Thinking About a Blown LS Crate Engine for My Build - Advice Needed!

Performance & Modifications
1

I’m considering upgrading my vehicle with a blown LS crate engine, but I’m not sure where to start. I’ve been doing a bit of research and it seems like there are so many options out there that it’s overwhelming. I’d love to get some insights from anyone who has experience with these engines.

What I’m Looking For

  1. Performance Specs: What kind of horsepower ratings should I expect? Are there specific numbers or benchmarks I should aim for based on my intended use?
  2. Manufacturers: I’ve noticed several manufacturers producing blown LS crate engines. Any recommendations on which brands are reliable or provide the best value?
  3. Compatibility: What do I need to consider regarding compatibility with my current setup? Are there specific modifications or upgrades that I should plan for if I go with a supercharged option?
  4. Installations: For those who have swapped in a blown LS engine, how was the installation process? Should I attempt it myself or seek professional help?
  5. Best Practices: Any tips for maintaining a blown LS setup? I’ve read that these engines can require more attention than stock ones, so I’d appreciate any advice on that front too.

Conclusion

I’m really excited about the potential of a blown LS crate engine, but I want to make sure I’m making an informed decision. Any tips, resources, or personal stories would be greatly appreciated! Thanks in advance for your help!

If you’re considering a blown LS crate engine, definitely look into a quality turbocharger upgrade. A larger turbo can significantly boost your horsepower without compromising efficiency.

Totally agree with you, davisgene! I’ve seen turbo setups push engines to over 700hp. Just make sure you match it well with your intercooler and fuel system too.

Intercoolers are key for maintaining power. Look into front-mounted intercoolers—they perform way better than stock ones. Keep those intake temps down!

5

Great point, joshuamurphy! A good intercooler truly makes a difference. Besides, don’t forget about upgrading the fuel system to handle the extra power.

6

Absolutely! Fuel pumps and injectors need to be upgraded, otherwise you’ll be starved for fuel. Look for high-flow options to match your boosted setup!

7

Speaking of upgrades, have you thought about tuning? A good ECU tune is essential to maximize performance.

8

For sure! Tuning can unlock a huge chunk of horsepower. Just don’t cheap out on the tune—a bad one can ruin your engine rather quickly!

Right?! I learned that the hard way. Let’s not talk about my last project, lol.

Another thing to consider is the exhaust system. A decent set of headers can really help the engine exhale efficiently.

11

Good point, afoster! I went with long-tube headers on mine, and the difference was night and day. A free-flowing exhaust makes a huge impact!

12

How much did you notice that change on the dyno? I’m curious about actual numbers here.

13

Honestly, I saw a gain of about 50hp just from the headers and a straight pipe. The engine loves to breathe! Just be careful about noise levels.

14

That sounds awesome! Though, the sound might be what gets you pulled over more often, haha.

Haha, true that! But if you’re careful, it’s a risk worth taking for the horsepower gain. All the mods can really add up, but man, it’s fun to drive!

16

Installing a blown LS crate engine can be fantastic, but make sure you have the right tools on hand. You’ll need a good torque wrench, engine hoist, and a variety of sockets. Don’t forget safety equipment too!

17

Absolutely! And definitely make sure you have a lift or jack stands for better access. Lifting the car will save your back during installation.

18

Common pitfalls include rushing the installation and not double-checking clearances. Take your time with aligning the engine and checking all fluids before starting the engine.

19

Totally agree! Also, keep a dedicated spot for every tool you use; it prevents losing important pieces mid-build.

A tip is to document your steps with photos as you go along. You’ll appreciate having that later if you need to troubleshoot or re-assemble.
