Nissan released the A31 series Cefiro sedan to Japan in September 1988. The Cefiro is a 4 door rear wheel drive sedan released by Nissan to compete with other manufacturers. The Cefiro came with an RB20, RB20 Turbo'd or with a RB25 depending on which variation and year of the car that you choose. Seeing as it was a non turbo RB25, it's engine produced, give or take a few, around 200hp which was sent to the rear wheels through a five speed manual or automatic gear box. Cefiro's can be tuned to achieve around 600 to 700 horsepower. However doing so would be unpractical as the engine finds it difficult to cope with such high levels of power so most people keep it from between 400-600 horsepower. Undeniably the engines also sound great and have a sense of uniqueness to them but this is PD where talking about so I wouldn't expect to much from them.
