Just out of curiosity, with proper care, and maintenance, just how long will the EJ20 last?
Are we looking at an engine that will go 200,000+ miles?

I know the engine has been around in the subaru family for roughly ten years or so, so I am sure it is very well engineered, but how long will a stock EJ20 last?

 

The EJ20 will last as long as any other good Japanese engine. Just do the proper maintenance and do not push it too hard, I'm sure you can reach your 200k+.

 

100,000k+++ easily, I've read stories about lots of people getting up there. 200,000K i havent heard yet though.

 

I got 96k and have never had an issue......And I drive hard....

*knocks on wood*

 

119k w/mobile 1 every 6k. I think i'll change my timing belt soon and maybe get an uppipe.

 

i change mine every 3k. do you think i should do it less frequently?

sorry for the OT.

 

I got 250k miles out of a Ford 4cyl 2.3 EFI Turbo in a stock Merkur XR4Ti. It also made 14.5 pounds of boost. It would blow a fitting here and there, but these were usually obvious things you could fix by the roadside in a minute. I never had one minute of mechanical trouble from the engine or turbo, not even once. Mobil One all the way, every 3k. Turbo spooled a little slower, but still gave plenty of boost. Plenty of compression in all cylinders. No sludge. Had a second Merkur that was as good. I would not doubt that the Subaru EJ20T is mechanically at least as good. At least that is what I tell myself, having just bought a MY02 WRX sedan...today. It was very clean, almost like new with 55k miles on it.

the answer is:

163,000 miles.

thats where my totally stock powerplant finally burned the exhaust valve on cyl #4

I will be curious to hear if anyone gets one to last longer....

 

i do mine every 5k or so. i remember a study by consumer reports that looked at ny taxicabs and checked them at 3k and about 5k or 6k. the difference was almost indistinguishable. the only people who benefit from 3k oil changes are the oil companies and places like jiffy lube (who are the ones who recommend the 3k changes). obviously you are not hurting you car, just overkill imo.

 

owner manual says 7500 miles. i think that is a little bit too much.

 

ive got 151,000KM in my 99 sti.
No problems as yet.

 

at 93,000 miles, I didn't have any problems then either.

Let me know when you hit 262,000 km

 

The EJ22 in my Legacy has 117k miles on it and so far so good.

 

Yer I had a 1995 impreza 1.8ltr it had 360,000 kms which converts to 226,000 miles
