It's 3rd party, but then they modify it to fit the K04 hot side housing (bolt holes slightly different). Called today and they will be sending midweek next week. Annoying, as I had planned to have the car put together by this weekend.

 

As was done previously I'm reviving this thread as I've seen quite a few people mentioning buying JM turbos recently and am curious if anyone has any updates on their experiences with them.

Concerning the K04's, are folks running 2.5 cat less TBE systems with them or 3" catted/catless? Their site states to use a 3" system only but I'm guessing that's due to a catted DP being involved.

Just curious all around about these turbos and people who have them.

 

Had no problems with vendor or product. Great option for less than OEM price. Put 20,000 miles on my JM42 before trading car.

 

What's the next best turbo to switch to from a stock MCS turbo? Waiting on my DME back from Mariokart, stage II tune, but definitely want to move on to a higher stage in the future.
