The Nissan Skyline GT-R R34 Nismo Omori Factory S1 LG7 is a car mod for Assetto Corsa that brings in the famous Japanese sports car, the R34 Skyline GT-R, fine-tuned by the Nissan's in-house tuning division, Nismo. 
The Omori Factory S1 mod incorporates Nismo's traditional tuning approach which guarantees improved performance while maintaining drivability. The S1 package features a range of upgrades including an improved ECU, better intercooler, more efficient oil cooler system, and an upgraded exhaust system made from stainless steel. 
In terms of specifications, the mod provides the R34 with a 2.6-liter twin-turbo engine that outputs around 400 horsepower, an increase from the standard version's 280 horsepower. This translates to a top speed exceeding 300 km/h, and a 0-100 km/h acceleration time in the 4-second range. 
The mod also includes handling improvements, cosmetic enhancements such as Nismo's signature red trim and decals, and an overall faithful recreation of the actual Omori Factory S1 tuned R34 Skyline, making it a must-have for Japanese tuner car enthusiasts in Assetto Corsa.
