Minor update, I installed more of the W140 exhaust. It won't bolt up to the existing exhaust for various reasons so first trip will be to an exhaust shop for a new downpipe. Also installed the radiator, electric puller fans, EGT sensor hoses etc. Still waiting on a heater hose, a few elbows and PCV and catch can before I can button everything up. The wastegate will be vacuum actuated so I'm working on setting up the control for that.






I drilled a hole for the EGT sensor into the EGR block off plate. The W124 and W140 exhausts are completely different so an exhaust shop will have to sort that out for me.
