Mercedes Benz E250 Turbo Install - Part 2

So finally the plumbing for the turbo install was completed with most of it being basic routing and cutting and welding the stainless steel pipe to feed the intake manifold from the turbo.
The only major work or modification that was done was the closing of crankcase breather inlets which were earlier used to feed the crankcase blow by air and oil fumes into the intake manifolds 10 different points. These were closed by machining small metal bungs which were press fitted into the openings with araldite adhesive.
These reason these have to be closed is because after a turbo is installed , the pressure inside the manifold is no longer negative or vaccum type. It is now under a positive pressure change since the turbo is constantly pushing in fresh air into the manifold and this pressure is going to make the rubber pipes from crankcase breather pop off under pressure.
The crankcase breather is then routed out into the atmosphere through a k&n breather filter.
This is the first of the 3 different turbo options that we have at hand available. Garret, holset and Borg Warner.
Will be logging boost data once pump work is complete.
Looking at making a healthy 22+ psi boost for a nice long powerband.
So we have the option of not only trying different turbos but also can play with the number of fins/vanes on the holt or cold end as per requirement.
Will be a trial and error till we land with something that feels the most drivable.
That can only be decided once the pump is upgraded as currently it is running very lean.
Post turbo install the engine sounds really mean and ready to lift off. Revs very freely and definitely doesn’t feel like a diesel at all.
No wonder these are called the diesel 2jz.
Will soon share details of the pump upgrade as well.
