Question EJ20 Swap longevity?

I about this || close to pulling the trigger on an USDM EJ20 swap into my 2000 Legacy GT 5mt. The tranny is good, body and interior are nearly perfect, the rear diff and axle are good, and there is no rust underneath. I'd replace the suspension and probably the front axle when the swap is done, and definitely a new clutch too.


I only put ~12k miles on my car a year now, and although I'd probably add a few mods gradually after the swap, nothing crazy to put down huge power.


If I do this I'd be committing to the car long term -> 4-5 more years. Is this reasonable to assume on a swapped car assuming normal preventative maintenance?


Thanks in advance

A full swap will last you longer than a modded engine since the swapped engine comes from the factory that way. I don't see why it wouldn't last as long as any other suby engine (long time)

I tall depends on how the Ej20 was treated in it's former life. If it was stock and low miles, expect it to last as long as if it had stayed in the WRX. If it was tweaked and boosted hard, that's a whole nother story. But a swap is an OEM replacment and should be OEM reliable...

Thanks guys, excellent points. Aside from what I've pointed out, anything preventative you would do at the time of the swap to help w/ longevity for the rest of the car?

If you plan on a TBE exhaust and an ECUtek or Cobb reflash, a fresh clutch and pressure plate would be in order at the point of swapping. Also, a close inspection of things like cam seal, rear main and any other areas that might be leaking some oil would be in order...

The clutch would be done. I would be getting the swap done by ECS and they include the choice of either Exedy or ACT disk as part of the parts/install.

Make sure to have a catless uppipe. Thats one of the few issues the USDM EJ20's have had, with the cat failing and getting sucked up into the turbo/engine causing issues... Better safe than sorry.

Thanks. I had thought about that as well as a downpipe too to help with turbo lag and more low end.

Also, make sure you get everything for the swap in advance. I have seen a couple of cars sit literally for a month or more while they shopped for a power steering reservoir and lines of all things. Buying a complete swap saves time and money...
