What Parts Do I Need for an S10 LS Swap?

I’m planning to do an LS swap into my Chevrolet S10 and could use some guidance on the parts I need. I’ve heard that this is a popular upgrade, but I want to make sure I’m getting everything right to avoid headaches down the road.

Here’s what I’m thinking:

  1. Engine and Transmission: I know I need an LS engine — possibly a 5.3L or 6.0L — and the corresponding transmission, but I’m unsure about which ones fit best.
  2. Mounts: Do I need specific engine mounts for the S10, or can I use universal ones? I’ve seen some that are specifically designed for LS swaps.
  3. Wiring Harness: Is it best to buy a standalone wiring harness or modify my existing one? What works most efficiently?
  4. Exhaust System: What do you all recommend for headers? I’ve read that certain brands fit better than others.
  5. Cooling System: Should I upgrade my radiator as well? If so, what size or type do you recommend?
  6. Fuel System: I’m guessing an LS engine will require a different fuel pump than stock. Can anyone advise on what’s compatible?
  7. Other Essentials: Are there any hidden costs or mandatory upgrades I should be aware of?

Questions:

  • What have others experienced with their LS swaps in an S10?
  • Are there any reputable suppliers or kits that come highly recommended?
  • Any tips for a newbie attempting this swap?

I’m excited about this project but don’t want to rush in blindly. Any info would be greatly appreciated!

For a successful LS swap in your S10, you’ll definitely need engine mounts specifically designed for that swap. I’d recommend checking out the ones from companies like Dirty Dingo or BMR Fabrication.

Great advice! Don’t forget about the transmission adapter. You’ll need one to mate the LS engine to the S10’s transmission or you might want to consider a new transmission altogether.

Absolutely! Also, wiring harnesses are crucial. An aftermarket harness can save you headaches down the line. Companies like Holley offer some good options tailored for LS swaps.

I totally agree! But isn’t it also a good idea to replace the fuel pump? The LS needs more fuel than the factory one can provide. Just a thought.

Absolutely, kellywilliams! You should consider a higher PSI pump for LS engines. It’s essential to ensure you’re getting enough fuel pressure!

What about the cooling system? An upgraded radiator can really help with engine temperature during those long drives too.

8

Good point! A lot of people overlook that. You’ll want to ensure that the cooling system is up to the task of the LS’s higher power output.

Don’t forget about the driveshaft! The stock S10 one may not handle the power. Upgrading to a stronger driveshaft is crucial for reliability.

Definitely! And you might want to look at the rear end as well for better handling of the LS’s torque.

What about the computer? Are you going to use the LS computer or a standalone unit? It makes a big difference in how you’ll set up the wiring.

Great point! I think a standalone harness is great for ease of installation and tuning.

You all are really thorough! I would add that if you’re looking for power, consider headers and an exhaust system too. They can unleash a lot of potential from the LS engine.

I’m just worried about the cost of all these parts. Swapping to LS can get pricey real quick! Anyone done it on a budget?

I’d recommend looking into tuning options as well. Custom tuning can really help maximize your gains after you add performance parts.

Headers are crucial for improving exhaust flow. Don’t skimp on these; they can significantly affect your engine’s performance.
