Hello guys,
I'm new here so I will introduce myself a bit first. I’m a 20 years old student car technologies, next year in my final year of high school I need to do a thesis project. The project that we will do is a dual parallel vnt setup on a 4.2 straight six Nissan patrol engine. The idea is to put a turbo on the first 3 and one on the last 3 cylinders. By that way we create 2 times a displacement of 2.1 liter for each turbo.
Because I know that the VAG group use a lot of vnt turbo’s I registrate here on the forum cause you guys can maybe help me in choosing the right turbo? The idea is to get a flat torque map, ideal would be to get the turbo’s spooling at around 1500rmp until the engine reach 3500rpm so on pretty low rmp’s. I was thinking to use the gtb1749vk that is used on the 4.2TDI VAG engine, that because it has the same displacement as my engine and I can find it pretty easy cause it is used by Mercedes and ford on their 2.2 liter engines. I have read a bit here on the forum and saw that many people use the gtb1756vk on 1.9TDI engines and get the turbo spooling at 1800rpm? So I’m now doubt of what I will do? Can you guys maybe give your ideas of what I can do best? The ideal for me is to get 14psi from 1500 till 3500 rpm and maximum 20psi that the turbo can deliver.
We want also work with electronic actuators, we work with IFM electronic module to write a program that generates a pwm signal to let the actuator react.
Thanks a lot guys!
