1. ISR Performance KA24DE Turbo Kit: Top Pick
The ISR Performance KA24DE Turbo Kit is our top pick based on owner feedback and spec sheet analysis. It includes a T3/T4 50 trim turbo, cast iron exhaust manifold, front-mount intercooler, polished piping, blow-off valve, and wastegate. According to manufacturer claims, this kit supports up to 400 horsepower with proper tuning. Owner reviews report straightforward installation and reliable daily driving at moderate boost levels.
However, we found that the intercooler piping may not clear all radiator fans without slight modification, which could be a hassle for some users. This kit is best for enthusiasts seeking a complete, proven setup and who are comfortable with minor fitment adjustments. Skip this if you want a fully plug-and-play experience without any modification.
- Complete bolt-on kit includes turbo, manifold, downpipe, intercooler, piping, and wastegate
- Cast iron manifold resists cracking and supports up to 400 hp
- T3/T4 hybrid turbo provides quick spool and strong mid-range power

Cons: Intercooler piping may require minor trimming on some chassis
2. CX Racing KA24DE Turbo Kit: Best Value
CX Racing offers a budget-friendly KA24DE turbo kit that we evaluated based on published specs and owner reviews. The kit features a T3/T04E turbo, stainless steel manifold, intercooler, and all necessary piping. Many owners report achieving reliable 300-350 wheel horsepower with proper tuning. The stainless steel manifold is a plus for corrosion resistance.
On the downside, fitment can be inconsistent; some users needed to modify the downpipe or intercooler piping for a proper seal. This kit is ideal for DIY builders on a budget who don’t mind minor fabrication. Skip this if you want a premium fit-and-forget kit or plan to push beyond 400 hp without upgrading components.
- Affordable complete kit with stainless steel manifold and turbo

3. Garrett GT3071R KA24DE Turbo Kit: Premium Performance
This premium kit from Garrett (assembled by various vendors) centers on the legendary GT3071R turbocharger. Our research indicates this turbo offers exceptional spool and power potential, with many owners achieving 400+ reliable horsepower. The kit includes a cast iron manifold and essential lines, though the intercooler and piping are often sold separately.
The main drawback is the price, which can be significantly higher than other kits. Additionally, the kit may not include an intercooler, so total cost adds up. This is best for serious performance enthusiasts who want the best turbo response and are willing to invest. Skip this if you are on a strict budget or only need a basic 250 hp setup.
- Genuine Garrett GT3071R turbo with ball bearing for quick spool

Megan Racing’s KA24DE turbo kit is a popular choice for daily drivers seeking a reliable boost upgrade. Based on owner feedback, the kit installs with relative ease and includes a cast iron manifold, T3/T4 turbo, intercooler, and piping. Many users report consistent performance at 8-10 psi with proper tuning, yielding around 300 wheel horsepower.
However, some owners noted that the turbo’s journal bearing design may not tolerate continuous high boost levels above 12 psi. This kit is ideal for those wanting a dependable, moderate-power street setup. Skip this if you plan to track the car or push beyond 350 hp without upgrading the turbocharger.
- Complete kit with cast iron manifold, turbo, intercooler, and piping

According to owner reviews, with proper tuning and conservative boost, it can achieve 250-300 wheel horsepower. For the price, it offers a complete setup to get started.
However, the mild steel manifold is a known weak point; many owners report cracking or rusting over time. Fitment may also require adjustments. This kit is best for budget-conscious builders who are willing to upgrade components later. Skip this if you want a durable long-term solution or don’t have fabrication skills.

Owner feedback indicates it can work for a basic 200-250 hp setup, but many report issues with wastegate adjustment, boost leaks, and premature turbo failure.
This kit is best for first-time turbo builders on a tight budget who are prepared to troubleshoot and possibly upgrade parts. Skip this if you want reliability out of the box or plan to run more than 5-6 psi of boost. Safety concerns with boost control and component durability are significant.

Frequently Asked Questions
What is the best turbo kit for a stock KA24DE engine?
For a stock internal KA24DE, we recommend the ISR Performance or Megan Racing kit. Both are complete and designed for moderate boost levels (8-10 psi) that are safe for the stock bottom end. Always use a proper tune and intercooler to prevent detonation.
How much horsepower can a KA24DE turbo kit make reliably?
Based on owner feedback and manufacturer data, a well-tuned KA24DE on stock internals can handle 250-300 wheel horsepower reliably. With forged pistons and rods, kits like the Garrett GT3071R can support 400+ hp. Reliability depends on tuning, fuel system, and boost management.
Do I need to upgrade my fuel system with a turbo kit?
Yes, most turbo kits require upgraded fuel injectors (370cc or larger), a higher flow fuel pump, and an engine management system (e.g., Nistune, ECU flash) to safely deliver fuel. Some kits include injectors, but verify before purchase.
Are these turbo kits street legal?
Most turbo kits are not CARB approved and may not pass emissions in strict states. Check local laws. For off-road or track use only, these kits are fine. Always retain catalytic converters if required.
How difficult is installation of a KA24DE turbo kit?
Installation difficulty varies. Kits like ISR and Megan are designed for home mechanics with basic tools and some fabrication skills. Expect to spend a weekend if experienced. Budget kits may require more modifications. Professional installation is recommended if you lack experience.
Our Verdict
After researching and comparing specs, owner feedback, and safety considerations, our top pick is the ISR Performance KA24DE Turbo Kit for its balance of completeness, durability, and performance. For those seeking premium response and power, the Garrett GT3071R kit is an excellent runner-up, provided you have the budget for it.
