Overview of the TBSS Intake Swap Kit

The intake manifold swap for the Trailblazer SS (TBSS) is a popular modification among enthusiasts looking to enhance performance and optimize engine airflow. This guide provides an overview of the swap process, essential components, and some practical tips to ensure a smooth installation.

Why Consider the TBSS Intake Swap?

  • Improved Performance: The TBSS intake manifold is known for its superior airflow capabilities, which can lead to better engine performance.
  • Enhanced Torque: Many users report noticeable improvements in torque, especially in the mid-range RPMs.
  • Aftermarket Options: There are several kits available on the market that cater specifically for the TBSS intake swap, making it easier to source all necessary components.

What You’ll Need

Before diving into the swap, here’s a list of components you should consider:

  • TBSS Intake Manifold Kit: Make sure to choose a reputable brand that includes all needed gaskets and hardware.
  • Fuel Injectors: You may need new fuel injectors depending on your power goals and the existing setup.
  • Throttle Body: A larger throttle body can provide even better airflow when paired with the TBSS manifold.
  • Miscellaneous Supplies: Don’t forget about vacuum hoses, adapters, and any other small parts needed for a complete installation.

Steps to Perform the Swap

  1. Preparation: Make sure you’re working in a clean, well-lit area and have all your tools at hand.
  2. Disconnect Battery: For safety, always disconnect the negative terminal of the battery before starting work.
  3. Remove the Old Intake: Carefully remove the existing intake, keeping track of all screws and components to ensure nothing gets lost.
  4. Clean the Surface: Before installing the new TBSS manifold, clean the intake mating surface to prevent any leaks.
  5. Install the TBSS Intake: Follow the manufacturer’s instructions to install the new manifold, making sure to torque all bolts to specification.
  6. Reattach Components: Reverse your previous steps to reattach any components removed during the process, including the throttle body.
  7. Reconnect Battery and Start: Once everything is back in place, reconnect the battery and start the engine to check for any leaks or abnormalities.

I’ve completed a TBSS intake swap on my Silverado, and it made a huge difference in throttle response! You’ll need the intake manifold, throttle body, and some adapters for a smooth fit.

That’s awesome, jacobwatkins! What adapters did you use? I’ve heard some can be tricky to get right.

For my swap, I used the Fast 102mm throttle body with the TBSS manifold. The fit was perfect, but I had to modify some brackets for clearance.

Thanks for the tip, mblack! I didn’t realize that would be necessary. Did you document your process anywhere?

I purchased a full TBSS intake swap kit which included everything I needed. Having all the parts labeled really helped during installation.

Great advice, rsaunders! Any recommendations on where to buy a complete kit? So many options out there.

I found mine on a reputable performance parts site. It was pricier but came with a warranty, which was nice for peace of mind.

Good to know! I often worry about quality with online purchases.

10

It’s essential to ensure compatibility with your vehicle model. Some intakes may fit specific years better than others.

11

Exactly! Always check the manufacturer details first. A friend learned that the hard way!

12

Oh, don’t even get me started! I had a fitment nightmare with my old car’s intake. The right manifold can be a game changer though.

13

Haha, I can relate, mkelley! But no pain, no gain, right? When it’s done, the power increase is definitely worth it!

14

Yeah, and make sure to use new gaskets! It’s a small expense that can save a lot of trouble later.

What if you just swapped the manifold and didn’t change the throttle body? Still worth doing?

That’s great advice, Adrian! I would also suggest having some rags and a container for any fluids that might spill. Keeps the workspace clean!

I found it very helpful to label hoses and connectors as you remove them. It’s easy to forget where they go later! Trust me, it saves time during reinstallation.
