I have a brand new EA28R-550 bolt on turbo. Bought it to use with my Q5 ( I was going to modify it to fit) but my plans with this build have changed as I need more low end torque to tow my newly purchased trailer. It is posted on eBay so here is the link https://www.ebay.com/itm/115761752932
I can sell it for less than this via private sale but on eBay but they take a pretty large chunk of change to list and sell an item. Best way to get a hold of me is to message me on Ebay but I will try to check my messages here as well.

It has a billet 53mm/71mm compressor wheel same as a GTX2871R







This image is of the EA28-500 , which is rated for 500 hp. The model I am selling is the 550H ready for 550hp

Hope this can help some people out!
