So im planning on going up under the hood of my car adding performance. I know its alot of options but im still not sure. I was thinkin about getting a newer l36 motor an adding a turbo, then i was thinkin about getting the full L67 motor and tranny swap and adding some performance parts along as well. But I just recently heard that a shop near me could do a LS4 conversion in 97 to 2003 grand prixs!! Has anyone done or know of some1 who has this conversion already put in a early model Grand Prix?? If so can u help with me with some advice or let me know if its even worth all the money im going to put in the project? Personally im a all motor kind of guy i was wanting alot of horse power but i know adding boost is a faster way to make your car have more power; any HELP would be much appreciated
