Amuse GT-R Nets Over 600 Horsepower!


Amuse is a Japanese tuning company that has a long relationship with Nissan’s R-Series. They eeked every horsepower they could from the old RB26DETT engine, harnessing over 1,000 horsepower on the brawniest of Skylines. But with the recent release of the GT-R, most aftermarket tuners are turning their eyes away from the old R32/33/34 to focus on the fresh meat.

Amuse is one of the first tuners in the world to be able to successfully play with the GT-R’s ECU and win… and win they did.  So what exactly did they do to get 602hp at 6,500rpm and 571lb-ft of torque at 5,300rpm from the already highly-tuned GT-R? 

Well for starters, they up’d the boost.  A lot.  They also added a full titanium exhaust, electronic boost controller, and they removed that pesky 112mph speed limiter.  But the real trick was making the ECU work correctly with all these changes… GT-R ECU’s haven’t liked it when tuners did so much as change the wheels and tires, so you can understand that this alone was a monsterous feat. 

To make it lighter on it’s feet, the titanium exhaust and all new Recaro carbon-Kevlar racing seats dropped 100 pounds off the curb weight.  Add in a removable MOMO steering wheel and you’ve got the meanest GT-R in the world (so far). 

Dubbed the Power House Amuse Phantom GT-R, you’ll be able to buy these auto parts from Amuse sometime in 2009.  Until then, your stock 480+ horsepower GT-R will have to suffice.
