Description

Overview

The Tomioka Racing TR-TM1004 Sigma Turbo is a bolt-on turbo upgrade engineered for the Mitsubishi Lancer Evolution X (4B11T). It’s built for enthusiasts who want a stronger mid-to-top-end powerband, higher airflow capacity, and boost stability—without the complexity of custom fabrication.

Why Upgrade to the Sigma Turbo (TR-TM1004)

  • 100% bolt-on fitment for the Evo X turbo location and factory-style install
  • 3” inlet supports increased airflow and power headroom
  • Ported & polished turbine housing improves exhaust flow efficiency
  • 1.5 bar / 21 psi actuator for strong boost control on performance tunes
  • Mid-to-high powerband focus for street pulls and track use

Power Notes 

The “up to ~550HP” figure is power potential, not a guarantee. Final output depends heavily on supporting mods (fueling, intercooler, intake, exhaust), fuel quality (pump vs ethanol blends), tuning strategy, and overall engine condition. A proper tune is required.

  • Compressor Wheel: 61.4mm inducer / 82mm exducer

FAQs

Q: Is this turbo truly bolt-on for Evo X?
A: Yes—TR-TM1004 is designed as a bolt-on upgrade in the factory turbo location. You still need proper install steps, leak checks, and tuning.

Q: Do I need a tune?
A: 100% yes. Do not install and drive hard without tuning.

Q: What does “up to ~550HP” mean?
A: That’s the turbo’s potential with the right supporting mods (fueling, intercooler, intake/exhaust) and an aggressive, safe tune. Your results will vary.

Q: What supporting mods do you recommend first?
A: Tune + intercooler + intake/inlet + fueling (if you’re pushing power) + downpipe/exhaust.

Q: Journal bearing vs ball bearing—should I worry?
A: Journal bearing is proven and cost-effective. What matters most is correct oil supply/return, heat management, and tuning.
