I forgot to mention that the 16G has been in my eclipse since it had 541 miles...I just checked my little book today...and now its got 90,461 miles..... I would be suprised if you dont get 70k out of your motor with proper care.

 

my teg had 150k miles and still raced like a ****. hehe.. talk about honda reliability.

 

Bump for the cams question and higher mileage owners...

 

Most common causes that will shorten engine life:

1. Ignorant driver - one wrong shift and the engine will overrev tremendously due to the short gearing.

2. Improper maintenance - failing to change oil and performing other factory recommended service.

3. Inadequate warm-up - driving too agressively before the engine has a chance to come to operating temperature will damage the motor. The best way is to start up the motor, then immediate drive but with a very light throttle to help the engine come up to temperature more quickly than idling alone.

4. Inadequate cool-down - good way to fry the turbo. Get a turbo timer or don't drive too aggressively for the last few minutes of the trip.

If you try to avoid all of the above, you should have no problem with your engine.

Good luck!

 

Mods that will kill your motor:

1. Improper boost control - you can't just slap on a boost controller and haphazardly crank up the boost. Increased boost must be accompanied by increased fuel supply and increased intercooling capacity, and possibly timing retardation to prevent predetonation. If you're running really high boost, the block may need to be reinforced.

2. Improper use of nitrous oxide (NOS) - same with boost. You can't just slap it on. You have to tune the car to use it.

3. Mismatched ECU programming - you have to tune the ECU to all the parts that are on the car. If not, the engine will suffer as the ECU struggles to compensate. Different parts operate at different ranges. The ECU doesn't know how to compensate the parameters, and you may end up running extremely rich or extremely lean.

When you think about it, there are actually only a few numbers of mods that will decrease engine life. The general rule of thumb is that as power increases, reliability decreases. It depends on how much you're willing to compromise.

Tuning also goes a long way. If you tune your car just right, you can put down 400 bhp and still have a reliable daily driver.

 

if im not mistaken, intake/exhaust wont harm the engine life since if you think about it logically (w/o getting all techy n stuff)...you're basically letting engine "breathe" better right? you're not really forcing the engine to work hard (like turbos or other forced inductions), thus not really harming the engine...however, things like bigger turbo, cams, MBC (aka higher boost), etc are probably gonna shorten the life since you're basically forcing the engine to burn more gas, thus forcing it to "work harder." of course, i could be wrong, but ive heard these things from a seasoned mechanic so thats why im planning to only get intake, exhaust, and ecu so that i wont really shorten the life span of the engine (since i wanna keep my baby as long as i can)...there are some things you can do to help the engine last long like frequent oil changes, non-aggressive driving, adequate cooling (turbo timer isnt a bad idea), etc etc etc.


well to cap this off, just remember..."the car will treat you the way you treat your car"

 

in a nutshell: ie. a stage 1 kit would only increase efficiency of the vehicle (better breathing as you stated being one of the positive outcomes). don't NOS, drive like a dumbass, or boost 35psi and you'll be fine.

 

The most common cause of premature engine failure is predetonation. The gasoline mixture in the engine needs to burn at the right moment to drive the piston down and generate engine power.

The piston needs to move up and compress the gas so that the engine will get a good burn. It's like burning gun powder outside versus compressing it into a bullet and burning it. You have to compress it to generate the force of the expanding gas and do useful work.

Sometimes, the fuel mixture will get burn during the compression stroke. Imagine the gases expanding as you're trying to compress it. It's going to put a lot of pressure on the piston, connection rod, crankshaft, etc. This makes your engine go boom!

So if you fool with fuel mixture, or if you fool with cam timing, you may set off predetonation.

You would have to be hard pressed to damage the motor with just an intake and exhaust. The increased intake capability doesn't mean much because the computer can meter the incoming air, and can compensate for the additional flow rate. So as long as you filter the incoming air somehow, it should be okay.

Same for the exhaust. You may lose some low end torque with a free flowing exhaust, but for the most part it will not cause predetonation.

 

HIGH LIFT CAMS will, not higher duration such as HKS cams...

 

i dont think its the MODS that "will shorten engine life" - I think its the driver and owner of the vehicle. Maintainence of the highest quality with the best products by a qualified person is necessary. Driving the vehicle properly with added mods is also necessary. Installation and proper tuning I would also suggest with mods. Check up on your car every so often, its easy! Good luck.

 

Lots of folks mentioning smart use of Nitrous ... hmm, lots of posts around that seem to indicate that that nitrous and the evo engine don't work well together and end in rather debilitating failures in a very short period of time.

(1) do your maintenance
(2) keep the stock intake (Vishnu one-lap car 530whp on the stock intake)
(3) don't overboost
(4) pay attention to warmup/cooldowns

And you should get a buttload of mileage out of your evo.

 

I think driver has much more to do with engine life than mods (withen reason) just make sure the mods you do are with quality parts if you do intake make sure the filter is a good filter that will clean the air not just allow more through, if you chip it make sure the chip is programed right etc. Good mantanence, care and responcible driving and quality parts will keep your car running.

 

You can use a lot of nitrous, provided the motor is built for it. Usually nitrous and turbo isn't a good combo because they add a lot of cylinder pressure.

You can do it, but not the way it is setup from the factory.
