Hello Neil, Most cost effective way to improve the performance of your 1989 rangie? Trade it in! As has been stated, a 4.6 upgrade done properly wil set you back multuples of the value of the vehicle. Supercharging- around 10-12k. Even a 4.4, done properly, will cost probably double the value of the vehicle- that is the route I took with my 88RR a few years back- goes well, but had I known the final cost before I started, I would not have done it. The thing is that every other component of the vehicle will still be 20 years old. How many kilometres has your engine done? I would suggest that you are probably feeling the lack of power of a tired 3.5, as opposed to just a 3.5. I would advise that you pull the camshaft out of your engine and have a look at the lobes- they are probably close to round. You may well find that with a new cam and lifters, you are surprised by just how well a 3.5 goes. As far as add-on bits go, absolutely no point in adding things on to a tired engine. I'd be happy to discuss my experience of a 4.4 upgrade if you wish.
