RB20 Recirculation BOV Question

[CTblack240]

So I wanted to run recirculated on my BOV, problem is, I dont have another spot on my intake to run it. So what are my options?

Can I run a intake intake thing on the circled nipple and then run a recirculation hose from the bov to that original spot on the intake tubing like I drew? Lemme know

I'm pretty sure you want to run the recirculation pre-maf so the ecu can account for it. Other than that I'm no help.

Btw very clean swap.

No offense, if you don't know don't post...that's what confuses people.

Recirculation needs to be before turbo, but after MAF.

In regard to the setup, yes you could...you'd obviously need to adapt up to the same size hose from the BOV, but it could work. As far as the valve cover T, the proper way was to put another bung in your intake...but being plastic you'll need to get creative.

Best/easiest way is to put an aluminum intake tube and the bungs...if not at least run a hose from the T and have it vent down under the car (better than the valve cover filters that spray oil everywhere.

Stock bov is recirculated and there is a opening right after maf just before turbo on stock intake.

The stock recirculation piping goes directly to where that bov is to the stock intake piping (post maf, pre turbo) like its supposed to.

Figured it out guys, car never had a BOV? Didnt have a spot on the J-pipe there for never had one on the intake tubing. I bought a new j-pipe with a bov and now i gotta buy a intake tubing with a second inlet

Oops my bad. Looks like I learned a little something.

The pipe you have circle and the pipe next to it which is identical should be going to a Oil Catch Can you should not use these as points of Air Intake.

Left pipe on rocker cover should go to Plenum if you want or imo Catch Can, right circled pipe should go to the intake pipe in factory setup or imo catch can..

Then you can run your BOV into the stock location on the Intake Pipe.

You can do it how ever you like, but i would change the setup to suit a catch can removing blow by from going into your intake manifold or into your turbo hot pipes.

hey there should be a inch sized hole off of the turbo inlet pipe i have it on mine and thats where mine is recirulated to but i dont have a j pipe

I see a bit of misinformation here.

A short word to make the truth blatant at once, be it so:

1. The small fitting on the valve cover you have circled, should be connected to the turbocharger inlet pipe, that is, the rubber inlet tube that is clamped to the compressor inlet. And more specifically, it does connect after the maf sensor.
There should be a place for it there of similar size.

2. The bypass valve should go to the same place, that is, the rubber inlet tube, after the maf sensor. There should also be a place for it there, of similar size.


an explanation;

E1. The small fitting on the valve cover is designed to provide PCV to the engine during boost. The only place on that entire engine that can provide such a function without getting creative is the inlet tube between the maf and compressor.
In that place, there will be a pressure below atmospheric, during boost conditions.
