Turbo upgrade

[Ricahrd]

hi could anyone help with advice on upgrading my turbos to a bigger size but to keep the original manifold? I don't know whats the biggest size that would fit in the back of the engine.

Nothing is a direct bolt on. Subaru wrx fitment td04s can be made to fit with less work than others. Have a search on the site there is a reasonable amount of info around.
