For some time we are working on a big turbo conversion for the Giulia/Stelvio 2.2 JTD. Ofcourse there is the hybrid turbo option, which we are running for more than a year now. As the turbo has no problem to pump 3500 mbar of pressure, the actual power output is with ~270 hp not at the level we have seen with a GTB2060 turbo. The difficulty with the Giulia unit is that the turbine is integrated with the exhaust manifold. And this exhaust housing is very restrictive, creating backpressure that kills power. So what we need is a custom manifold where we can fit a bigger unit to. During the initial process we made designs in tubular and a more compact (log) style. The compact design was favoured because of turbo response and packaging, although it will trade a little bit topend power. The biggest challenge was to make a decent merge section for this. As we want it to have in one piece for reliability, we decided to have it 3D printed from stainless steel 316L. The printing is done with SLM technology, Selective Laser Melting which has a maximum density and very good physical properties. As it is quite a new technology for this application, we have to see in reality how it holds under full power. Stay tuned for more! ... See MoreSee Less
