The heart of the NISMO R33 GT-R 400R is the RB-X GT2 engine.
Using accumulated results from countless races, with the data being applied for a thorough review and modification, to provide specs focused on increasing engine displacement and the resulting increase of torque and low- and mid-speeds. The result is smooth acceleration and a swift run-up from low and mid to high speed: a special “400R-ness” that makes this completely different from other 400-horsepower class tuning cars. |
