First off in sorry if this is a re-post I searched and said my search was to narrow.

If I can't resolve my engine issue by next Friday I want to replace my engine or upgrade to F20b. Now my question. Anyone know who's who in the JDM engine market? Like who is the best company quality is the top issue an concern for me. Like all of you I'm sure you don't wanna spend your hard earned dollars on something that is worse than what you are replacing or needs a rebuild within a few months. In advance thank you for your time opinion and experiences.
