XV engine swap


Recommended Posts

Hi there,

My turbo recently gave up and more investigation is required to check the sump for any white metal from the crank shaft and main bearings as a precaution 🥴 excuse my lack of knowledge on engines but this is what I’m told by the Subaru garage.

Anyway, I was thinking if it leads to more than just a new turbo required and going to cost a fair bit then it might be a good opportunity/good excuse to swap out the engine 😬

Its a 2016 XV 2.0 turbo diesel. 
So, what I was thinking was SORN the car and convert it to petrol (toying with the idea of a rally car). Now I know it’s not just as simple as engine out, new one in, even when it’s same fuel type. 

My main question is, would a 2015> 2.5L STI engine fit in the 2016 XV engine bay?? I’m guessing both models have the same chassis and hoping that it’s possible 😅

Any feedback would be greatly appreciated.
Thanks in advance!

Mark 🙂

Not sure about the engine layout as not familiar with the XV but given the Subaru diesel plant is not the best I think the idea of a petrol conversion is a good one.

Not sure how a turbo failure means crank and bearing wear? I could understand if the blades disintegrated and went through the engine there would be damage though - How bad was the failure?

Before you give it to a garage for investigation why not get some of the oil and send it off for analysis - That will then tell you if you have any ring, crank / bearing wear. Its a relatively small cost before a garage starts pulling things apart.
