Different turbos for GReddy Kit? BEGi DP fitment issues
 

So I helped install a GReddy BEGi downpipe on my friend's Miata. The flange for the DP didn't cover the whole exhaust side of the turbo and so there is a exhaust leak. I recall that GReddy might've changed the turbos that they included with the kit midstream; what's the difference, and could this be why the DP doesn't fit right?
