Yes. Read the inlet thread above.

 

The inlet pipe comes with a seal that fits the JCW turbo. You can use the seal that is currently on the end of your stock inlet pipe, just transfer it to the JCW inlet pipe. That's what I have done and have 0 issues.

Side Note: You may want to upgrade the metal clamps around the inlet pipe to some thicker stronger ones!

 

Perfect! Thanks for the clarification. Mine is cracked and I don't want to take it apart to look at this point.

 

Thanks. That's what I thought. The "JCW" pipe being discussed here looks identical to the pipe on my 2012 Countryman S. I suppose the diameter could be different, but from outside appearances it looks identical.

 

Since my original 08 MCS pipe was cracking, I went and picked up the 1 3717 5824 53 JCW hard plastic part. I have the JCW air box (looks like the stock one) and it was a direct fit, rubber insert on the turbo side and everything. The only difference I found was in the original large size (airbox end) clamp, the slot is reversed for locating the clamp band. No big deal.

The part comes with the small hose that connects to the valve cover as well. Undid the clamp and removed it for direct attach to the OCC. Back in business.

Butt Dyno can't tell any difference yet on my short AM commute.

 

Any reason the JCW turbo wouldn't work with the N18 engine?

 

Don't see why not. Same MCS turbo is able to be used on the N14 engine and N18 engine according to Real OEM.

 

Yeah, I don't see why not, either. Was just hoping maybe someone had done the swap on an N18. But as you say, if the part numbers are the same for the OEM N14 and N18 MCS turbos, it's probably a good sign the JCW turbo will work on the N18.

 

In any case you will need to properly tune it to get all the turbo gains.

 

Yup!

Now for the question: Can you safely put a JCW turbo and a tune on an "S" without grenading the engine and/or trans? Thumper's experience leads me to believe maybe not.

 

Why I am the one who put it on his car, it worked just fine.

 

Hmm. I thought I read that he eventually had to rebuild his engine?

 

Remember that most people posting will be telling bad experiences, not really that all of them installing big turbos had to rebuild.
There are engines exploding? yes... how many? unknown of all of the modified universe.

 

I was running 22psi.

I would not imply that the motor blew because we put a JCW turbo on it. Keep boost no higher than 20, and absolutely run water/meth injection and I doubt you'd have any problems. Stock motors blow up too...sure the extra boost probably didn't help but I would not imply it was the sole cause.

The guy who bought my old R56 still has the JCW turbo on it and has been running it on the stock tune for over a year now...and to my knowledge he's had no issues. You'll pick up arond 20hp/20ft lbs even on stock tune

 

Thanks for that clarification, Thumper. You're right, of course; it is a bit silly to have suggested that a JCW turbo automatically equals a blown S motor. I appreciate the advice on how to safely run a JCW turbo.

Part of the reason I'm thinking of going with a JCW turbo is because I'm a little bummed about the lack of tuning options for the latest N18s at the moment. No flash tunes at all, and for the latest models (i.e., mine), only ETG and RennTech have confirmed that they can tune it. (I have an e-mail out to Jan to find out if he can, no word yet.)

Since a bench tune = voided warranty, I'm kind of toying with the idea of just slapping on a JCW turbo, manifold, meth kit, to go along with my Forge intercooler and Akrapovic DP while I wait for more/better tuning options.*

*I realize that, if found, a JCW turbo on an S would likely void a warranty just as fast as an ECU tune, but I think it far less conspicuous than an ECU tune.

 

I highly doubt any dealer would even notice...they won't look at the part numbers.

 

Exactly. To the naked eye, the turbos look the same. And, in any event, it's buried under the OEM heat shield which, in turn, is buried under my NM Eng heat shield. A tune on the other hand . . .

 

i wouldnt let etg touch it.

 

Aren't you the guy with the terrible experience though? Clarify me if I'm wrong, but if you are that guy, then how come I've found two people on other MINI forums with no issues on ETG's tune?

 

Can the N14 JCW manifold direct fit on the N18 S model? Any other parts need to change or used back the stock S parts?

 

Not sure. realm.com lists them as definitely different part numbers. There is a manifold for the N18 JCW. The cost is about the same. Why not get that?

 

I have check on realoem Wedsite the N14 & N18 JCW manifold part number is the same 11627593149.

 

Thats weird. I found a different part number for the N18 motor. But it looks like this may be universal.

WayMotorWorks has a manifold that says it fits both the n14 and n18 as well.

 

Yeah, I saw it on WayMotorWorks wedsite too.

 

Hiya! I i just found a JCW getting parted out. He has the Intake manifold, turbo and exhaust manifold. I'd like to swap it on my '07 MCS, but am concerned that the stock motor (I understand the JCW has upgraded guts?) might not work correctly? Are there any other mods/updates, or will the ECU and existing exhaust be compatible? Can I simply bolt these on and go? Are these the main components within the JCW system?

Thanks for your time!
