What parts are the same as non-vvti? (Confirmed from EPC and personal experience and research) The only 1 different part number I found was the crank pulley (not the whole dampner/balancer, just the pulley, look like exactly the same thing, and they are!)
Below I have listed all the parts and they are exactly the same, they have been confirmed in the EPC (Toyota Electronic Parts Catalog) Pics are also shown below in the end of the post. Also the crank is exactly the same and so are the pistons and everything else in the bottom end. The VVTi 2JZGTE rods are the exact same size as the non-vvti units. No, some Toyota lovers will know that most of the later model vvti engines such as (1UZ, 3UZ etc) had weaker rods. The only difference I found in part numbers were the shims, not sure on differences, may only be part updating and no physical change. 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)
