipe the flapper side to so for now I have it VTA w/ flapper still in place, but would like a real solution sooner rather than later.

Any opinions? Low side is external + catch can, and I have a VTT breather valve to stop any positive pressure ATM.

I ordered a silicone coupler with a hole in it from amazon then ran a line to it so that it fed into the inlet on the rear turbo.

Get a fitting welded onto the inlet pipe? lol
My shop offered to have their fabrication guy make a whole new pipe with a fitting actually, but I was inpatient and wanted the car back quicker hence where I'm at now lol. I was more wondering if there were some creative solutions out there where I wouldn't be piping blowby straight into my shiny new turbos but I'm gonna guess not.

The general consensus I've gotten is leaving high side VTA is fine since its positive pressure coming out and the inlets have negligible vacuum, but I didn't know if something like Omar's solution could be made to keep vacuum. I've since messaged him on FB but I'm waiting on an answer for that specific question.

With a good catch can, it's not a problem. And vacuum in the intake pipe is decent under wot, depending on where the fitting is located/venturi or not. And with a vacuum draw is always better than just vta.

And a whole new intake pipe for a fitting?

Do you have a specific catch can rec in that regards? I know the BMS one is high flow and the popular choice but the baffling leaves a bit to be desired imo, and I have other things I wanna purchase before a full dual VTT CC or similar. I've never seen the inside of the VS or other common brand's cans so I'm not sure how the filter is for anything but the mishimoto ones, which I know they do also make one for the high side I just haven't heard much feedback on how it works there flow-wise.

And yes they offered to make a new aluminum piece with a bung, because they felt it'd be a cleaner solution than hacking up the regular MMP ones. The silicone boot solution I thought about too.

Yeah. I made my cc, as well as added a venturing in the intake pipe. Both high and low aside pipped in. No oil in my intake, all inside the can.

Also they make a bung type where you can add a bung into silicone (kinda like a nut/bolt setup)

Do you have any pics of your setup? I can picture it in my head but just wanna see it. I have instagram/FB if needed. Are you running check valves rather than a PCV valve too then? Ol' Robby seems to think piping both sides into one catch can can make your car self-destruct but I don't see how that could be the case if your PCV valve/check valve and flapper were functioning properly.

The local Advance auto also has a slip-over/joiner adapter for adding vacuum bungs to intake pipes too that I might make use of, I'm just not sure if it's well suited for Turbo cars or if it's geared more towards NA because it has 3-4 openings that are capped off and you insert your respective-sized bung into whichever you wanna use.

Ive ran all my cars this way for years with great success, from my 500hp e46, 900hp dsm, to my bimmer now. My intake is dry. Why do people try to reinvent the wheel when it comes to catch cans? This setup has been around for many years with great success on all my vehicles. I have both ade vc fittings, as well as plugged head ports.

I'm certainly not trying to reinvent any wheel, otherwise I wouldn't have made a thread asking for a solution. But I also didn't know if there were some lesser-known solutions (which I'd count yours as, tbh). But I don't know if I wanna wait for ADE parts that may be out of stock, and I have no idea how to make my own catch can or intake venturi.

I will however be running the high side back into the inlets with a catch can either way now, I was just curious on what my options were part-wise to accomplish it. Not all of us have the skills it takes to fabricate metal car parts, unfortunately, but I appreciate the picture.

Oh I was not talking about you in any way. That was just simply a statement is all.
