Interesting. how difficult is it to install this? Is the Turbo itself much different than what we have stock? (referring to physical size and attachment.)

The holset he341ve is a bolt in, no adapter plates on the manifold or rear exit-stock exhaust mounts up. Depending on what kind of aircleaner is being used a new inlet duct of some type is needed in any swap, I already swapped an 85 Cali aircleaner from my first car. This turbo can give 20% more power at least, with the usual -injector nozzles-115 intake-turn up the pump a little, some guys include an intercooler 25% max which can bring the 25 plus idi 617 up to the hp of a modern dodge/mercedes sprinter electronic om602 2.5 5 cyl.
