Umm, news flash.. those kind of cars that he races have their engine rebuilt before 50k miles.. =P It has nothing to do with the PSI being put into the engine. The PSI being put into the engine will add wear and tear to the engine, not the turbine. The wear and tear of the turbine is the berrings from being spun up all of the time. And if anything, there is more wear and tear on a street driven turbo then a track turbo because in street driving you are constantly spinning it up and down as you are switching gears where as the turbo in a track car is staying around a consistant RPM.

The point is berrings get worn out in turbo's, as well as the seals, and they begin to leak oil into the intake of the engine, thus causing damage to the engine. I mean seriously, how often does it come around that you put 50k miles on your car? So in the lifetime that you actually own your car, you'll have to rebuild it maybe twice? And you only put an average of what, 15k miles on it per year? maybe 20k? So you'll only have to rebuild it once every 3 years or so. That's not really bad... Being that the average person drives a car for less then 100k miles before they get rid of it. If you drive your car to 300k miles, then you are not the average person, however if you are going for performance and souping up your engine for performance, you also shouldn't expect to get 300k miles out of your engine. A turbo puts a lot of additional strain on the engine, so I wouldn't expect it to last 300k miles with a turbo on it =P

I am familiar with the basic procedures most turbo cars go though when they go in for 30k service, 60k service, 90k, etc. The basic services do NOT include rebulding a turbo. I know guys with 1st gen DSM's that have 150k+ miles on their cars and the same turbo from day one, with no problems.

It costs a lot of money to rebuild a turbo. Not so much for parts, but for labor as well. Manufacturers would not put turbos on cars if they cause severe damage to the engine after only 50,000 miles. It would not only cost them thousands of dollars in engine rebuilds due to people not knowing when their turbo is actually leaking oil, but it would also cost them a fortune in parts and labor time to repair and rebuild the turbo. And all of this would fall on them due to the fact that most any turbo car priced under $35,000 has at least a 60,000 mile powertrian warranty.

A stock turbo does not put a lot of additional strain on an engine. Cars stocked with turbos from the factory have engines that are built to last with their stock system, just the same as any NA car.

If it specifies in the required maintenance manual however that you have to replace the berrings and such every 50k miles and the person doesn't do so, and their engine dies, the engine would not be covered under warranty because you didn't fulfill your part of the warranty requirements. Regardless, maybe you are right. I'm going off of knowledge of others rather than my own personal knowledge, so if you say it's otherwise, then maybe it is. I just took his word for it because I know he knows his way around a car =) He was even telling me that if I got a turbo for my car I too would have to rebuild it every 50k miles or so... so dunno.. =P

Show me where any service manual says that.

i know that Rulez has a turbo on his car, so he would know more about puttin a turbo on an eclipse than most people. u could also look into the supercharger by RIPP for our cars. ive heard they r pretty reliable and can give about the same amount of whp. just another option.

[Rulez]

The RIPP kit is an aweosme kit for sure, but the 4cyl is just so easy to turbo, I'd prefer that.

Superchargers have a real linear power curve because they only hit full boost at redline, whereas a turbo can hit full boost at midrange, depending on what turbo you have. Therefore, a turbo's powerband is more favorable.
