So, I recently picked up this intake and I want to make sure I understand my options before I modify it. As you can see in the picture, it only has 1 bung/nipple outlet other than the bov recirculation outlet. Most of the ETS intake setups that I've seen have 2; one for the oil return line to be connected to the block and one for the vacuum line to be connected to the boost solenoid. I'm assuming the one that my intake has is for the oil return line since the nipple is fairly large.

Am I correct in my assumption that most setups have those 2 connections?

Is that the best setup for a basic bolt-on car with maximum plans to utilize a FP turbo?

How should I go about adding the nipple for vacuum line? Drill and screw a nipple in or have a bung welded?

And, out of curiosity, why would this intake be produced without the vacuum nipple? In other words, where would you connect the boost solenoid vacuum line to if you didn't connect it to the intake and what advantages would this produce?

 

Its only vacuum that goes back to the intake. Theoretically you can leave the vacuum lines that go back into the intake without ill effects. Some actually prefer no lines going to the intake tube when a 3 port is installed.

 

We use to have an option for boost solenoid or no boost solenoid. This particular pipe has no boost solenoid nipple. It's common when running an aftermarket manual boost controller to not have the nipple. The reason being the manual boost controller goes directly to the wastegate and vacuum source, there is vent port that recirculates back into the intake like a boost solenoid.

If you plan on sticking with the stock boost solenoid or upgrading to a grimspeed solenoid you have 2 options.

1.) You can vent the line that would normally goes to the intake from the solenoid and this will have no ill effect on the car or loss in performance.

2.) You can add the nipple to the pipe and recirculate it like factory. The easy way is to drill and tap a hole for the fitting or you can weld a bung in. The bung will make sure it doesn't leak.

Hope this helps! Any other questions, let me know! The intake now includes all bungs by default.

Thanks!
