I may be selling my turbosmart eboost street boost controller shortly. Was bought from MSD and only covered 3k miles.
I'm now going with OFAM management so will be controlling boost via the ECU.
I will be keeping the boost solenoid, so all you would need is a new boost solenoid and you would have a complete kit mate.
Let me know if you are interested.
If you look up MSD's site you can see the spec, pretty sure James runs the same in his new Cossie!
