Types of LBZ Duramax Upgrades

There is probably a lot of room for upgrades in almost any car. From wheels to the engine, everything can be upgraded, and performance can be enhanced. But that simply requires a lot of investment. However, if you are on a limited budget, you might want to prioritize your upgrades.

The engine should be your first priority if you are looking for an upgrade. It is probably because it is directly related to the performance of your vehicle. Upgrading your engine with quality components will yield higher performance. Moreover, it would increase the lifespan of your vehicle’s engine.

Here are some upgrades that you can perform with the LBZ Duramax engine.

One-Piece Y Bridge

Replacing your stock two-piece Y bridge can significantly enhance your engine’s performance. Typically, a stock two-piece Y bridge is held together by two O-rings. If you run enough boost, you can blow those O-rings and suffer from boost leak. Installing a one-piece Y bridge can be effective in eliminating this possibility.

Water Pump

A water pump can be a great addition to your Duramax engine. There are a lot of efficient water pumps with gaskets available to prevent your engine from overheating. As a result, your vehicle engine lifespan and performance will increase.

Fuel Lines

Another great upgrade to the LBZ Duramax could be installing newer and better fuel lines. They can significantly improve performance while being cost-effective.
