Engine swap help


Recommended Posts

I have a 2006 Subaru Legacy 2.5I limited, A week ago the motor went out. There is a hole in the block, and two of the connecting rods are snapped. I would like to do the Legacy GT motor instead of the original, I found a complete motor along with wiring harness and ECU. How hard is the swap? I was told it is relatively easy, but really how is it. How feasible is it? How much do I have to tear out to replace wiring harness? The GT motor is from a 2005, with the automatic. My car is an automatic.

As said, it's not worth the effort.

 

If the body is in great shape, buy a rebuilt engine from some place like Jaspers if they are still in business, or ask google where to get a 25i engine or a ej253.

305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).  CHECK your oil, these cars use it.

If you want to do a swap with this much work would be awesome in a much older legacy or gl wagon, 90's Impreza excetera

 

Legacy GTs are worth very little right now, better approach to getting a running legacy gt and some wrench time would be to buy a gt with a blown motor and a do a rebuild

Interesting. Is that true?

Yes I see them all the time for less than 2k with blown motors , and you really don't want to swap in a used 2.5 turbo as they have a lot of failures.

 

So new short block at least would be a good idea.

 

Not my first choice but a JDM 2.0 turbo is a much and option with a legacy GT and doesn't require all that much work

complete engine with ecu & wiring harness?

from what car?

did you get the biu & steering column & keys & rest of the wiring harness?

you'll want the brakes too

probably the transmission too

 

doing the engine swap is pretty easy. harbor freight crane and a couple of jack stands. basic set of tools. some drip pans and buckets for water & oil.

 

getting the wiring pulled and connected is a pain but not impossible. iwire services has a number of wire harness options to make the swap easier.

 

it's been 17-18 years since an mt lgt was made. about half have been crushed. finding one in running condition is getting harder. 7000-15000 for one in good condition.

 

doing this swap if you've never worked on cars before is going to be difficult. however ppl do it all the time.

Oh okay. With a blown engine. Having a car almost be worthless if it doesn't have a working engine is not unusual.
