lol ive heard its a t28, t25 with antoher housing, a t25 bb late model from a 300zx........

Which is it.....

[neverlift]

well it is a t3 turbine inlet with a strange 6 bolt outlet with the flapper, looks like a ceramic turbine wheel, the center looks like a bb unit but that isnt my area of knowledge...the compressor housing has a standard coupler inlet and a 3 bolt outlet that curves..., the comp wheel is nice sized, in comparison to the other t3's I have laying around it is fairly large, the turbs I have here are a saab t3 and a z31 t3,as well as an airsearch t3

Hmmmmmmmm...... damnit, anyways its gonna feed my stock, not opened drifted ka24e which has never done any whinning about anything, SOHC FTW, hopefully at low boost (10psi? from this turbo?) ill get fun, drift, and also a year of life from my engine xD Hope so

i have three of these exact turbos in my garage as we speak this is what i know...t3 flange, t28, 6 bolt output will require stock outlet pipe or ssac or top fuel dumptube, stock atcuator is set for 10 psi, ceramic wheel(do not boost past 14psi at the very most), and it is a ball bearing center.

Dank uuuuuuu

RB20/25 don't have T28's...if it's a T3 flange, then its a T3. That looks like A rb20 turbo.

[neverlift]

I think it gets reffered to as a t28 is its size on the hot side, it is tiny however the compressor wheel is pretty big compares to all my t3's

[WDRacing]

It's a .48AR T3 hotside...

Your best bet is to take the RB20 turbo, remove the compressor housing and wheel, install a TO4E housing and wheel and rock 20lbs of boost. This combo gives you a ceramic ball bearing center cartridge, super light exhaust wheel and the ability to flow a bunch of air. Basically perfect...only downside is that the the exhaust wheel might unass itself at 20psi. I ran 15psi daily and 20psi while racing. I never had one break on me, but it HAS happened.

if you have doen the to4e housing and wheel, will any wheel and housing do? were do you suggest getting these wheels and housings? cause like i said i got threee of these and well if they do disinegrate at 20 then ill just flip flop to another one?

[neverlift]

what are the stock cold sied specs wd? I know for a fact the compressor wheel is larger than all 3 t3's I have

[WDRacing]

Dunno homie

As for where you get a new compressor, get a cheap unit from Ebay or any whole sale place that sell parts and pieces.

[rennbahnmeister]

ever find out? thats a down pipe bolt pattern I've never seen.

[Lopin18]

Its THE ONE, the Choosen Ka-T Legendary Turbine. The one who will win the Sr vs Ka war at long last.

>:P i suspect its just as it was said a T3 Rb20 turbine, since all engines that come to the dom rep are junker engines from japan i prolly got a Rb20 stock turbine that is less common or something.....
