How to get 200K miles out of an EVO?
Stock turbo on E85- 24/25psi most likely. I think it has far more to do with how much you rip on it than what boost. If I ran my car continuously at 16psi for 13,000 miles I think its far more likely to fail than 29 once or twice a week. Obviously thats deliberate exaggeration but I think in the end thats what it boils down to.

I was seated in a barber chair one day eavesdropping on the conversation going on at the next chair. The customer was an insurance agent and he and the barber were talking about car insurance. The insurance agent said to the barber that a specific car that was then popular with young people had a life expectancy of less than 18,000 miles.
Nowadays a typical family car has a life expectancy of about 150,000 miles but can go much further if taken care of. But the Evo is a young peoples car. So, if I could get hold of insurance records for the Evo I'd expect to find that the life expectancy of this car is shorter than average due to the car's racing heritage, that fact that some are actually used for racing and the age of the drivers.
Beating this average is going to depend on luck, where you drive and how good of driver you are because wrecking your machine is how not to make it to 200K. A blown engine can be repaired.

I voted 20 psi, that is close to the factory boost level where the engine was designed to run. Add to that a free flowing intake/exhaust and it will take some level of wear away from the engine rather than adding it.
Stellar performance is reached at higher boost levels but you are asking for longevity in the way of 200,000+ miles and that is not going to be reached with high boost levels.
Oil type/filter type, regular oil changes and a timing belt/water pump every 60,000 miles is also good insurance.
Quick story, my mother bought an AWD Talon in 1993. She brought it to me the day after buying it and said she wanted it to run 12's. I told her put 1,000 miles on it and come back. She did that. We put a 2.5" turbo back on it, K&N filter, modified the air box, upper i/c pipe, did some port work to the turbo components, manual boost controller set at 18-20 psi and a fuel pump. She drove that car for 165,000 miles, trouble free. She sold it to a local guy here who drove it until it had 190,xxx miles on it, trouble free, he wrecked it.
The car was taken very good care of with routine maintanence done like it was suppose to be, that is the key.

with reasonable maintenance, these engines will last nearly forever. Here's some pics at 250k from my AWD DSM- bearing and crank still looks new. This car is stock, probably the last stock one left, so I'm sure that helped some. I had the oil pan off to reseal it and figured I'd check a bearing. I was shocked it looked so good. This is on 3500-4000 mile oil changes- conventional oil, fram oil filters until ~160k and then purolator filters

Please vote. Not as interesting as health care I admit, but I would like some more voteage.
Thanks,
