Your options are:
* Custom Fabrication: This is the most likely route. You'll need to source individual components (turbocharger, manifold, intercooler, piping, injectors, fuel pump, ECU, etc.) and have them custom-fabricated or adapted to fit your engine bay. This will require significant mechanical knowledge and likely the assistance of a skilled fabricator or tuner. Expect this to be the most expensive option.
* Used Parts and DIY: You might find some used parts on online marketplaces like eBay, Craigslist, or forums dedicated to GM cars. However, sourcing all the necessary components in good condition and figuring out how to make them work together will require significant research, time, and effort. This is also a high-risk approach.
* Adapting Kits: You might be able to adapt a turbo kit designed for a similar engine, perhaps a different GM V6 from a different year or model. However, this would still require significant modification and fabrication.
Before you begin: Seriously consider the cost and complexity involved. Turbocharging is a significant undertaking, even for experienced mechanics. You'll need a good understanding of engine mechanics, fuel systems, and tuning. Underestimating the project can lead to significant expense and potential engine damage.
In summary, there isn't a simple "buy this kit and install it" solution. It's a custom project that requires considerable time, skill, and resources. Research thoroughly before committing to this project.
