Anyways.Just of hand only difference i can think of is the 135 would be pwg and yours ewg,thats if both engines i assume are n55b3000.
Few mods will need to be done regarding the original engine wiring harness,flash/code ecu,cluster,abs,diff and fem modules.
You will need the pwg system from donor.
The dct from the 135 is different to the m2 f87,so mods will need to be made.
You will then need the dct tcu,the dct shifter,the dct shifter will need some kind of mod to make it fit,cables,wiring harness,dct mounts with the brackets(will need some modifications to fit)the steering wheel paddles can be modified and retrofitted to your original steering wheel,the steering wheel wiring harness,dct clutches,and then coding/flashing of several modules to make them all talk to each other.
Dct cooler with brackets and piping.
You will need to remove/block clutch fluid lines,slave cylinder and master cylinder mod,and remove clutch pedal.
Your mechanic will need to check regarding the propshaft,i know the length is differnet on both, but the coupling he will need to see.
This is just off my head now,but the mechanic doing the conversion will have a better idea on what else needs to be done.
Its not going to be a simple plug and play.
The other option would be to use the pwg and just source another manual gearbox or get your existing one repaired and keep the car original.
Good luck on your build.
Thank you for the info. Is it doable to do b58 swap w zf onto the f22. I assume it would be from the m2?
