Has it ever been done before

hi and welcome. multiple posts of the same question wont get a quicker response, it just gets them deleted. please be patient. it may take several days for the right people to see this.

my guess it that a turbo is a turbo regardless from which vehicle it came from. it should work just fine. if it's a stock unit, it may be a little on the small side.
