Its a stage in a long project, to get some more power & torque out of the 3.2 ltr lump. I've purchased an intake plenum which I've ported & polished.(as above) However when I initially opened it up, only then did I realise how gunged up this thing gets, so I am bypassing the egr (I fitted a bypass rather than just blanking it off, due to fact that it throws error codes or the eml, doing it this way keeps the process pretty stock & keeps the ecu happy with no errors or manifold pressure problems) to eliminate the hot sooty fumes & also in the process of fitting an oil catch can. Once they are both fitted, I can fit my pristine intake plenum. After that, Ill be fitting a CAI, to go with the 74mm throttle body & Maf. Next will be slightly larger injectors followed by a remap.
