I’ve been diving deep into the specifications of the LQ4 and LQ9 engines as I’m considering a performance upgrade and potentially an engine swap for my Chevy truck. Both engines are well-regarded, but I’m trying to figure out which one will give me the best performance gains for my investment.
Key Specs
LQ4
Displacement: 6.0L
Horsepower: 300 HP
Torque: 360 lb-ft
LQ9
Displacement: 6.0L
Horsepower: 345 HP
Torque: 380 lb-ft
From the get-go, it seems the LQ9 has a bit of an edge in the horsepower department. But horsepower isn’t everything!
Performance Characteristics
While the LQ4 is a solid engine, many enthusiasts lean towards the LQ9 for its performance. Here are some considerations:
Power Delivery: The LQ9 typically has a wider power band. This could mean better acceleration and responsiveness, especially if you plan on doing mods.
Aftermarket Support: Both engines have a variety of aftermarket modifications available, but the LQ9 may have more options due to its popularity in performance circles.
Fuel Economy: If you’re daily driving, the LQ4’s slightly less horsepower might offer better fuel economy, but it varies depending on how you drive.
Input Needed
If you’ve had experience with either engine, especially in applications similar to mine, I’d love to hear your thoughts!
Who’s used the LQ4 for towing or hauling? Did you miss the extra horsepower?
Has anyone boosted their LQ9 for even more performance? What mods did you start with?
Are there notable issues with either engine that I should be concerned about?
Conclusion
At this point, the LQ9 seems to be more appealing for someone looking to push for higher performance. However, I would like to gather more info before making a decision. What do you all think? Which engine would you choose, and why? Let’s discuss!
I’ve been researching the LQ4 and LQ9 engines as well. The LQ9 has a higher compression ratio, which translates to better horsepower and torque overall! Typically, the LQ4 sits around 303 hp while the LQ9 can deliver around 345 hp. Pretty significant difference!
In real-world settings, I’ve noticed that while the LQ9 shines in town and highway performance, the LQ4 is generally more reliable and easier to mod without breaking the bank. It really depends on what you’re after!
I’ve had my LQ9 for a year. The power is exhilarating, especially on the highway. I often tow with it and can’t believe how well it performs under load! Torque is insane.
Performance-wise, in stock form, the LQ9 often feels quicker. However, the LQ4 is easier to tune up. You can get more bang for your buck if you know what you’re doing, especially with mods!
Both engines have a decent aftermarket support, but the LQ4 definitely has more options. A turbo or supercharger on an LQ4 can bring serious firepower without needing to start from scratch!
LOL, I’ve heard LQ9s can scare off some unsuspecting competition with just their raw sound! How much tuning do you think is necessary to unleash their full potential?
It’s fascinating how preferences and needs vary. I think it boils down to one’s use case. Both engines have their strengths and weaknesses, and it’s great to see so many perspectives here!
I’ve been researching both engines, and it seems the LQ9 generally has a higher price tag due to its performance. Availability also varies by region, so check your local listings.
I’m leaning towards the LQ9 for its potential power. However, the LQ4 is more budget-friendly. I wonder if anyone here has upgraded an LQ4? What has that experience been like?
The LQ9 does have a reputation for being the muscle engine, but the LQ4 can also be built nicely. It really depends on how much you’re willing to invest.
