The main party piece of the TCR/Clubsport/R engine is the IHI IS38 turbocharger. It is optimised to keep building power higher up in the rev range, where the regular GTI's IS20 runs out of puff.
Pros: builds power higher up
Vehicle:
Volkswagen Golf
IHI high torque starter and some sort of heat shield.
Pros: high torque
My car has been pretty reliable with an IS38 if you take away the issues caused by me or shitty parts (spark plug break after running past interval / Shuenk's POS), or the HPA HPFP that shit the bed after going with ethanol.
Pros: pretty reliable with IS38
Cons: issues caused by me
Vehicle:
Volkswagen Golf
I would suggest a ball bearing turbo like the vf52 and a protune. It makes it much more reliable and wakes the car up since it has the same engine and came as the sti, but a tiny sleeve bearing turbo that spools before the cam. I'm really happy with my vf52.
Pros: more reliable, wakes car up
Vehicle:
Subaru Legacy
Part number: VF52
it was ~40kmi, no crack, no shaft play or other problems etc.
Pros: no crack, no shaft play, no problems

Mileage: 64374 km
I got a new car a month ago that came with a IHI IS38. I got my tune from sneaky tuned and after about 2-3 pulls at 30psi the turbo popped. Spit the rear turbine out into the exhaust.
Cons: turbo popped, turbine spit out
Vehicle:
