HT81S twins undergoes engine transplant

Today Monster Pro-shop edogawa, Japan had posted a picture of a twin white HT81S undergoing engine changes to M18. This is very encouraging as this show the owner of HT81S still love their car and willing to spend more money on a 10 year old car. Both the car look fabulous and one are heavily modified with project mu brake system and carbon fiber bonnet. The one on the left are standard modified / light tuned.
Wait! Does this car both belong to Monster Sport ? Not an individual owner car ?
