Is your Ford Transit Custom MK8 (with the 2.0L EcoBlue diesel) losing power or smoking? The turbo might need a rebuild. This is a brand new turbocharger cartridge – that's the core rotating assembly (shaft, compressor wheel, turbine wheel, bearings) that you swap into your existing turbo housing. Part numbers 838417 and 838452 from TPUK. Fits both FWD and RWD models. A cartridge replacement is way cheaper than a whole new turbo. You'll need some mechanical skill to disassemble your turbo and install this, but it's a solid DIY job for a skilled mechanic. Comes with a 1-year warranty. Breathe new life into your work van's performance. Fix turbo lag, whistle, or oil consumption. Get your Transit back to pulling strong and delivering full fuel efficiency. A professional-grade part for a common repair.
