Can anyone provide the performance specs of the 3.5L ecoboost turbochargers? Are they the same on the various versions (325HP, 365HP, 450HP)? I want to find upgrade turbos for the 450HP Raptor engine. Are there any plug-and-play, or will it be necessary to build an adaptor to fit onto the Raptor exhaust manifold? I'll be installing in a kit car, so I don't care about intake/exhaust configurations -- they will be custom built. Thanks for any advice/discussion.

Various turbos havwe bee used since 2011. Are you asking what would be an upgrade to the Gen 2 Raptor turbos?
What are your power goals? Do some searching on here, all the info is in the forum.

correct me if im wrong, but arent the stock ones basically ko3s and the raptor upgrades are ko4s?

I have to ask why you're using this engine in a kit car. There are so many other power plants out there that will make the same or more power cheaper and easier and sound better doing it.

I am not sure on the sizing but I know Gearhead tuning was testing some Raptor turbo upgrades.
