Help with LS to T5 Bellhousing Swap?

Performance & Modifications
1

I’ve been diving into a project to swap an LS engine with a T5 transmission in my classic car, but I’m a bit lost when it comes to the bellhousing situation.

What I Need to Know:

  • Compatibility: What specific bellhousing do I need to mate the LS to a T5? Are there any particular brands you recommend?
  • Components: Besides the bellhousing, what other parts will I need for a smooth installation?
  • Installation Tips: Any advice on installation techniques or common pitfalls?

Sharing Experiences:

If anyone has gone through this process, I’d love to hear your experiences.

  • What worked for you?
  • What didn’t?

Final Thoughts:

I’m excited about this project but want to make sure I do it right. Any help or insights you can offer would be greatly appreciated! Thanks in advance!

I’m considering an LS3 for my T5 swap. I’ve heard it meshes well with the right bellhousing. Any thoughts?

3

I think LS1 and LS6 are also good options for a T5. You just need to ensure you get the correct bellhousing for the model you choose.

4

What about modifications? Do I need to adjust the input shaft or anything?

5

Yes, depending on the bellhousing, you may need to trim the input shaft slightly. It’s not a huge job but necessary for a proper fit.

6

What about the flywheel? Does that need changing as well?

7

Good question! You’ll likely need a flywheel designed for a T5 and the LS engine. A lightweight one can help with engine responsiveness!

I love the idea of a lightweight flywheel! It’s like putting a rocket on a 4-wheeler. Worth the investment!

Isn’t it funny how swaps can turn a simple car project into a full-on engineering degree? Anyone else feeling the same?

So true! But that’s what makes it enjoyable. Learning all the details makes the ride worthwhile!

12

But why complicate things? Shouldn’t we just focus on simpler upgrades? Sometimes I feel like it’s overkill.

13

Every engine swap has its challenges! I think it’s about what you want out of your ride, whether it’s power or simplicity.

14

Exactly! Each choice is unique. Just be prepared for a little tinkering along the way!

Looking to swap an LS engine into a T5 setup? You’ll definitely need a quality T5 bellhousing. Make sure to check the alignment with the clutch; misalignment can lead to major headaches down the road.

Great tips! Also, don’t forget about the appropriate tools like a torque wrench and alignment tool. Those make the job a lot smoother.

Don’t skip on the pilot bearing! It can be a common pitfall that causes noise and vibration. Invest in a good one when you’re doing the swap.

18

Very true! Also, ensure the headers clear the T5 bell. I’ve seen quite a few folks struggle with that.

Take your time with the wiring harness too. Merging LS wiring with older cars can get tricky. Label everything to avoid confusion later.

Absolutely! A wiring diagram can save you hours. You’ll thank yourself later when everything just clicks.
