Motor Replacement Options

I have a 2011 Ralliart (JA32V6FV9BUXXXXXX) that I picked up cheap and found that I have low compression on all cylinders. Looking for a replacement and want to know what my options are. Will anything from an 08-11 work as long as it's 4B11? Could I drop something out of a Evolution in it.

Since this one is a AWD Automatic is there anything I need to know about swapping a manual in?

4B11T. Ralliart motor and evo motor are the same.

Yeah, that's what I've found too. I also found that the exhaust manifolds are different from Ralliart to the evo. So that's what my concern was.

RA and X blocks are the same. It’s the accessory stuff that’s different. 4B11 is not the same as a 4B11T so do not try to get one of those as it will blow right away since they’re not meant to handle boost

yes the exhaust manifolds are quite different. If you’re just replacing the engine then one from an Evo X will fit, we have the exact same block as the Evo X. Engine code is 4B11T.

Could you elaborate on what you meant that the 4B11 is not the same? Aren't they the same block just with a turbo? What's different besides the manifold?

What he meant was that the 4B11 engine is totally different than the 4B11T. The 4B11T come with the turbo lancers ie: Ralliart and Evo. Do not get a 4B11 get the 4B11T. Everything is different from the 4B11 to the 4B11T. I say again, get the 4B11T. What are your compression numbers btw?
