Hi guys, for anybody looking to squeeze some extra power out of their 320D or any of the turbo charged diesels, it's not as expensive as you might think. I know of a company who will build cores with any compressor wheel you specify and machine out your compressor housing to suit. Put it this way, I bought a new core £139, Had my compressor housing machined out £125 and delivery £9.95, that's it! and its not as if it's not a good quality unit either. It comes fitted with an upgraded 360 degree thrust bearing and step gap oil sealing rings and a full 12 month warranty. May be a little more expensive if you have a different model to mine!
Mine started out life as a GT1749V and now it is a GT1756 so +7mm on the compressor wheel and should be capable of 230bhp+ with a few other tasty mods. You can see in the pics that the new compressor wheel is also a lot taller as well as wider
Big step down from £500 for a recon hybrid or £1180 for a complete new hybrid unit.
