Awaiting to pounce, the HGMS GTR early awaits to gobble up fuel and lay down rubber on the track.

So unless you’ve been living under a rock in SoCal, most know of Dieter and and his team over at HG Motorsports, a Southern California performance shop that focuses on performance builds, and one of the few places that actually has the aptitude to work on your priceless exotic. The team at HG focuses on getting the job done right and with the highest quality of parts available. The one thing that I found interesting when I took my car there last year for the WRX alignment, was that they work on all sorts of cars, including your normal every day daily! HG catered to my every need when I took the car there, answered every question, even helped put together a build sheet for some ideas I had. I was quite impressed with their demeanor to “just an autocrosser”, and would recommend anyone that’s in the San Diego area to check them out. So when Dieter started posting some stuff about this ‘wicked GTR’, I knew that it had to go on the site as a featured import. So fellow Junkies, as long as the wait has been, here’s the Featured Import for August 2016: The HGMS TrackSpec GTR.

What type of car do you have?

2009 Nissan GTR

A lot of people give their cars nicknames/actual names. Do you have one for the GTR?


How much power is the car making to the wheels?

Despite the car not being dialed in WickedGTR and the team at HG manages to get top time in class!

Despite the car not being fully dialed in, WickedGTR and the HG Team manages to get regular top times in class!

650hp to the wheels.

Mod List! Let’s have it!

  • HGMS 700FF Power Package (injectors, fuel pumps, flex fuel kit)
  • Stage II Transmission Build
  • Brembo GT-R Motorsport front brakes with HG Cooling ducts
  • JRZ Pro 4-way adjustable dampers with external reservoirs
  • APR Performance Aero Package (splitter, canards, and wing)
  • HG Harness bar with Sabelt seat / Takata harness
  • HRE 18″ Wheels & Pirelli P-Zero full slicks
  • SSP Trans cooler and HKS Trans cooler
  • Full Whiteline suspension kit
  • Delicious Tuning Dyno Tuned

As clearly a track-centric build is there a lot of adjustment that needs to be done to tailor the GTR to each track? Is there ever a time where the power is dialed down to handle the varying conditions?

Not really. there are some minor changes we make but this car is pretty stable and balanced to deal with each track.

What was the biggest “surprise” or obstacle you faced when you worked on the car (as in what was maybe supposed to have been an easy task but ended up being a pretty huge undertaking)?

Honestly everything on this car seemed be difficult. The real problem is the weight: at 3950lbs with the driver and with the speeds this car creates, physics comes into play. At 100+mph getting that much weight to change direction is interesting, but we have been able to make it work. thanks to virtually the endless adjustability of the various components used in this build.

What is the one of the most important reliability mods that was done to the  GTR that all GTR Owners that track their cars should look into doing?

Primarily this the transmission should be beefed up. As with most turbo cars, cooling and servicing. It’s interesting: most people that buy GTR’s do not understand how crazy the car actually is and what it is capable of. Godzilla is hungry and will eat everything in its path but therefore it needs to be taken care of. It’s a simple philosophy: take care of the car and it will take care of you.

What kind of data-logging system do you use?

We are currently looking into data now … either Motec or AiM will be our choice it sounds like.

Let’s talk suspension. Given the geometry what do you think is one thing the car could do better (i.e. sweepers, hairpins, transients)?

Definitely Sweepers. We are still getting a bit of front-end push (understeer) due to the weight, even with the nice big tire. We are working through a few other topics on the car but front bite has always been a problem even with the aero.

Given the supporting motor upgrades, has it been fairly reliable given the severe punishment it goes through?

Thankfully the VR38DETT engines in the Nissan GTR’s are SUPER strong and take a beating as long as you service it and keep the torque rating low down low they will last just fine. The transmission had many problems before we were involved, but now with the right parts and service the WickedGTR has been able to make it last over 8 track weekends and is still going strong!

Are there any sponsors/partners you would like to acknowledge for their assistance in getting your car to the way that it is?

HRE Wheels - not just for show...these wheels see regular track duty no super grippy Pirelli full slicks.

We here at HG don’t really believe in Sponsors … We have partners – they seem to work better: JRZ Suspension, Brembo, Motul Fluids, Mothers Polish, APR Aero, Delicious Tuning, and HRE Wheels helped us bring the car to where it is.

As most of raced cars undergo continuous changes, what are the next plans for the car?

This has been a three-year project of various setup changes to make this car work at the level we demand. As of right now our next focus is aero (aero in the chassis sense – not part of the body sense) as that is the biggest factor to help or hinder a car. We are looking at ways to allow air to flow through the car better and not around.
