Titan Motorsports introduces our cylinder head and valve train upgrade program for the Nissan GTR and it's VR38 engine platform.  The VR38 engine platform is a very robust platform to begin with, however utilizing cylinder head technology gained from our years of racing and building turbocharged engines, Titan Motorsports was able to improve the factory cylinder heads. Computer aided CNC porting allows exact dimensions to be tested and replicated across all 6 cylinder ports, achieving equal airflow for all 6 cylinders. These results can not be produced or replicated using traditional hand cylinder porting, and allow for more exact ECU tuning and additional horsepower as a result of the additional airflow.

The valvetrain was produced in partnership with industry leader Ferrea to ensure the valve and spring package would operate harmoniously with the increased airflow provided from the CNC porting. This upgraded cylinder head utilizes an upgraded OEM valve size and dual spring combination in conjunction with titanium retainers to maintain the lightest valve train possible without sacrificing durability. Reducing the valvetrain weight allows the engines redline to be raised and consistent and reliable engine revolutions in the 9000+ range to be achieved. 

The factory head flows 280CFM on the intake side and 202 CFM on the exhaust side at 28" test pressure. With our CNC port and upgraded valvetrain the result was 332 CFM on the Intake side and 242 CFM on the exhaust side at the same 28" test pressure. The complete package results in an astounding gain of 52CFM on the intake side and 40CFM on the exhaust without any sacrifice in reliability or drivability. All flow tests were completed on the latest 1020 Super Flow bench using advanced data collection which allows for a more accurate reading over the Super Flow 600 it replaces (which typically reads 10-12 CFM higher).
