Hey folks,

I have a second hand JCW turbo and i wont to fix it to my MCS.
I now it's a direct swap.
But are there any other issues?
Car is allready mappend (about 18.5psi)Sorry for the bad english, i'm from Swiss ;-)
btw the old Turbo is for sale (6000miles)

Regards

You're probably not going to notice much of a difference by simply bolting on the JCW turbo. Maybe a little, but I have a feeling you're not seeing the complete picture. You need to re-calibrate the ECU via Mynes, RMW, or Alta Access Port, and then you'll need the MAP sensor specifically for the JCW R56 S. I have a feeling you'll also need the JCW MAF sensor for everything to work properly. I would contact Jeff Perrin at Alta since he's doing lots of work with the Access Port and alternate turbos currently.

 

I thought the EU cars did not have the MAP sensor?

 

EU cars don't have a MAF.

You will pick up about 20hp/20trq simply bolting it on. You will need to get the car remapped for the new turbo to see the most gains. You will not be able to run more than 22psi as the MAP sensor will not allow it. Taking the MAP sensor from a JCW will give CEL's without the proper mapping in the ECU for it....something that Alta is currently working on.

In the mean time get it tuned for around 20psi and you won't have any problems

 

the jcw turbo will add 20hp/20tq just by siswitching it and nothign else? i say throw that sucker on myjector. how much HP/TQ can you expect with a tune from the AP?

 

Mine did.

Once the 22psi/map sensor issue is fixed, it will do around 250 whp/290 wtrq.

 

Forgot about the absence of the MAF on Euro spec. Lesson learned!

 

Thx for the feedbacks folks
This morning i have swap the turbo with now issues
And allready make a little round with the car, its helll faster
Map sensor for the jcw i have in stock and i will fix it with the mapper
He can remove all the CEL's included DP, psi will be around 20 - 21,5
Car is gonna be mapped 29 december

 

so did you ever take it to track and drag race it before the swap? it would be interesting get some #s to compare before and after.

 

I dyno't the car several times before the turbo swapNow it is 225hp with 330NmMods: JCW plugs, ITG panelfilter, Milltek catback and downpipe, FMIC, resenator delete and a custom mapping0-60mph 6.4seconds But i think the mapping sucks, i have a huge torque incraese and litte hp profitDyno run without mapping is 192hp and 270NmThe car is running 98RON V-power

 

Not completely true, euro JCW do have a MAF, my do anyway
Also Euro cars with the N18 (Cooper S) engine do have a MAF.

 

225hp hot bad at all. how does it pull on the top end? does it trail off around 5500 like stock or does it kep on going?
