yes you can turbo it, but you have got the worse platform im afraid, its much easier to do it with a 1108 rather than an 899 so i would sell the 899 and get a 1108 then go from there, looks at FAQ's/guides etc, with all newbies we dont like to spoon feed and appreciate some effort from yourself in researching the matter
There isnt a lot out there mod wise now as by the time you are done, you will only be as quick as a 1108
Also unfortuneatly its now easier to buy a vehicle that is already turboed, and the cinq is getting ready on in years and there are much better and faster things available for what it would cost to turbo it
