Hey guys. I'm still pretty new here. I posted a short introduction thread for my 87 2lt Pick-up in the other forum section, but I see most of the diesel gurus hang in here mostly.
As stated in my other thread, my turbo feels and looks a bit tired. It blows lots of oil in the boost pipe and barely makes 10psi with the wastegate completely disconnected. I could simply replace it, but an upgrade sounds a little more interesting as I'd like to make the thing a little more responsive. TD04 look to be the prefered option here, but what about VNT turbos? I know controlling them is a bit different to wastegated turbos. I spent a few hours today thinking about how to use a mac valve and an Arduino to control the actuator using the truck vacuum reserve and then I found out VNT specific MBC are a thing.
Do you guys see another road block I might have missed in retrofitting a ''modern'' VNT turbo like a GT18V to a 2LT?
Thanks in advance!
