![]() ![]() The actual head components are the same (Well at least interchangeable with non vvti and aftermarket parts). The exhaust cam/cam gear is the same as the non-vvti exhaust cam and can take aftermarket cams such as HKS, JUN etc. Yes and no! The vvti has a different Intake cam/cam gear (As it’s VVTi!) Aftermarket cams are available for the VVTi such as HKS’s Valcon system yet they are expensive, a custom grind is probably a more viable option. Some further reading and explanation of VVTi with diagrams: Īre VVTi head components different then non-vvti? Unlike some systems that switch between two compromise settings,VVT-i adjust continuously,tailoring performance to suit virtually any situation. The result is exceptional low-end torque to get you off the line ,mid–rang punch for passing situations and clean-burning efficiency throughout the rev range. Variable valve timing with inelligence(VVT-i)optimizes engine efficency by constantly retarding or advancing intake valve timing depends on conditions and engine speeds. How the ETCS-i (throttle control system) works ECU is OBDII based using JOBD specification/protocol (ISO 14230) but you cannot use the standard OBDII scanners to read error codes/diagnostics etc It still has a OBDII connector and can be scanned using a scanning tool and software, you can read more about this here –.Fly by wire throttle (Still has throttle cable).Airflow Sensor: Hot wire type airflow meter.Stock recommended NGK plugs: BKR6EKPB11.Stock recommended Denso plugs: PK20TR11.The VVTi 2jzgte came in JZA80 Supra from September 1997 – July 2002.(VVTi 2JZGTE left – Japan Only, VVTi 2JZGE Right – US/UK Only – This is true for supras, other toyotas may have had these engines available in other models) ![]()
