Honda Automobiles: 2012 Honda Civic Si Project Vehicle Program

Reaching out to the import community, Honda invited three independent vehicle tuners to build and display their 2012 Honda Civic Si concepts at the 2011 SEMA Show. Tuners were asked to push the limits of performance and style with their builds, and the vehicles on display demonstrate the personalized potential of the Si Coupe and Sedan.

Honda invited the tuners to tell the stories of their cars, and those details are provided below.

Company Name: Fox Marketing Cars/Mugsy’s Repair
Vehicle Name: Fox Marketing 2012 Civic Si Coupe

Theme of Vehicle:
The main focus of this build was to showcase the reliability and performance capability of Honda’s new K24Z7 power plant. With a properly engineered turbo kit, the new Civic Si can consistently provide an enthusiast with over 450 horsepower without blinking an eye. Because the K24Z7 is so strong from the factory, we added a new Full-Race intercooled turbo kit featuring the BorgWarner EFR turbo as seen in Honda’s LMP1/LMP2 engine program and 2012 IndyCar teams. To properly and accurately tune the vehicle, Hondata FlashPro was selected to control Injector Dynamic 1000cc fuel injectors and the 255lph fuel pump, all made possible with the Chasebays Engine Harness. For additional power and durability, the stock plastic K24Z7 intake manifold was replaced with a Honda RRC intake manifold (euro Accord Type-R) sourced from ImportDPS. Since the car has these types of power numbers we need serious traction – so a 10.5 inch wide Vossen wheel with Toyo Tire will put the power to the ground. We then hand-built the widebody kit around the wheel and tire set up, and painted the civic BASF R-M Ultrasonic Blue Pearl, a new-school take on the classic Civic Si electron-blue-pearl. The interior was upgraded with Yonaka Ronin Racing Seats with factory Civic Si fabric inserts front, and rear. We hope you enjoy our vision for this new Si, and stay tuned to our Facebook and YouTube page for full dyno videos after SEMA!

Company Name: Tjin Edition

Name of Vehicle: Tjin Edition 2012 Honda Civic Si Sedan

Vehicle Description:
The Tjin Edition Honda Civic Si Sedan was built to showcase our abilities to build an overall impressive car that can be driven daily on the streets of Southern California. We wanted our Civic Si Sedan to be able to seat four comfortably (both adults and kids), while still incorporating our signature themes into the build. The interior of our Civic Si Sedan is customized in a black leather finish with purple diamond stitch, a full audio system and a pair of Recaro kids seats. The exterior of the Tjin Edition Honda Civic Si Sedan has been completely redone by the team at Daley Visual and Wraptivo. The exterior sports a custom wrap and carbon fiber front grille, roof, wing and rear diffuser. As the Tjin Edition Honda Civic Si Sedan rolls around the streets we wanted to make sure that people stopped and stared at the one-off 19×8.5″ and 19×9.5″ candy orange and candy purple concave Rotiform BLQ wheels and our Si’s slammed stance thanks to Function and Form.
