Install a good block heater that can keep the engine block at a temperature between 80 and 120 degrees F. 2. Install an oil heater "". 3. Install an electric oil pump that can provide 20 to 60 PSI of pressure. (this should switch on 30 seconds or so before the engine is started.) (You should be running synthetic oil right?) 4. Install several oversize oil filters so you don't have too much back pressure at the filter. 5. Install a coolant pump that can keep the coolant circulating at about 5 to 10 psi. (this should switch on 10 seconds or so before the engine is started.) 6. Install a battery bank to power your startup pumps. (You should already have this for your starter unless you have an inertial starter. If you have an inertial starter, you should probably have batteries for the flywheel moter to spin the flywheel up in a no power situation.) 7. Inspect your glo-plugs after every run cycle. Clean or change if needed. 8. If you begin a run cycle, run under load for no less than 4 hours. 9. Perform monthly run cycle tests. 10. Check your batteries often. Keep in mind that those people who claim their gas turbine has faster switch-over time and never misses a start are probably running their compressors all the time at 100% RPM and applying fuel and turning on the igniters when they have a failure. Switch-over time is pretty damn fast in those cases. (under a second or two in most cases.) Anyhow, thats all the ideas I've got off the top of my head... (One of my long range projects is to build a small generator complex for my future house. Primaries run off of natural gas and the secondaries run off of diesel. I'm planning on using Nissan inline 4s as they're easy to work with and fairly cheap. I figure I can get at least 15kva out of a pair. (I've only got 10kva of UPS to feed so this shold be fine.) Should be fun.) /* Matthew N.
