Frequently Asked Questions:
Will these work in a Gen 1 B58?
The Gen 2 injectors are intended for use with the Gen 2 B58 and S58 engines only!
The Gen 2 B58, like the one found in the A90 Supra, and the S58 use a 350 bar high-pressure fuel system from the factory, whereas the Gen 1 B58 engine uses a 250 bar system.
Although the injectors look similar, the 250 bar system uses a Bosch HDEV5 injector with a 7.5mm diameter pintle shaft, while the 350 bar system uses a Bosch HDEV6 injector with a 6mm diameter pintle shaft. Although you may be able to install a 6mm stem injector into a B58 Gen 1 (a little too easily!), the Gen 2 injector will not seal in a Gen 1 engine, because of the Teflon seal stem diameter difference; and a Gen 1 injector will not physically fit into a Gen 2 engine.
