Mitsubishi Turbos:

Mitsubishi uses TD04, TD05, TD06, TD07, TD08...to designates turbo housing.

For example, TD05H-16G 7cm^2 is a turbo with,

TD05 turbine housing with 'H' style turbine wheel. There are S, SH, H... style of turbine wheel/housing.
16G compressor wheel. 16 is the size of the wheel, 1.83 inducer, 2.37 exducer. There is no direct correlation between MHI designation and actual physical size of the compressor wheel. G is the style of wheel (uneven height of blades). C, B, T style wheel's blades have the same height. Blades are equally spaced, but the number and pitch of the blades vary between models.
8cm^2 is referring to exhaust discharge area in the turbine housing. More specifically, it is the smallest cross-sectional area of the scroll, turbine housing. Very similar to Garrett turbo's A/R. The smaller number means faster spool-up but more back pressure at higher rpm. Bigger number means longer spool up but less back pressure, thus more top end power.

Greddy modifies Mitsu turbos. I don't have any published specs for Greddy turbos and i have not taken any time to measure them. It's possible some of turbo’s have different specs from Mitsubishi. Also, both Greddy TD05 and TD06 use 3 bolt turbine flange where as Mitsubishi's uses 4 bolt flanges.

Besides the TD04, TD05, TD06, TD07 and TD08 turbos, Greddy also makes hybrid turbo, T67 is TD07 compressor and TD06 turbine, same turbo as TD06SH-25G. T78 is the compressor of TD08 and turbine of TD07, T88 uses compressor and turbine from TD08.

Garrett Turbos:
Garrett basically has two lines of turbos. The ancient, inefficient T series turbos and the new, modern, ball bearing GT series turbos.

T family has T22, T25, T3, T350, To4B, To4E, TS04, To4R ...These are 50 year old, WWII generation turbos.

The newer line of GT turbos are ball bearing on journal and thrust bearing. The turbine and compressor wheels are improvely aerodynamically to flow more air. GT20, GT22, GT25, GT30, GT35, GT40, GT45, GT50... GT turbos produce slightly more hp then older T series turbos with the same number designation. A GT Garrett turbine wheel wil flow more air than similar sized Greddy turbine wheel. Thus GT turbos are able to boost higher and flow more.
Turbonetics and many domestic makers turbos based on T series turbos. A T3/To4E 60 T .63A/R is a hybrid turbo with T3 turbine, To4E compressor, 60 Trim compressor wheel and .63 A/R turbine housing.

Wheel "trim" refers to the squared ratio of the smaller diameter divided by the larger diameter times 100. Generally, the larger the trim number the more flow the wheel has.

For compressor wheels , larger trim tends to mean slightly lower efficiency.

For "families" of turbine wheels (those with the same inducer diameter), larger trim usually means better flow with less backpressure but longer spool time.

A/R is a ratio of the exhaust discharge area vs the distance from the center of turbine wheel to the center of the cross sectional area. Smaller A/R housing has faster spool up. Bigger A/R housing has less back pressure, more flow for the top end.

The so called "T-series': T60, T61, T66, T70, T72, T76... are T4 turbos as well. The number means the compressor inducer size. ie: T76 means it has 76mm compressor inducer.

TDO4-9A stock turbo on a G32BT 83-86

TDO4-9B Stock turbo on a G32BT 87-88

TDO4-11B Stock turbo on a 4G61T 1989 4cm exhaust housing.

TDO4H-13C Can be found on the Lebaron GTs. Exhaust housing will have to be replaced by your stock exhaust housing and machined to accept the TDO4H exhaust wheel. Lebarons exhaust housing will not bolt onto your stock header/manifold. 330cfm@15psi of boost.

TDO4H-13G DSM Automatics. 360cfm@15psi of boost. 5cm exhaust housing.

TDO4H-15G Upgrade turbo sold in Europe and Japan. 440cfm@15psi of boost. 5cm exhaust housing.

TDO5-12A stock Starion/Conquest turbo1986-1989. 320 cfms@15psi of boost. 8 cm exhaust housing. exhaust housing is not a direct bolt up to a DSM. Cartrideg and compressor could be swapped into a TDO5 DSM exhaust housing if needed in a quick replacement but not recommended.

TDO5-14B Stock DSM turbo here in the USA. 420cfm@15PSi of boost. 6cm exhaust housing. Can upgrade exhaust housing for more midrange to top end using the 7cm exhaust housing.

TDO5-14G Upgrade turbo for the Starions and Conquests. 465cfm@15PSi of boost. Starion and Conquests came stock with 8cm exhaust housings. To use on a DSM you will want to take a 6cm or 7cm exhaust housing from a DSM and install it due to the fact the 8cm exhaust housing uses a different downpipe bolt pattern and shape is different to make installation much harder and require custom fabrication.

TDO5-16G Upgrade for DSM 505cfm@15psi of boost. Looks the same as 14B. 7cm exhaust housing.

TDO5-Super16G 550cfm@15psi of boost Looks the same as 14B. 7cm exhaust housing.

TDO5-16G EVOIII 550cfm@15psi of boost exhaust housing is shapped different 7cm or more. Looks the same as 14B.

TDO5-16G EVOIV-VIII larger compressor housing and dual exhaust scrolls. Some exhaust wheels and shafts are titanium depending on if you are in the USA or not. 550cfm@15PSi of boost. 8.5cm exhaust housing.

TDO5-16G EVO IX Larger compressor housing, larger exhaust housing then previous EVOs, and larger exhaust wheel and it is titanium this year in the USA. 10cm exhaust housing.
