This car as of now has a 3800L, 2 Series V6:
^it has slightly different rims since, and some other changes since thats not an LTZ
But take that drop in a 3800L, 3 Series V6, GM crate motor, with heavy duty transmission, which is the same engine supercharged, get chip reprogrammed to change the shift points add some HP, and most importantly remove the speed limiter, and get some headers and pipes to top that off total it would add about 100HP to the car, from 200 to 300HP. And the car has 140,000 miles on it. When I drive I wish I could do this, cause my dads got the lumina ltz, and the grand prix gtp has the same exact engine on ly supercharged so thats why you can buy the motor from GM. And the motor plus trans is about $2,500
So, what do you think about that plan, after that really long run-on sentence lol?
heres a vid of what the exhaust whould sound like...
