the prototype SVC/Cameron Concepts Supercharger kit for a Disco2. should fit SAI if you flip the drivers side pipe/solenoid valve over and reroute the air tube. May fit a P38 but this was supposed to fit a D2. This is the only one known to exist as it was sold off after Cameron passed away.
For BOSCH intake manifold. no reason it cant be made to work on a defender with that.

7lbs boost IIRC
Eaton M90 Short Snout (rare)
SplitSecond 9th/10th injector controller, land rover guy told me years ago that the factory fueling would hold 5lbs of boost
The idle bypass valve has a broken nipple, but they are 40 or so from summit for a new one. I have most everything else to install save for any small hoseclamps or hardware. I never installed it.
This is the prototype so it has a few rough cast pieces.
I sold off my rovers and I don't think my mom wants this on her D2....
***I never ran this but I did mock it up most of the way years ago.
$1000 shipped. OBO. I'm in it for $1200
