I'm about to start a rehab project entailing my 84 300SD and would like to go a certain route yet still be a daily driver. First off, The car has 316K on the odometer with the chain, guides, seals, and so on done by the previous owner as well as the driveshaft rubber discs. I just replaced the finger valves, transmission filter service, oil service and removed the air filter and installed a freeflow unit. She still is dog slow but I deal with it because this is my first diesel. Anyway.....
I want to do performance upgades along the line of:
- slightly bigger turbo with internal WG. Could the spring be replaced or the Internal WG be replaced for a stiffer unit to hold higher pressure?
- 2.75" exhaust pipe exiting right after the front wheel under the P/S door.
What do you guys recommend? I don't really care about noise as she'd be my ratrod style daily along with her new paint, suspension, and wheels....
Thanks,
