Dan J is the owner of this gorgeous 2015 GT-R. The numbers are impressive: Zero to 60 mph in under three seconds; a top speed of 196 mph; 545 horsepower courtesy of a hand-built 3.8-liter twin-turbocharged V6 assembled in a clean room so high-tech that those fleeing scientists on the silver screen would kill to have one. This beast has also been finished in premium Regal Red paint embedded with 24-karat gold flakes! We think it is mesmerizing under varying light conditions:

Combined with an Ivory interior this R35 exudes a level of refinement and luxury not typically seen on earlier models:

Sidenote: I met Dan in December ’14 while helping his neighbor with a Datsun Roadster. Dan kindly let me park the 510 next his GT-R and I might have mentioned how we love them at ZCG 🙂

So what does one do with such a beautiful sportscar? Add more power, of course! Dan came to us for a full AMS Alpha 7 package installation.

The package includes:

• ALPHA front mount intercooler
• COBB big SF intake pipe
• Alpha 90mm Mid-pipe
• Alpha 90mm Downpipes
• HKS Legamax Exhaust System
• Injector Dynamics 1000CC Injectors
• Cobb AccessPORT V3

Let’s start with the exhaust and a closer look at the new mid-pipes and down pipes:

OEM vs Alpha downpipes:

Mid-pipe:

Completing the system is the HKS Legamax exhaust. Fresh from the box, compared to the OEM system:

Great, OEM-like fit with factory underbody Aero:

Looks fantastic here and sounds even better!

Underhood, better breathing is achieved through larger intakes and K&N air filters. Stealth black tubing is nice touch:

Rounding out intake mods is a larger Alpha front mount intercooler. It boasts 75% more internal flow area over stock and direct bolt-in/no cutting fitment! It doesn’t hurt to have the “Alpha” logo peeking through the front bumper too:

Fueling demands are met by larger 1000cc injectors:

How do all these mods add up to increase power? To find out we strapped the red beauty to the dyno:

Utilizing the CobbAccessPORT V3 for tuning we saw peak gains of 80hp/86tq for a total of 577hp/562tq to the wheels. The dyno plot reveals tremendous gains from 2500rpm to redline. For example at 4000rpm the GT-R is now making 560tq vs 460tq stock!

Dan’s GT-R was already blindingly quick from the factory and now it has even more power to enjoy while maintaining its Regal composure. Thank you for bringing your R35 to Z Car Garage! More pictures to enjoy in the gallery below.

For folks that live in the US, it’s hard to imagine a bigger piece of forbidden automotive fruit than the Nissan Skyline.  The Skyline has never been sold in the United States, yet it’s still managed to develop a fanbase and aura that can easily rival the best foreign or domestic metal. Most of us are familiar with classic Skylines and modern GT-Rs, but the DR30 you see above is still relatively unknown among non-JDM lovers. Reid B. scored this lovely red Skyline 2000 RS-Turbo almost four years ago.

The pillarless windows,  angular body shape and killer graphics package create an unmistakable 80’s vibe. We love it!

Soon after Reid purchased the DR he started making it his own while preserving the classic OEM goodness. He brought the car to us initially for a dyno and tune after noting that the Skyline had a flat spot in mid-range power delivery. When we inspected the car we found the front suspension was severely rubbing on the tires and this was addressed first.   We installed Techno Toy Tuning (T3) coil-overs with custom springs, RCA’s, Energy Suspension T/C rod bushings and AGX shocks:

Although Reid was hoping to fit a 215-width tire up front the DR now sports 225/50/16 Yokohama S-Drive tires at all four corners with great clearance. Watanabe wheels look so right on these!

This being a 1983 model, it sports Nissan’s legendary FJ20ET powerplant underhood. Reid was concerned about potential fuel delivery problems and our A/F monitoring revealed lean conditions under load. We discovered a failed fuel-pressure regulator and our solution was to replace and modify a 280zx fuel pump and FPR to fit.  A new oxygen sensor was also installed.

Further inspection revealed over-boosting so we lowered the base boost rate with a lower pressure spring in the external wastegate. Dyno results were great and we’re happy to report the DR makes more power at less boost now! Baseline numbers were 160hp/177tq and after 201hp/197tq to the wheels:

We liked working with Reid as he is the type of owner that wants to bring the car back to life the best he can. Z Car Garage lives for reviving Japanese classics and hearing our customers satisfied with their cars keeps us going. Listen to Reid’s impressions after picking the DR30 up:

Rob,

So the drive home was awesome. I still cant believe it. I didn’t get to drive it to work today but tomorrow for sure. I could drive 80 and then roll on the gas and it would just go and not want to stop. The new front suspension makes the car drive so much better, it doesn’t feel like it rides on cut springs.  I drove the car from Newark to Roseville and it was awesome going from 75-95. I could roll on the gas it would start boost and just keep going. I feel like when I am driving now that I am holding the car back cause it just wants to go and go.  I am still in awe. 

Reid

Enjoy The Ride, Reid and thank you for giving us the pleasure of working on your Skyline!
