Employee Build: Alex’s 2003.5 Turbocharged Infiniti G35 Drift Sedan (Part 1)

Employee/Author: Alex Docken

Position: Supply Chain Manager/Accounts Payable

Editor: Art Petrakov

First of all, I apologize that my initial GrimmSpeed blog feature isn’t that of a Subaru, but I have had several throughout the years, including two SF5 Foresters, and most recently a 2004 STI. In fact, the Foresters are what sparked my interest in working at GrimmSpeed in the first place. With that being said, the following is a short introduction to my current 2003.5 Turbocharged Infiniti G35 Sedan build.

I bought the car back in 2013 from its original owner. It’s a clean Colorado chassis with a rare combination of no sunroof, 6 speed manual transmission, and black leather interior with none of the heavy factory upgrades such as Bose or navigation. I have built the car in multiple stages over the past several years, but here you see it in its most current configuration:

The G currently produces 517hp/520tq using e85 on a Dyno Dynamics dyno. It was tuned by Shane at DB Performance in Rogers, Minnesota using a Haltech Platinum ECU. The car is built specifically for drifting and has all the typical mods you would expect from a purpose-built drift car. Here is a [mostly] complete list of upgrades:

Suspension:

  • Parts Shop Max (PBM) Front Lower Control Arms
  • PBM Rear Traction/Toe/Camber Arms
  • Pro Coilovers with Swift Springs
  • SPL Solid Subframe and Diff. Bushings
  • SPL Sway Bar End Links
  • Hotchkis Front and Rear Swaybars

Brakes:

  • Chasebays BBE/Prop Valve Kit
  • Custom brake lines made by Rad Industries
  • Maverick Dual Rear Caliper Brackets
  • PBM Hydro Handle with Wilwood Master Cylinder

Transmission:

  • Stock 6-speed Manual
  • Z1 SS Clutch Line/Solid Trans Mount/Chromoly Pivot Ball
  • Spec TwinDisk Clutch – Street Trim

Engine:

The power-plant of the car was built by Landon Haley of Landslide Performance. The engine is packed with Cosworth Bearings, Manley “Turbo Tuff” I-Beam Rods with Manley Platinum Pistons, and ARP Rod Bolts and Mains. The block itself was modified by Landon to accept Nissan’s updated HR series headgaskets found in the newer, more powerful generation of VQ35 motor. The head bolts and oil pump were upgraded to HR spec accordingly. It has a JimWolfTech twin turbo kit utilizing a pair of their upgraded 700bb series turbos. The charge piping and custom V-mount Intercooler setup were done using Vibrant Fabrication components, a Turbosmart Raceport Blow Off Valve, Treadstone Intercooler, and a C&R Dual Pass Nascar Radiator. All of the custom front-end fabrication was done by local Ryan Clemens of Oppomoto. The bay is kept clean and functional thanks to the good people at ChaseBays. The car is fully equipped throughout with their reservoirs including their newly updated ChaseBays Dual-Baffled Power Steering Reservoir.

Fuel System:

  • Walbro 450 Pump
  • Radium Engineering Surge Tank
  • Dual Walbro 450lph e85 Fuel Pumps
  • Cosworth Fuel Rails with ID1000 Injectors
  • Aeromotive FPR

Exterior/Bodywork:

Nathan Chin of Metal in Motion brought my visions to life with the custom vented hood, vented/widened front fenders, and the modified Outcast Garage Front Bumper as well as the extensively modified 326 Power Spoiler. The bottom portion of the car is equipped with Outcast Garage Side Skirts and Skirt Extensions along with a Varis Rear Diffuser and Canards. There are countless other custom changes, upgrades, and fabrication that have taken place with this car over the past year, many of which I will showcase in future blog posts.

This car is always an absolute work-in-progress for me, and I have several big changes planned for this year. I am constantly trying to find ways to make the G more exciting, since that’s my overall goal with this build. The car is currently undergoing some visual changes by Nathan who I have trusted to do my paint/custom body work and will continue to do so until the car is exactly where I want it. Along with the new body work, you’ll also see me sporting custom livery for my Drift team “No-Mind” (check us out @no_mind_drift).

In addition to changes with the car, there are some exciting new events coming up for me this season. The car will have its 2017 debut at Wekfest Chicago April 30th, then off to MI Drift at Gingerman, Gridlife Midwest, and of course my favorite, the ClubFR events in Shawano, Wisconsin. Overall I’m looking forward to quite a great season this year!

I hope you stay tuned and look forward to upcoming exclusive content such as installs and sneak peeks at this season’s debut. For more photos, videos and details follow me on Instagram @DabSedan
