The 2003 Cadillac Deville is equipped with a DOHC 4.6 litre V8 engine rated at 275 horsepower. There is a lack of aftermarket support for the Northstar engine, so there are very few options i the way of performance improvements. I am of the understanding that any car can be turbocharged and, although I understand the basic principles of turbocharging, I have not worked on a custom turbo application. My questions are: 1. Would a custom turbocharged or remote turbocharged setup be possible with this car? 2. If so, how much would this project cost? 3. Where can I learn the instructions to make a custom turbocharged installation (I have experience with automotive mechanics)? Thank you.
