i dont know if there is already a thread for this or not but i was wondering will an evo 8 turbo work on our ralliart without any major modifications??

 

I presume you would need the Evo X manifold and all that jazz.

 

The simple answer is no. That turbocharger comes from a different family of turbochargers (TD04 vs. TD05 I am pretty sure). It would probably be easier to swap in the EVO X turbo, although they are both twin scroll. I guess it doesn't really matter.

EDIT: This is a pretty decent guide to MHI turbochargers:

Evo 8 owners can and do readily swap in the 9 turbo so what family it comes from is irrelevant, the mounting side is the same. An easy way to check is to see if Evo 8/9 owners can use the X turbo.

 

It could probably be done, but it would be a lot more work than it's worth. You would need a different manifold (and I don't think the EVO X would work... maybe it would), and the EVO VIII and IX turbos are from different families than the EVO X. I believe that they are reverse scroll, where the EVO X's is not??? Some of the Mitsu gurus can confirm or deny that. Either way, the reason the VIII and the IX turbos interchange is because, I believe, they are the same turbo, same manifold, same 4g63, same engine bay layout, etc.

Since the RA has the same 4b11T as the EVO X (there has been some debate over whether the RA has the same injectors, but for this, that is a moot point), the same engine bay layout, the same clearances, etc., and ESPECIALLY since the EVO X turbo is just better than the turbo on the VIIIs and IXs, just do the EVO X turbo swap.

 

Its a reverse scroll so no, not to mention turbine side design is totally different.

Yeah, but I am pretty sure that the whole thing is reversed. Either way, I doubt that it would be worth anyone's time to use the turbo from an VIII or IX.
