The following is a list of specs on the Mitsubishi Turbos. Some are old parts no longer available.
TDO4-9B-6CM2 265 CFM TDO5H-14G-8CM2 465 CFM
TDO5-12A-8CM2 320 CFM TDO5H-16G-7CM2 505 CFM
TDO4-13G-5CM2 360 CFM TDO5H-16G-10CM2 505 CFM
TEO4-13C-6CM2 360 CFM TDO6-17C-8CM2 550 CFM
TDO4L-13G-6CM2 360 CFM TDO6H-20G-14CM2 650 CFM
TDO4L-15C-8.5CM2 390 CFM TDO7S-25G-17CM2 850 CFM
TDO5H-14B-6CM2 405 CFM TFO8L-30V-18CM2 1200 CFM
The above specs are measured at 15psi compressor air flow. I didn't get into turbine flow or actuator settings because of the detail and length of explanation. There's more, but I don't have all the specs. I'll tell you what I know. I'm not including any more of the small TCO,TDO, or TEO4 units because they don't apply to our cars. Nor do they have any relevance to the point being made here.
TDO6-11A-8CM2 TDO6H-18G-12CM2 TDO8-22B-28CM2
TDO6-17A-12CM2 TDO6H-19C-12CM2 TDO8-22D-8CM2
TCO6-17B-12CM2 TDO7-22A-17CM2 TDO8-22D-28CM2
TDO6-17C-8CM2 TDO7S-23A-13CM2 TD13L-47B-47CM2
OK! That's enough, I couldn't find the combination which integrated the elusive -23G- compressor wheel. I called Mitsubishi to inquire about this so called -23G- wheel, they had no record of ever producing anything called ~-23G-. I was advised of the possibility someone may have cut down a -25G- wheel and called it a -23G-. All of the above are about 50% of the combinations available over the last 5 years. Many have been discontinued, most others are for trucks. I put them in here to let you all know what is or what was available. Hope This Helps...

What is the meaning of 14B, 16G, 20G?
The turbo that is OEM on the 5-speed is a Mitsubisho TD05H with a 14B turbine wheel (on the compressor side) and another (I don't know the name/number) and a 060 housing. What the "16G" turbo has is several things. The 16G refers to the compressor wheel. What happens is there are several TD05 housings (compressor) which can accomodate different wheel sizes. There are also two (!) 16G wheels, a large and small. The large 16G was shipped until around Jan 95 and the small 16G have been around for some time. Most likely the 16G you will find will be the small 16G (although the 7cm housing is still readily available).
The other difference is that the turbo has a larger exhaust side housing, hence the 070 or 7 centimeter housing. The wheel in the exhaust side is the same but it is clipped.
Another option is the 20G wheel, but a true 20G wheel will ONLY fit into a TD06 housing, no matter what anyone says as the wheel is physically too large to fit into a TD05 housing (I know because I have a TD06 compressor in my car and the wheel is REALLY big). The hybrid 20G most DSMs run is a 7cm 16G turbo with a 20G compressor wheel and housing.
But in Mitsubishi terms, the larger the number in the 13G, 16G, etc line the larger the compressor wheel and hence more air can be moved. So which turbo has the 16G wheel? The standard upgrade/heavy industry/Stage I, etc are all the same and is the next step up to the stock turbo, and offers a really nice unit for the price as other options can become costly.
