Infiniti I30-I35 engines
The Infiniti I30 sedan, created specifically for the American market in 1995, was a copy of the Nissan Cefiro/Maxima model and differed from it only in its external decor, which was supposed to give the car more solidity. The car was produced in Japan, and its sales were also carried out in some Asian countries.
The Infiniti I30, which had front-wheel drive, was equipped with a 3-liter V6 engine producing 190 hp paired with a five-speed manual transmission or a four-speed automatic. The lineup also included a “sports” modification, the I30t, with a retuned suspension and body kit.
In 2000, production of second-generation cars began in Japan. The Infiniti I30 was still virtually identical to the Maxima/Cefiro in both design and construction. Under the hood of the sedan there was a modernized V6 3.0 engine, the power of which increased to 227 hp. American buyers were offered only cars with automatic transmissions; manual transmissions were retained on versions for the Middle East.
The modernization of the model, carried out in 2001, affected the appearance, interior, and settings of the vehicle’s chassis. The list of additional equipment has been expanded, in particular, a stabilization system has appeared. But most importantly, the sedan received a new V6 3.5 engine with a power of 255 hp and was renamed Infiniti I35.
The production of cars continued until 2004.
The Infiniti I30-I35 was offered with 2 engines between 1995 and 2001 (2 petrol). Displacement ranges from 3.0 to 3.5 liters, power output from 190 to 305 hp. All of them use a timing chain. The longest rated lifespan belongs to the Nissan VQ35DE (about 400,000 km).
