Yes mate.

Jenvey TB manifold
Jenvey TB blanks as spacers
RS200 Inlet Plenum
Aftermarket Trumpets inside plenum
Vectra V6 throttle body (same size as rs200 one)

To put it together we just knocked up an adaptor plate with a file and a drill and a saw on the bench at home, and made some gaskets the same way.

Parts cost was IIRC
Manifold + fuel rail : 300
Spacers : 200
RS200 Plenum : 125
Trumpers : 60
Vectra TB : 20
Gasket Paper : 5

So a total of around 700 quid, and Ive still got all the saleable parts if I ever want rid of it so should get most of my money back, or if I put the engine in something with less height room like a VX220, I can swap to a pulsar plenum instead very cheaply
