oh yeah i seen it up close it looks like a nice peace of work, the inlet is enormous and definetly is too big for the stock intake tube.

the inlet looks very nice im trying to figure out what i could adapt to it the thing is much larger than any v turbos inlet im assuming the copmressor is the big 16g. The guy told me it is only good for like 380hp but it is twice as big as my vf23 and that is good for more than 350. He did say however that it can run 30psi yes you heard right 30psi of boost. he must of misunderstood me because if it can handle 30psi it has to be good for more than 380hp.

If it really is a 60-1 compressor in a To4B compressor housing, it is worth quite a bit more than 380hp! On the other hand, it would likley not be spooled anywhere near the quoted 3800rpms

joy......they started making frankensteins for subarus now i dont personally think id put that on my own car. and i wouldnt think for a second that that hotside connected to a 60-1 wheel stuffed in that housing would be spooled @ 3300rpms. it may make positive manifold pressure, but not any significant boost by then. assuming it holds together it could make good power though........not something id wanna drive around on though

It would be nice if they could put an even bigger wheel in there !

I hope you mean a bigger turbine wheel, because a 60-1 compressor wheel is already large enough that you'd have to rev your motor to almost 9 grand to really make full use of its compressor map.

Some serious portwork would help also.

To give you an idea... this Compressor wheel in a DSM with a different turbine is large enough to run low 10s to high 9s.

I would really like to know which turbine wheel is in this housing as there is no "16G turbine wheel" It's likely a 5h or 6h turbine wheel. 16G refers the compressor side of a turbo. In any case if this is a good match of the turbine wheel to the compressor housing you could have a 10 second turbo there.

Please find out more about the size of the turbine side of this piece. That is, indeed, a giant compressor side.

Looks like a P20 IHI turbine side. I am sure it's clipped or modified though. I doubt a stock P20 turbine side has enough room to flow the exhaust gases created by that huge 16g compressor pumping all that air into the engine. What goes in....must come out.....

That's not a 16G compressor, that's a TO4B 60 trim (much bigger). I'd never call a 16G huge

It's actually a 60-1 which IIRC is something different and even larger than a To4B 60 trim.

im going to give them a call tuesday and get the full deal on the turbo, the interesting thing is that i seen at the lime rock car show and the tag said stage 3 i wonder what 1 and 2 are hopefully when i call i will get the specs for whatever turbos they have available. If you go to their website all of their turbos are affordable that their motto.

heres a small pic to give you an idea of what someone would have to make an intake for, the to4b is on the right and below it is a t-78 housing.

How did you guys go, I agree looks promising but what size is the exhaust it could be limited by the size of the exhaust wheel rather than comp side.
pls email me with more when u find it

Here's the straight poop on the TO4B:

All TO4B's have a 2.75" inlet.

This is a TO4B 60trim 60-1. It even looks like one It has a 2.324" inducer diameter and a 3" exducer diameter (a T67 25G uses a 2.381" inducer and a 3.070" exducer, a TO4E 50 trim is a 2.12" inducer and a 3" exducer). That's a damn big wheel. The compressor section is rated at 65lbs/min.

Usually, this is mated to a T4-sized exhaust housing, or potentially, a worked T3 housing.

The TO4B is a workhorse housing, it' been around for ages and a day. It works well, and it's cheap. It is NOT as good as the TO4E housing, which has differences and is the next evolution. It seems to me that they could make this with a TO4E housing just as readily.

Here is the compressor map:


And a pic, note the size of the T4 exhaust housing compared to the piddley thing above:


There is an upgrade for the MKIII supras using this compressor and the Hitachi CT-26 exhaust side. It's rated at approximately 450hp. Here is a pic of the CT26 exhaust side on a normal turbo. The CT26 itself (not the one we are discussing) is a mild upgrade to the stock turbo on an MR2 or Celica All-Trac.


Most MR2 owners consider the 60-1 to be overkill when mated to the CT26 exhaust side...the turbine is the limiting factor, and it's never really operating at its potential. The compressor will flow 25psi with ease.

The turbine wheel size for a CT26 are:
Turbine minor - 1.97"
Turbine major - 2.36"

For a T3 turbine, the base wheel size is:
Turbine minor - 1.898"
Turbine major - 2.319

Stage 2 T3:
Turbine minor - 2.122"
Turbine major - 2.559"

As you can see, the CT26 is kinda like a mild stage 1.5 T3 turbine section. A Stage 2 T3 turbine section is almost the same size as that on a Greddy TD06SH-20G.

Greddy TD06SH-20G:
Turbine minor - 2.177"
Turbine major - 2.559"

Now, this turbo is supposed to have a "16G turbine". There are many varieties of turbines mated to the 16G compressor wheel, including 7, 8 & 10cm^2 turbine sections. In mitsubishi lingo, the TD05 refers to the turbine section, and the 16G refers to the wheel, with the final number (6,7,etc. cm^2) refering to the exhaust housing opening

TD05-16G-10cm^2 turbine:
Turbine minor - 1.930"
Turbine major - 2.200"

An IHI P20 (all I have is the minor, not the major, or the portion within the housing):
Turbine minor - ~1.77" (45mm)

Essentially, get the turbine wheel sizes, both minor and major, and then we can see what this is worth. It is certainly conceivable that they have made a TO4B 60-1/16G-10cm^2 hybrid, which should actually flow pretty well.
take care,
rob

i tried calling them today but no answer. Do you think that its worth a try on my car. if so i am still trying to figure out how to fit the intak tube on. I am thinking of getting a reducer hos connector from turbonetics and just cutting alittle off my stock plastic piece.

I would find out the specs on the exhaust side before you do anything with it, otherwise you are getting into an unknown quantity. This would also require the big injector/fuel pump type mods, I assume you know that, of course .
take care,
rob
