New to the Forum. Not new to Minis however, previous R53 owner. I have exhausted plenty of searches and forum lurkage to gather the information on my 2011 r56 MCS with the N18 motor. Heres where I think I finally need to reach out to the forum for help... Picked up this MCS a few weeks ago and has some fun stuff already done. My question has to do with the cold side charge pipe and why the the BOV has been relocated to the opposite end of the plumbing. I found that this Dejon company did not do mini stuff for very long and they are now out of business due to the owners failing health. I've found one thread with any information about this setup and was much help (https://www.northamericanmotoring.co...er-piping.html). If the engine was engineered to have a Diverter valve I would rather swap it back to that. Can anyone tell me what I'm getting into?

 

I can't be of any direct help to you here. Looks odd, but I'd suggest going to Realoem.com, plugging in your VIN last 7 digits and look to the parts pictures that illustrate the pipes and OEM setup of the BOV to see what the stock setup is comprised of.

 

Oh, I actually have what I believe to be a pretty good understanding of the plumbing of the turbo system. Thank you though! I guess I should say my question is more why this was done? & probably how it was done because that means theres probably a plug in the location where the stock DV was located, which I've read throws code unless programming is involved.

 

Noise. It's counter productive I'm sure. But some people just want a show.

 

I'm sure as well. I'm just trying to figure out how much of an undertaking it will be to get the system switched back to DV. Since it appears most of the aftermarket cold side parts are just the elbow out of the intercooler and the charge pipe that elbows back and down to the intake manifold, ill have to source the OEM plastic squished/pancake pipe also. And of course something like the Forge diverter valve kit. I really need to pull the bumper and see if theres a plug or what where the stock DV was. Sorry, just trying to get some confirmation from someone/anyone before I start sinking money into this endeavor.

 

Bump for any kind of help?

 

You know the original valve is on the drivers side of the motor toward the front facing the wheel, right? Is that all in place or blocked off some way? If you are having issues, stock might be the best place go. That would require changing out most all of the piping on the passenger side back to hard plastic where the black rubber pipe is. Then there is a rubber elbow that snaps on to it that goes back behind to the intake area. To save money, you might be able to source some of this stuff used or from a salvage yard.

 

The DV on my '07 MCS was part of the turbo --- directly connected to the single electrical connector. It's easily removed for upgrades. When my turbo was replaced by a Garrett, I added a BOV similar to the one you have --- GT28RS doesn't have a DV. Since there was no place to reconnect the connector, I added a 12 Ohm resistor at the connector to fool the ECU into "seeing" a load to prevent a CEL.

Don't know if any of this applies to the N18.

 

Thank you guys for the input. I've actually got a chance to get in there and poke around. It appears the stock DV is also in place. Now I'm really confused, is it functioning? Is it just there to not set off a CEL? Are they both functioning? Getting in a garage to do some other things this weekend and hope to gather some more information.
