MHI Part Number
Decoded

MHI uses a model designation system that tells you exactly what is inside the turbo if you know how to read it. Most customers only have part of the story when they search for their unit. Understanding the full designation helps confirm you have the right turbo and lets us identify your unit quickly when you contact us.

TD05H-16G-7cm²
TD05Turbine housing family. Determines physical size of the exhaust side and the mounting flange.
HTurbine wheel style. H is the most common on performance units. S, SH, L, and HR are other variants. HR = twin scroll housing.
16Compressor wheel size identifier. Not directly equal to mm -- it is a MHI internal sizing code. Larger numbers mean larger flow capacity.
GCompressor wheel blade style. G and Gk wheels have alternating high and low blade tips. B, C, and T wheels have uniform tip height. G style is most common on performance units.
7cm²Turbine housing scroll area. Similar to A/R on Garrett turbos. Smaller number = faster spool, more backpressure. Larger = more top end flow. 6cm² is roughly A/R 0.41, 7cm² is A/R 0.49, 8cm² is A/R 0.57.

Common Failure Modes

Why MHI Turbos
Come In

MHI turbos are well-built units. Nearly every failure we see has an external cause -- oil supply, contamination, heat, or a boost issue that put the turbo over its limits. Understanding the root cause is the first step in every rebuild we do.

01
Oil Starvation on Cold Start
The most common root cause we find in MHI turbos, especially on EVO and WRX builds running modified oil systems. The turbo needs oil pressure from the first moment it spins. Worn oil pumps, restrictive aftermarket oil filters, or long oil passages starve the bearing housing on startup before pressure builds. Journal bearing wear and shaft scoring follow. Subaru issued a TSB specifically about replacing the banjo bolt on the oil feed line when installing a new turbo on EJ engines.
02
Oil Contamination and Coking
Extended oil intervals, hot shutdowns after track sessions, and any engine oil consumption issue allow oil to degrade inside the bearing housing. Contaminated oil loses its film strength and accelerates bearing wear. Oil left in a hot turbo after shutdown bakes into carbon deposits that restrict passages on the next start. We see this frequently in dedicated track cars without turbo timers and street cars running extended drain intervals.
03
Compressor Surge Damage
Surge occurs when a turbo is pushed past the left edge of its compressor map -- the compressor stalls and the airflow reverses momentarily. On MHI units this manifests as a distinctive fluttering sound that many owners mistake for normal blow-off valve operation. Repeated surge cycles load the thrust bearing with reverse axial force and can crack compressor wheel blades. Common on TD05 units that are boost-spiking or running on maps that are not tuned for the actual wheel size.
04
Boost Spike and Overspeed
Poorly tuned or malfunctioning boost control causes the turbo to exceed its design shaft speed. At overspeed the compressor and turbine wheels experience forces they are not designed to handle. Blade tip erosion, wheel cracking, and catastrophic failure follow. Particularly common on TD04L units on SRT-4 Neons and PT Cruiser GTs running aggressive tunes without proper boost control. Every wheel is inspected at teardown for overspeed-related damage.
05
Foreign Object Ingestion
Intake tract failure -- a cracked intercooler pipe, a loose clamp, or debris ingested through a poorly filtered intake -- sends material into the compressor wheel at speed. Even small debris at compressor RPM is enough to damage blade tips and create an imbalance that destroys bearings quickly. Compressor housing rub marks and bent or chipped blade tips are the diagnostic fingerprints. The intake system must be inspected and repaired before installing the rebuilt turbo.
06
Seal Failure from Pressure Imbalance
MHI piston rings are gas control rings, not pressure seals. Oil leaks past them when the pressure balance in the system is disrupted -- clogged oil drain, elevated crankcase pressure from blow-by, or a blocked PCV system. The rings do not wear out on their own and cannot be replaced as a standalone fix. We diagnose why the pressure imbalance exists before rebuilding so the new seals do not face the same conditions.
Our Rebuild Process

Every MHI Turbo
Done Right

We have been rebuilding Mitsubishi MHI turbos since 2008. Parts are stocked in-house across the full MHI lineup. TD05 is our most common unit but TD04, TD04L, TD04H, TD06, TD07, and TD08 components are all on the shelf. No waiting on parts orders regardless of which series you send. All work including VSR balancing is done in-house at our Dade City shop.


Every job is tracked in our repair management system from intake through shipment with photos at teardown and completion. You always know exactly where your turbo is in the process.

01
Teardown and Root Cause Inspection
Full disassembly and photography on arrival. Root cause identified before any parts are ordered. We distinguish between bearing failure, oil starvation, surge damage, and overspeed so the rebuilt turbo does not fail the same way.
02
Bearing Replacement
Journal bearings, thrust bearing, and thrust washer replaced. Bearing components stocked in-house across all MHI series. TD05 is our highest-volume unit but TD04, TD06, TD07, and TD08 parts are all on hand. CHRA cleaned and oil passages inspected for restriction and coking.
03
Wheel Inspection and Piston Ring Replacement
Compressor and turbine wheels inspected for tip damage, erosion, and overspeed indicators. All piston rings replaced. Seal plates and o-rings inspected and replaced as needed.
04
In-House VSR Balancing
Every rebuilt CHRA dynamically balanced in-house above OEM specification before final assembly. Not sent out.
05
Final Assembly and Inspection
Housings cleaned and inspected. Shaft play verified within tolerance. Turbo photographed and packaged for return shipment.
Common Questions

Frequently Asked

We stock rebuild components across the entire MHI lineup -- TD04 through TD08. TD05 is our highest-volume unit but no series goes on hold waiting for a parts order. Typical turnaround on any MHI unit that does not need wheel replacement is 5 to 7 business days from arrival. TD05 often runs closer to the shorter end of that range given the volume we see. If wheel replacement or additional parts are needed we contact you before proceeding with an updated timeline.
The TD05HR has a twin scroll turbine housing. The standard TD05H uses a single volute. The twin scroll design in the HR separates exhaust pulses from alternating cylinder pairs, which improves exhaust pulse energy at low RPM and speeds spool. The HR was used as OEM equipment on the Lancer Evolution IV through VIII. All TD05, TD05H, and TD05HR units share the 49178-prefix part numbers. The twin scroll housing is visible externally -- it has two separate exhaust inlets rather than a single inlet on the standard unit.
Yes, but it requires a matching manifold change. The twin scroll housing on the HR requires a twin scroll exhaust manifold with separate ports for each housing inlet. If you swap to a single scroll TD05H housing you need a single scroll manifold to go with it. Both will bolt to the same CHRA cartridge. Many EVO owners swap to a single scroll setup for simplicity or to run larger aftermarket turbos that are not available in twin scroll configurations. We rebuild both configurations.
Subaru TSB 02-103-07 specifically addresses the oil feed banjo bolt on EJ engines. The banjo bolt connecting the turbo oil feed line at the cylinder head can develop a restriction over time, reducing oil flow to the turbo on startup. Subaru recommends replacing this bolt whenever the turbo is replaced. It is one of the most overlooked installation steps and a common cause of rebuilt turbo failure on EJ engines. Always replace this bolt, the copper crush washers, and the oil feed line itself when installing a rebuilt turbo.
Drain any residual oil from the inlet and outlet ports before packaging. Plug the ports to prevent contamination during transit. Double-box the unit with foam or bubble wrap on all sides.
