Can I swap a disco 200tdi timing chest for a defender one? Or not bother?
First 90 but 2.5 na is dead, got a disco 200tdi to fit, so hopefully all goes well
No need to bother. Loads of N/A to 200tdi info on here and elsewhere. In particular, have a look at the Glencoyne engineering website. Any questions (after you do a search) pop into the defender forum and ask.
