Drivetrain JCW Turbo Swap
#77
In an effort to post helpful advice - K&N elbow will not fit. NM will fit (according to Jerry).
AEM site states there's is just for the S. However I do know of JCW guys running that intake.
The K&N intake pipe bottles down a little so I may have trouble sealing that end of the NM elbow and may have to buy their pipe.

Here is the stock one for the jcw. Less than $140. I was thinking of going this route or the Alta jcw inlet pipe. It's about $235.

NM coupler should arrive tomorrow. Will let you guys know how it fits

Update on the ebay JCW turbo. Turbo itself seems ok. There's still some odd surging under boost at high load and low RPM in 2nd and 3rd. Otherwise it pulls nicely and stays on longer approaching redline.
But being an ebay turbo, the inlet thickness is twice what a Borg Warner would be. So it needs a 2" coupler. The NM one did not fit.
So right now I have a standard 2" to 2.5" coupler connecting turbo to intake.
What I assume is the IAT sensor is now on a breather filter. The tube goes to my OCC anyway.
So if you get an ebay JCW turbo, get ready to do this.

Another option if you can be without it for a week or two (or pick up a rebuildable core cheap enough)
I sent a spare "S" turbo to g-pop shop they offered 3 services:
basic rebuild factory spec (349 or 399 don't remember of top of my head)
hd (I think this is their jcw equivalent) w/360 bearing, billet wheel, etc (basic +100)
And hybrid k03/04 $695

Not sure if anyone has noticed this but I am in the process of swapping in a jcw turbo. It was used and I'm rebuilding it. The waste gate shaft is badly worn so I was going to use my stock waste gate housing and saw this. The jcw manifold and jcw waste gate housing have a different exhaust port angle. So when I attached the jcw manifold to the s waste gate housing there was a step. See photos

Well I had the same codes and surging as Dr. Spade pretty much. I even had a tune put on my DME. I didn't rebuild the JCW turbo as it felt good(not much play) I think I will need to get a custom tune to get this turbo to work correctly.
I got this the first day, I went back and found my temp connector could had been not connected correctly and fix that.
Then reset error codes and had these come back. DME cut back boost to 5-9 PSI and after 4500RPM boost cut to 0 PSI.
I put back stock Turbo reset codes and was spinning tires with 18-20 boost because of tune of corse. So either I need to find someone that can custom tune to a bigger turbo or leave it be I guess. I don't want too.

I was able to buy the Accessport Stage 4 tune 10 minutes before Tigger called me. So I'll be swapping the turbo to the Alta 42/56.
I'm currently running the JCW turbo on that Stage 4 tune and it still surges and hits 22PSI. I did adjust the wastegate to open more as it seemed needed.

I had to take off the exhaust manifold; couldn't access the bolts holding turbo on.

That definitely takes longer. I will have todo that again once I get a replacement JCW wastegate housing. The used one I got was badly worn. The place I got it from are working on getting me another one. If that don't work I found a place over in England to get a new one from.

For the N14
The compressor side is different. But you can undo the clamp between wastegate housing and the cartridge(main part of turbo oil/coolent/bearing) and just replace that end of the turbo and should be fine. I did. I also got a K&N typhoon CAI and it fit the OEM JCW inlet. The other guy on here bought a China jcw turbo and it didn't fit to the K&N.
