Installing HSW (Hao's Special Works) upgrades is a feature exclusive to the enhanced version of Grand Theft Auto Online on PlayStation 5 and Xbox Series X/S. The core process involves driving your car to the HSW Performance Shop located inside the Los Santos Car Meet. Once there, you can select the vehicle and choose from a variety of exclusive performance upgrades, including engine, brakes, and a unique HSW Boost for rockets on certain vehicles. This requires a significant amount of in-game money, specifically GTA$ and Hao's reputation points.
Before you can start, you must first complete the introductory mission, "The Pursuit Series," which is triggered by a call from Hao. This unlocks access to his shop and services. The upgrades are not available for every car; only specific vehicles designated as HSW-capable can be modified. You can identify these cars in the game by the "HSW" icon on their website listings or in your garage.
The table below lists a few examples of HSW-capable vehicles and their upgrade costs to give you an idea of the investment required.
| Vehicle Model | Approximate HSW Upgrade Cost (GTA$) | Notable Upgrade |
|---|
| Karin S95 | $1,700,000 - $2,200,000 | HSW Boost & Handling |
| Pfister 811 | $1,400,000 - $1,800,000 | Top Speed Increase |
| Bravado Banshee | $1,500,000 - $1,900,000 | Full HSW Package |
| Declasse Tulip | $900,000 - $1,300,000 | Engine & Brakes |
| Imponte Phoenix | $800,000 - $1,200,000 | Basic HSW Performance |
After purchasing the upgrades, the performance difference is dramatic. The HSW Boost, in particular, functions like a nitrous system, providing a massive burst of speed. Remember, these modifications are purely for in-game performance and bragging rights in races. It's a pay-to-win mechanic that significantly enhances your vehicle's capabilities within the confines of the game.
