power steering is easy as pie, 4x4, well its been done in different ways but its far from easy and if you planned on paying someone to do it for you then i hope you have very deep pockets!

as for 350-400 bhp, mate, im sorry to bust your bubble but look towards the 250bhp mark, other wise you going to be spending so much your be better off putting that money into a £20k escort cossie and still have change!
