cool build man, gonna watch thsi progress
heres the quote from wiki on the nismo edition
"The Skyline GT-R 'Nismo', introduced in February 22, 1990, has a total production of 560 units as required for the "Evolution" models regulation (over 500). Its purpose is to homologate a number of aerodynamic changes used in Group A racing. Changes include additional ducts in the front bumper to improve airflow to the intercooler, a bonnet lip spoiler to direct more air into the engine bay, and an additional boot lip spoiler to provide more downforce. The 'Nismo' GT-R was only available in Gunmetal Grey."
