How would anyone suggest to give my 1990 760 GLE auto a little more go or make it go smoother ?
considered replacing the airbox with a cone filter not sure what that will do though . It has the V6 engine so was considering a Turbocharger if I can find one and a conversion.

Don't bother with a cone filter - the normal volvo filter is perfectly adequate until you do major modifications.
It might be worth improving/removing the pre-filter box piping though, as it's simple and free. (i'm only familiar with the 4 cyls, so can't picture the 6 cyl setup) Use of "ram air" is up to you, i'm skeptical about it, but cold air is ESSENTIAL (ie, make sure your air box is pulling outside air, not engine bay air).
Remove the hot air intake hose that runs from around the exhaust to the airbox - you don't need it, it kills power when drawing hot air (and reduces efficiency in warm climates), and makes no difference to warm up times.
Do a search for John Lane and his fire breathing monster over at turbobricks.com if you are really serious.... even if you're not, his car is incredible to find out about!
Unfortunately i don't think you've got many cams to choose from, like the 4 cyls, but you can get them ground to spec, and head work would make a large difference.
The stock exhaust will probably keep you happy for a while, it's certainly one of the last things i'd do.
As with most things, if you don't get really dirty doing the modification, you won't get much of a gain.

Before spending a ton of money "tuning" our Volvo engines, I would seriously consider swapping in a GM small-block V8 and 700R4 auto trans. It's been done quite successfully and leaves you with a reliable power plant that is much less expensive to work on than most any Volvo engine.
Don't anyone get me wrong - I am NOT knocking Volvo in any way. I wouldn't be driving one if I wasn't a big fan. If more power, reliability and driveability are the objectives though, one has to at least consider the idea.
A 350 V8 powered 240 has been on my mechanical "todo" list for some time now. If and when I get there I'll let you know.
By the way it's a (comparatively) simple matter to swap in a GM small block to any 80's or 90's rear-wheel drive brick including 240, 760, 940 and 960s.
