But there was a problem. Nobody Tim could find had ever installed a GReddy twin-turbo kit on a G35 sedan. These kits were designed for the 350Z and G35 coupe, but after sourcing the kit from a vendor on G35driver.com he removed the Stillen supercharger setup and took the car to UMS Tuning. “The install went great,” Tim says. “There was very little modification required to fit the TT kit on my sedan. Things were tighter, the turbos were millimeters from touching the frame each side, but it fit. We installed the UTEC, boost controller and it was time for a tune.” Tony worked his usual magic on the dyno and the twin-turbo G sedan now pumped out a very healthy 405 whp and 399 ft-lbs of torque on Arizona’s “finest” 91-octane fuel. With his 400-whp goal reached, Tim thought he was done building his G. Yeah, right.
“I enjoyed the turbo kit a lot longer than the supercharger, but after about a year the G was feeling slow again,” Tim explains. “I knew that eventually I would have to rebuild the motor, so why not do it now? I was only aware of one other G35 sedan with a built motor and its power numbers were not very high due to small turbos. Sweet, time to become the highest power G35 sedan around!” To achieve this new goal, Tim sent his G to Kevin Nichols at Nichols AutoFab in Prescott, Arizona, to do some custom fab work.
Tim always liked the dual exhaust system that the G35 coupe and 350Z came with, so he relocated the fuel evap system and made the necessary modifications to fit a second muffler on the passenger side, while Kevin built a custom 3-inch dual exhaust. Kevin also customized the 3-inch downpipes and routed the wastegate dump tubes back into the exhaust to keep the sedan’s exhaust note as subtle as possible.
Meanwhile, over at UMS Tuning, Tony was building the killer VQ block of Tim’s big power dreams. With fresh heads from GT Motorsports to go along with Wiseco 8.8:1 pistons, Tomei rods, Cosworth bearings, JWT S1 cams and valvesprings, the reinforced block was ready to rumble. After carefully breaking the engine in on the street, Tim then returned to UMS for yet another dyno tuning session. With the Walbro 255-lph fuel pump maxed out, Tim’s killer G sedan pushed an amazing 538 ponies to the rear wheels. Not too shabby, but Tim wanted more and to achieve this some fuel system upgrades were needed. That’s when Tim’s new wife Rian stepped in, ordering him a Bosch race pump and surge tank with larger diameter fuel lines for his 30th birthday. Now that’s what we call a Modified-approved marriage!
Back on the dyno “one last time” (famous last words), this time with a tank full of C16 race fuel, Tim’s Euro sports sedan killer posted a ridiculous 649 whp and 651 ft-lbs of torque. With this much power now on tap, Tim’s G now eats AMG Benzs and M-version BMWs for lunch and has Audis for dessert, but to make sure he doesn’t run into the back of these much slower sedans he also stepped up to Rotora 15-inch front and 14-inch rear big brakes, stuffed under his “favorite wheels of all-time,” a pristine set of 20-inch iForged Aeros.
With a custom front bumper designed by Viet Nguyen to house the huge front-mount intercooler properly and give Tim’s G a unique appearance, a set of ’06 G35 coupe front seats custom wired for full functionality, and a complete sound system upgrade using JL Audio components, this spotless black beauty of a four-door has got to be one of the fastest and most thoroughly modified sports sedans in Arizona—if not the country. And this isn’t some driveway poser or garage queen either; Tim takes his G-sedan to the track for both road course and dragstrip abuse, where it regularly trashes all those Euro sports sedans he dreamed of during his college years. Just goes to show, sometimes it’s best to leave things in the past, just like Tim now leaves M3s in his rearview mirror!
