Drivetrain Hybrid K03 Turbocharger
You know, sooner or later there will be wrecked JCW's. It's a matter of statistics and the fact that the cars beg to be driven hard. People will push the envelope; intentionally or not.

Thank you, I'll trust peoples insight who are paid to fix broken MINI's on a daily basis and see the motor's apart regularly.
You act like the JCW is some exotic vehicle...
No, it isn't. But there aren't a ton of them out there yet. We're just beginning the 3rd year and it has to be the smallest population compared to the Coopers and S's. The point was that they DON'T see many JCW's because it is still a small population.
...from your statement I will guess that these are MINI techs at a MINI dealer...why would they have the JCW engines apart on a regular basis? Removing the cylinder head for a carbon issue doesn't count either.
Your "guys" had the crank, rods and pistons from a JCW engine sitting on the bench next to the same parts from a standard MCS bottom end?
I doubt it.
Even if they did...they wouldn't be able to tell one from the other.
The operative word here is IF. I live in New York State, 240 miles from New York City.

*hint* there were no 2008 factory JCWs in the US.
I'll bow out now.

BACK ON TRACK
To help get this thread back on track here is an update to my k03 upgrade project.
I just received a call from the shop I sent my turbo to and they are done!
I had bought a MCS turbo off a salvage car with 15K and sent it to a turbo shop, I don't totally understand NAMs rules so I'm not sure I can say who. They rebuilt the turbo upgrading both wheels with larger units.
Once I have the turbo in, probably tomorrow because they are not far away, I'll take a few pictures for you guys. The shop said that they had upgraded many k03 but never to the extent of this turbo. I wanted the works, the total cost was $830 with shipping and my salvage turbo cost $700. I know I could have bought a JCW turbo for what I have paid but this turbo would be an upgrade for a JCW.

Curious it took almost a week...
It looks like they clipped the turbine wheel. Did they say why they did it? Also did they have to machine the turbine outlet at the wheel? It looks like the wastegate flapper is hanging over. If that is the case, how thin is the wall between the wastegate hole and the turbine exit.

Here are two more photos with my phone showing the exhaust side and space between the flapper and outlet.
My thoughts exactly.
If its possible to get this done at a cheaper rate or purchase the turbo itself for cheaper it would be worth it. A+ for a super stealth mod! I cant wait to see the final outcome, tune and dyno.
Also props to you for doing something differnt. It seems that a lot of people follow the same upgrade paths. Its only a few people that are brave and do something different. This could end up being a great contribution to the community.

It would still probably be worth it even at the gt28 pricing. This is a direct bolt on replacement. The gt28 would require you to have a custom made downpipe as well as intake tube correct?
Seems like this upgrade along with head PnP, a cam (I believe some are available now) and a good tune could make you some pretty good power.
I am definitely interested to see how large a difference this will make.

That is my game plan except will extrude hone the plastic intake and the exhaust manifold.
I have contacted Ken Newman about making cams a little bit more aggresive than the one Schrick offers.
I had an accident and never got a chance to install it, I need to sell this asap, please!

Work work work
I have been working like mad lately and not had a chance to install the upgraded turbo. I am hoping with the long weekend I will have a chance and take a few photos of the process.
Guess the next thing will be to find a local dyno. I don't have a before dyno run but I think we have enough info to guess at my before numbers. Do you guys think it's worth it to even dyno the car before I get a tune? I'm in Memphis if anyone has a dyno recommendation. Maybe just a dyno of before and after the tune, I really doubt I'll see a big power difference from just the turbo without a tune.

If you're not getting a tune for a while then do it! If you're getting tuned soon then just wait...and kill us all in the mean time with the suspense.

Oh and I'd drive it carefully until you do get tuned. At least have a way to monitor the boost. Did they do anything to the wastegate or actuator? If so things could get a little weird with the ECU. Car will go into limp mode ~27psi FYI....
Just saw you have a 335 now...awesome man! Jan tunes those too ya know?

I spoke to Ken today and he said they are working on them. I'll have them as soon as possible to test
Depends on how long before you get a tune...haha

Not sure how long it will be before I can get it tuned. Waiting to hear back from Jan.
27psi...
limp mode? I would think it would go into tow mode. I will probably have to adjust the wastegate, I'm sure they had to take it off and back on when working on the turbo. I have a 20psi boost gauge, never really thought I would run more than 20 when I got it.







I could have sworn there was a R56 JCW turbo on the NAM marketplace... it might of sold though
