Raceport BOV finally arrived!!...
Bought from an authorised Turbosmart distributor in the states so I can be assured its genuine!! It's smaller in the flesh than I'd anticipated but that's probably a good thing! However, I'm starting to reconsider mounting it on the plenum, just after the intercooler hose as this will keep vac lines to a minimum as well as keeping it away from any nasty water/FOD.
Going out to the garage in a mo so will have a mull over it and make a decision!!
Now have all sensors apart from Lambda and crank/cam wired and routed to the passengers footwell in readiness for the ECU. Once again, it seems that the list of jobs I can be getting on with is VERY small which means I must be doing something right
