even if it is the same motor? can you explain why it won't work please

Expert:  Dennis replied 8 years ago.
They don't have the same engine. The Trooper has a 2.8 and the Olds has a 3.1, 3.8 or 3.4 liter engine. Besides that the computer systems that run the engine are totally different and would not even connect up. To adapt everything over would be VERY cost prohibitive. Better to just replace it with the same engine and engine management system. Thanks!
