EJ257 single scroll to twin scroll conversion
Bought a Type UK '06 STI in May (obviously single scroll EJ257). Cooling issues from start, headgaskets blew. Taking the engine apart it turns out that the VF43's classical hot side crack is too extensive.
Now looking to do the twin scroll conversion. I have the turbo (VF49 with some mods), I have the headers and the up-pipe but now the question is:
What other parts I would need besides headers and up-pipe?
I have heard about the sump, possibly oil pump? Can you clear this out for me?
Regards,
Joonas
