Thongvone Choumphimmasen: 1997 Honda Civic RHD

Thongvone Choumphimmasen's Uncle T owned his own auto shop and inspired him to build his own car. Choumphimmasen's first build was an all-motor 1992 Honda Civic CX with a H22 swap. "From then on my hobby turned into a passion," mentions Choumphimmasen.

In 2007, Choumphimmasen bought a 1997 Honda Civic EK in silver with a B16A motor. "I bought the car bone stock." The original plan for the Civic was to put in a fully built GSR engine, but a close friend of his convinced him to put in a K (series). "Before going to a K, I woke up one day and just decided to go all out and make it a RHD conversion," remembers Choumphimmasen. A week after going to paint, his dad left a huge scratch on the corner panel of the EK. "I kicked in the door in anger, and instead of going to fix it (a complete new paint job), I decided to get carbon fiber doors." But it didn’t stop there and Choumphimmasen ended up getting as much carbon fiber as he could find! "Things just kept on getting crazier (and crazier) for the build," recalls Choumphimmasen, "and I started adding on everything that I could find to make the car different from any other."

The RHD conversion was all done in Choumphimmasen's garage and it took 7 long years to get it to where it is today. It finally was up and running in 2016.

"I had given up on the car for a while due to not being able to find certain parts for the car going RHD," mentions Choumphimmasen. "After awhile of looking, I talked to Steve at Hmotors and he helped me find the parts that I needed." PFI helped Choumphimmasen build the motor and MoFab helped him finalize some of the things on the vehicle before he opened his very own shop. His friend Steve also helped him build the cage.

"Everyone inspires me to try new things and that’s why I do it. Without the inspiration of ideas, there wouldn’t be a build. My family also inspires me to go above and beyond with my build, and my son loves cars and says that it will be his one day."
