Expiremental OM617 build
i got the turbine housing discharge flange made by a local shop for me. its got a minimal amount of material blocking the exhaust flow and a 3" v-band outlet. kind of ridiculous but every bit less of restriction post turbo helps.[img]<a href=[/img]" />
i also ceramic coated the exhaust manifold. mind you its not a high quality coating but everything helps, and i dont intend on keeping the EGR manifold for long. looking into using a W115 N/A exhaust manifold to feed a twin scroll housing on the HE221W (TD04HL housings fit the hot side of the 221 and there is a 8.5CM twin entry housing for them.)[img]<a href=[/img]" />
it kind of amazes me that the HE221W can flow as much air as it can upwards of 36LBS/m.

in other news i am in the process of getting a quote from Pauter for a custom set of connecting rods. not going to need them any time soon but i just wanted to know how much it would be. they make a rod that is almost exactly the same as the 617 but the small end is ~1mm too small. Its for another Mercedes but i cant remember what off the top of my head right now. ill keep posting as more progress and pictures come.
