WOW , that is unfortunate.

 

I had a motor let go with very minimal mods only exhaust intake fuel pump and uicp never was able to diagnose the cause of failure crank bearing ended up scored and went ahead rebuilding the motor stock boost etc etc probably wasnt even making 300 car hadnt been tuned yet and wasn't being beat

 

yes

 

Ahem...you're describing a 8 year old, modified, untuned car that was purchases used, correct?

 

That could be your problem.

 

Stock engines blow all the time... with 100's of parts, not everyone can be 100% on 100% of all the engines ever made, **** happens, end of story the answer to your question is YES!!!!

 

I think pointless argument. Any car can break, but yet any car can be reliable if you take care of it the right way. Evos can be very reliable if you take care of them regardless of what anyone says because ive seen it happen.

 

Instead why don't you ask are stock Evos or very close to stock Evos reliable. The answer is yes. The Evo is a very reliable turbo car as long as it's not abused.

 

Ive seen them abused and be still reliable

 

This thread gets me sad. But for a turbo factory car that comes w/ such high boost on stock wg, they hold up well.

 

...and the opposite, not abused, blown TC, ACD pumps, spun bearings, pealed calipers, water intrusion to the cabin wiring harness..... what's your definitin of reliable, leaving you broken down at the side of the road, or things which have to be warranted and replaced?

Reliable is a highly subjective term, OEM's actually have an evaluation for it for PPHU, problems per hundred units... if you wanted to take a objective perspective especially because the volume of evo's isn't very high, I'd be willing to bet my paycheck that for Evo's that number is very high compared to vehicles like a Honda civic, which are made in the millions. I'd also be willing to bet with all the warranty items had to replace, they lost money as a whole for even making/selling the vehicle, as its to reflect brand image and identity. When something like brake caliper replacement for all 4 is like ~$4000, there isn't much margin for profit after that, I think my ACD pump was ~$1200-1400.... what about a spun bearing ,or TC, wiring harness (holy **** that'll be alot of man hours)?

To put it bluntly, very serious parts break on evo's, and some run 600hp on the stock engine/drivetrain and beat the **** out of it... Evo's are reliable as rolling the dice in some perspectives.

PS, I love my evo

 

Reliable is going over 100k without major breakdowns.
I'll give you the ACD pump issue. But blown TCs?
I'd bet 99% of all blown TCs are abuse or wrong oil or those that claim to not have abused their cars but learned stick on the EVO.
Peeled calipers is Brembo's fault.
As for water intrusion that's a problem that can be fixed easily with some RTV.

So two items out of how many systems on this, as you mentioned, limited production car?

 

Agreed. Some ACD pumps have been known to fail. Whether it happened after the ACD was not bled during a clutch install, etc remains a question. Blown TCs on cars that weren't abused - how many? Spun bearings on stock cars - how many? I've been here for almost 6 years. I can't recall seeing more reports of this than what adds up as the number of fingers on both hands. Water intrusion - a port-install issue confined to a small number of MRs.

Some early cars, yes. Others, being drenched in brake fluid, others, driven by the heat mirroring the surface of the Sun due to motor racing. This isn't a platform-wide issue. Nothing cited is.

 

Just to state, this isn't an argument before anyone wants to blow this out of proportion.

My car for one, 100% stock blown TC at 17K miles, I never beat on it, kind of sad.
My calipers pealed about at the same time, got those replaced under warranty, my ACD pump blew at 35k miles..replaced under warranty. My car was stock up until 52k miles, 95% all highway.
The calipers is 100% Mitsubishi problem, I know this because I work with Brembo, it is not their normal paint process, for example, how many other brembo OEM calipers are there in the market which don't peal? Just about everyone I've came in contact with.
The wiring harness is completely unacceptable, its not something the owner should EVER have to fix period on any car.
If I remember correctly on the Evo8's there were a decent amount of spun bearings going around, and especially blown TC's. By far Evo9's are the most reliable (no spider gear), but that is just in general. The items I listed were a handful of problems I've seen more than just a few times, there are probably a lot more issues if I searched for it. (harness issue I only seen 3 times total)...

Even though there are many systems on these vehicles, they are large high dollar problems, not little easy fix problems. On a limited production vehicle you expect the concerns to be much less, as you have fewer to make, that's why the statistic is PPHU, problems per hundred units.

 

Your comments piqued my curiosity, so I took a quick look at your past threads. It looks like you bought a used Evolution with ~11K on its clock. Your calipers were peeling, replaced under warranty. Short time later your TC was replaced by a built unit (edit - per post above, ~5,000 miles later), and a time later your ACD pump failed. The key words here are "used Evolution." I'm not trying to put you on the spot; just saying that a used Evo that went though who-knows-what before getting into the hands of caring owner many not be representative of well-maintained, unabused Evolutions as a whole.
