LS Swapped Genesis Coupe

CLOSING THE GAP

When your passion is your job, you can’t help but get excited about certain things.

In today’s world of Hybrid electric vehicles and near four-digit horsepower numbers from factory production vehicles, you can really do just about anything with an automobile.

At the recent PRI show in Indianapolis, I was incredibly pleased to see the number of manufacturers who continue to push the boundaries of what was thought to be impossible before today. Complete engine management systems and wiring made more user-friendly by companies like AEM Electronics. Safer solutions for fuel cell applications by Fuel Safe, with a complete line of ultra-lightweight cells and custom in-house build to your specification solutions. There was a ton of safety products, tooling equipment, and thousands of horsepower. I had the opportunity to meet some great people and establish relationships that will continue to grow as my career in motorsport and the automotive industry progresses. Coming back to Toronto having been kicked into high gear, I was anxious to get back wrenching on my own cars.

Driving a car that does exactly what you want it to do, when you want it to do it, and consistently, was my ultimate goal for this car. I originally purchased my Genesis Coupe new in 2012 and had already solidified my modification plans even before picking it up. I wanted a car that behaved like a new vehicle with all the tech and comfort, but could still throw down at the track.

With the drivetrain permanently installed and the suspension sorted from previous years, I was ready to upgrade my fuel delivery and get a bit more power out of the new 500hp LS3 crate engine. I decided AEM’s new CD-7 display and Infinity ECU would handle that job with ease. Utilizing AEM’s transducer pressure sensors for both fuel and nitrous oxide, monitoring the additional 200-shot will be a breeze with programable nitrous control and real-time bottle pressure displayed on the CD-7. An automatic bottle heater set to 950psi will keep the bottle at just the right temperature and reduce the risk of any catastrophic failures.

With the additional nitrous oxide, I needed a better, safer way to get more fuel into the engine where there was no risk of starvation or overheating while at track or spirited driving. I opted for a Fuel Safe 10 gallon Spectra-Lite cell which is the lightest in their fleet and of the highest quality. Mounted in an exoskeleton between the rear strut towers for better weight distribution with twin Bosch 044 pumps feeding the LS engine, there should be no shortage of fuel pressure.

To handle the additional torque, a twin-plate McLeod Racing clutch and flywheel were added to a built T56 transmission, a reinforced differential and a custom one-piece aluminium driveshaft built by Ottawa Driveshaft and Steering in Ottawa, good for around 1,000hp. The service from these guys was incredible, delivering the driveshaft in person on Easter weekend to meet my deadline. The morning of my attempted install, I realized I had ordered the wrong yoke, called ODS and had a Sonax chromoly yoke flown in and was able to get it to me that very same day.

With the rear-end complete, fuel cell mounted, and basic engine accessories in place, I am now plumbing the entire fuel and cooling system, nitrous lines, and getting the wiring situation figured out. The plug and play 58x harness from AEM is as straightforward as they come. A power distribution centre with five fuse-protected relays, flying leads for fuel pump, fans, and accessory power are included to make this harness especially swap friendly.

For the fuel, oil, and coolant system plumbing, there was no better solution than Vibrant Performance. Vibrant has been offering leading fabrication components, consistently growing their selection of fittings, hoses and clamping solutions since as far back as I can remember.

Working with larger AN fittings, it’s always a challenge to keep the hose ends from being scratched or damaged when securing the line. A proper-sized AN wrench and appropriate Vise jaw grips, plus a little painters tape should ensure a clean and tidy seal. Still to be completed are the feed and return fuel lines under the car, the remote oil filter lines and to pick a permanent placement for the Infinity and power distribution centre.

With high hopes for big gains and smooth power delivery, I am excited to get on the dyno and see how all of this will turn out.

I could not have gotten this far without the help of the team at Performance Improvements and the front counter staff in Etobicoke. They have consistently been my go to resource for the specialty tools and, of course, the parts needed to get the job done. A super knowledgeable group of guys who are all well invested in the performance automotive trade. If they don’t have what you need in stock, chances are they can get it in a timely fashion and handle all the logistics.
