Thanks to Junior at Jaaatt Engineering in the UK, I've been able to get this bespoke part completed.
This one-off design allows the 2.5 throttle body to mate perfectly to the TTRS/RS3 plenum, while allowing proper clearance to the new MAP sensor location.
Why not just run the TTRS/RSE throttle body? Good question, the reason being that the F/I tune from United Motorsport does not play nicely with the larger TB size, and they are unwilling to support this platform with custom tuning. In order to run the TTRS/RSE TB, you'd need to move over to a stand-alone ECU setup such as EMU Black and custom tuning.
In the future, that will be my goal, but for V2 of this setup, I'm going to see what we can squeeze out with 1000cc injectors and the UM F/I tune. More to come soon, as I'm still awaiting a few one-off parts.
