The 4.5 Turbo
Posted: 13 Oct 2018 06:19
So every one has a page for their Patrol and I think its the right time for Wilhelm's (XenoBlitz) as well.
A couple of months back he contacted me regarding the options for turbo charging his Patrol.
At first I did not really want to get involved in this, because I only do the diesel conversions, but he was quite persistent and yes eventually before I knew it, it was standing at my place ready for the big day.
So without getting into too much detail about exactly what was done, I just want to say it was a really big job. It was my first petrol and the 4.5 needs much more surgery than a 4.8 for this conversion to work.
Things that were done:
Upgraded conrods
Top mount turbo manifold
Custom built Holsett turbo
External wastegate
Front mount intercooler with 2.5" mandrel pipes
3" stainless exhaust
Spitronics fuel management
Bosh 550 injectors
Custom fuel rail
Upgtaded fuel pump
Fuel pressure regulator
2.5" Blow off valve
Sojo Stailless air box
And more other stuff
From the start we had reliability as the 1st priority and worked around that the whole time.
We settled for 0.45 bar boost for now and will up the boost to 0.55 when it comes back after 10,000km for a service and check up. There are also some changes to be done on the external wastegate and blow off valve.
The result is 172kw and 430Nm on the 33" rear wheels
