I have a 1994 Dodge Shadow ES 2.5L non-turbo I just had the transmission rebuilt and a got a new CV joint on the right. But the problem is before I took the car in to be worked on I had gotten it up to 110 and didnt top out but now i have it and it tops out at 85 in drive so i checked and it tops out at 85 in second also!!!! i cant figure it out and either can anyone I asked. PLEASE HELP ME!!!!

also, i forgot if i get the problem fixed and everything is back to normal.. can i take a old turbo shadow's turbo and put it on mine to get the same affect???

Nope, the old Shadow had a 2.2L with forged interanls. If you want the effect you will need an intercooler, engine swap, and the turbo.
