Mitsubishi Turbocharger Guide

[C89ZX7R]

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.

who wrote this? Needs some better notes. Who's hans racecraft...is that the guy from tokyo drift?!

A real guide would include the numbers stamped to teh compressor covers of the most common turbos, so people can wise up and realize that you can tell the difference between a 14b and a big16g w/o removing anything.

Decent write up, but

^^^This.


Also, I'm not sure the "Super" 16G ever came with a 7cm exhaust housing. My old one had a 10cm^2 housing, that was a Hahn Racecraft thing, along with their Super 20G, those are kind of bastard turbos.

You guys don't remember Hahn? They were/are an outfit out of Chi-town that used to make a bunch of stuff for DSM's. Their turbos were off the shelf Mitsu parts in strange configurations that needed a spacer and an adapter plate for the exhaust manifold since very few people were using an aftermarket one at the time. Their better products were a huge sidemount IC, and an integrated 02 housing/downpipe that was a really nice piece. I had one on my last 3" system and loved it. They were pretty big in the day.

Hahn is a little bit older school. They were the home of the "super" turbos, that never really seemed to perform all that super... Super laggy maybe. But their turbo kit for the NA guys seemed to be decent for that time.

Not everybody is as old as us, and has been in this game for as long either. Back in the dizzle, Hahn, Extreme, Road Race were the big names. Then the others popped up, Buschur, Turbo Trix, Alamo, etc.. Then after all those, the names people know nowadays took the reigns. Been a long time, and been a million DSM shops over the years. (I'm sure I'm forgetting some of the shops, but the mid '90's was a long time ago)

[tehehodi]

I remember buschur and hahn racecraft from the late 90's and early 2k's. I'm 22?

[turbotalon1g]

I think he was just making fun of Han's not Hahns.

At least i hope not.

[goodhart]

You guys, there is two different hahn's. There is HAN'S Racecraft, and HAHN Racecraft. See my last post for the links

Holy crap you guy's need to get off those horses! I may not be as much of an OG as some of you, but I've been around long enough to know who the hell Hahn is. Please note this pic of MY dog turbo, back when he was about 3 months old:


More cute puppy pics with **zzomg** my old Hahn Super20g! LOL!

Good god I'm glad at least one person got my joke!

Reading owns mitsustyle

[Speedfreak]

No high horse, time and age happen, and things evolve. Someone stating a fact that we've been into dsm's for 17 years is just a fact. The market was very different back then and Steve was just feeling a bit old when someone apparently didn't recognize a name that was known in the market not that long ago. I understood Scheides was making a joke of some sort, just didn't know what it was.. I guess that would be the generation gap.

My instant thoughts on a "Mitsubishi Turbo Guide" post was.. Isn't this a bit outdated and short sighted? Who the F still runs this stuff? Thus the thread is irrelevant. So then figured I'd just comment on Steve's comment.

If I recall correctly, didn't Barton run a Hahn turbo on his GST for years?

It's probably the same one that was on my car, Schiedes car, and Goodharts car.

Yup, I bought it from one of the Hort guys, who got it from Barton, who got it from shane (IIRC). Then I sold the car to a guy in iowa, who sold it to a guy in WI, then goodhart got his grubby mits on it
