Guys, just curious if there's a quick route to some info on our MCS TD04 turbo's and how they compare against the ones found on JCW, or even from those N20 matched turbos off the BMW line-up. Lots of them all have the same TD04 designation, but does anyone know if those turbos are directly interchangeable to our normal S and vice versa? And do they have bigger/small turbine/compressor wheels, flow pattern, etc. Thanks for all the help.

 

Pretty sure the F56 S and JCW have the same turbo. The turbos in new 2020 JCW Countrymans and Clubmans will probably be different since they're pushing 306 bhp.

 

Coming from the gen 2 coopers, knowing there are two major turbo configurations in the same form factor, JCW and the S, makes me wonder if gen 3 does under go the same. It'll be interesting to see what the new Countrymans and Clubbies are getting on that turbo config to hit 306 bhp. I know tuning and some stock bolt-ons probably have a lot to do with achieving those figures under factory spec, I'm quite sure there are things inside the turbo which are also classed to run with the 300+ hp level. Still hoping to see if there's someone with enough knowledge or info to sort out all the different turbo configs within this very widely configurable TD04 turbocharger. And then we can see where our turbo's are at, what direct swaps we can do to upgrade with.

 

As of right now the S and the JCW share the same turbo. The main differences between the two are the JCW runs a higher compression ratio than the S. Now the new 300+ models and GP3 may have a different style of the turbo but it is entirely possible they are just turning up the boost and adjusting the timing.

 

I guess it use the same turbo as the BMW X2 M35iX
