Have a 2009 jcw clubman.
Mods:
Helix intercooler
K&N filter
Noise maker delete
Mario Kart downpipe
Manic stage 2
Upgraded engine mount

I'm looking for the next mod to give more pop in the drive.
sprint booster?
pulley?
aquamist?
Injectors?

Please let me know. Haven't worked on the car in awhile and miss making a change.

 

I would skip the mods on your list, they are worth the money, in my opinion. What are you looking to improve? Handling? Performance? Style?

I have similar mods on my Clubman, and here is my short list:
Milltek or Magnaflow exhaust?
Rear sway bar?
Coilovers?
???

 

After improving reliabilty, my primary objective for mods is to improve driving fun. My Clubman is my daily driver, and I use it for autocrossing and an occasional track day, so I can justify almost anything.....at least without considering the cost. Some mods that I've enjoyed include a short shift kit (I run CravenSpeed), shift **** (have Doug Whalen and CravenSpeed), and an improved diverter valve (GFB DV+ here - will not add HP, but maintains boost when off and back on the throttle).

Some of my other mods include:

FMIC - Alta
CAI - JCW Kit Intake (my '09 JCW didn't come with it)

Noise Maker Delete – N18 Pipe
Lower Engine Mount – Powerflex

what is clutch interlock delete?

 

The clutch interlock delete is my description for eliminating the requirement to push the clutch to the floor to start the car. I don't mind having to do that, but I didn't like the extremely long clutch throw. Eliminating the interlock enabled me to put in a the clutch stop with many more spacers than I could have otherwise.

I think I became sensitized to long clutch throws when I drove my '03 330ci....it had clutch pedal travel out of a '55 GMC....

 

It allows you to start the car without pressing the clutch pedal.

 

can't you just turn off this requirement to depress the clutch to start the vehicle using NCS Expert like you can on BMWs?

 

Yes, NCS will do that. I had Code My Car do it years ago. This is a two stage mod - delete the clutch interlock and then put in a clutch stop to reduce the length of the throw. For most people, this isn't a high priority. I guess I'm fussy about ergoonmics.
