I am about to start the inspection/overhaul of my EA82T. This engine will see continuous operation at 4400 rpm and periods of 4700 rpm (15-20 minutes). It will have a TDO4, intercooler, oil cooler, and run synthetic oil. My first question is if the stock crankshaft for this engine is nitrided? Would this be a good idea? Could I use the stock internals, primarilly rods and pistons for this kind of setup? I prefer to keep everything as stock as possible, but if it needs to be changed for good reason it will be. Any comments would be welcome.
Thanks in advance,
Subpilot

4700 isn't a lot for these engines. Part of me says don't worry about the bottom end.
The other part of me suggests shot-peening the rods, and upgrading or at least replacing the rod bolts.
Synthetic oil wouldn't be a bad idea. Keeping an eye on oil temp wouldn't be bad, either. An oil cooler might be a good idea.
Nah, screw all that. 4700 is nothing for thee engines.

Well, if you plan on being at high levels of boost for an extended time, then I would look seriously at oil cooling and maybe egt. the stock bottom end is still very rugged.

I would be more concerned about the top-end than the bottom-end. You should seriously consider going to better engine-management elctronics.
