⭐⭐⭐⭐⭐ James Carter - Mitsubishi Galant VR4 Owner
"Installed the Twin Turbo TD025L (Pro Model) last May and the difference is night and day. My VR4 now pulls strong from 2,500 RPM with zero lag—thanks to that twin-scroll design. The nickel-based turbine wheel runs cool even during back-to-back mountain runs. Power feels like a 3.0L V6 now."Purchase Date: May 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Alex Rivera - Lead Mechanic, Apex Motorsports
"We’ve installed three of these TD025L units in customer Galant VR4s, all with MD181384 engines. Fitment is spot-on thanks to the OEM-matched flanges. One client pushed 1.4 bar with custom tuning—no signs of stress after 6,000 miles. The heat resistance on the Pro Model is legit."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐☆ Derek Simmons - Off-Road Adventurer
"Running the Advanced Model on my trail-built VR4. It’s been through desert heat, mud bogs, and high-elevation climbs. The turbo holds boost consistently, even under load. Only reason it’s not 5 stars is the need for professional installation—hoses needed slight re-routing in my lifted setup."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Linda Park - Fleet Operations, Summit Logistics
"We retrofitted two delivery trucks with industrial diesel engines using the TD025L’s customization options. Boost pressure set to 1.1 bar for consistent hill climbing. After 4,000 operating hours, no turbine degradation. The 1,200-hour durability rating isn’t marketing fluff."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Marcus Lee - Amateur Circuit Racer
"I was skeptical about turbo reliability on track, but this thing is bulletproof. Spooled at 2,800 RPM every lap, even after 10 consecutive hot laps. The lightweight Pro Model housing helped reduce turbo lag dramatically. My lap times dropped by 1.3 seconds average."Purchase Date: April 2025 | Usage Period: 3 months
Average Rating: 4.9/5 ⭐ (89 Reviews)
Dr. Elena Vasquez - Turbocharger Systems Engineer
"The TD025L stands out with its twin-scroll housing and Inconel 718 turbine wheel—materials typically seen in motorsport-grade units. The 20% improvement in exhaust efficiency and 15% reduction in spool lag are measurable advantages. For Mitsubishi 6A12 platforms, this is currently the most balanced performance upgrade on the market."
Tomohiro Sato - VR4 Performance Tuner (15+ years)
"After testing multiple turbo options, the TD025L delivers the most consistent gains without sacrificing reliability. Its compatibility with MD181384 is flawless, and the boost adjustability makes it ideal for both street and track builds. I now recommend it as the default upgrade for all my clients."

"Used on a track-prepped Galant VR4. Held 1.2 bar boost through long straights and rapid gear changes. No oil leaks, no heat soak. The precision-balanced compressor wheel really does reduce lag. This is a serious performance part."

"Performance is outstanding—30% more punch, just like advertised. Only challenge was aligning the exhaust manifold due to tight clearance. A little patience and it fit. Would love a detailed install video next time."
