IHI RHB51 turbocharger - Specs?

[a_spec]

He all,
Does anyone here know of, or can link me to, the actual specs of this turbo fitted to the City II?

I can not find the A/R, or the specific sizes of compressor wheels trim A/R and the actual dimensions of the turbine wheel diamiter, A/R or trim. Any help would be great.

Iv got one in parts in my work shop. Tell me what you want mesured and ill mesure it up.

Your a legend. The size of compresser / turbine wheels, see if it has the A/R's listed on it, basically the measurements of what was stated on the first post. Trying to get a base line to compare the size of it to after market turbos.

So for instance, if you look at the specs below:

Id like to compare it in size to modern day Tutbines.

Im assuming that it would be similar in size to a GT12 but that is an asumption based on nothing.

Id like to compare the specs to those above of the GT 12.

Double post.

exhaust turbine is 31mm high 127mm wide.
intake turbine is 38mm high 127mm wide.
Intake side of compressor snail is 101mm in, 90mm out (compressed side)
Exhaust side 76mm in and 101mm out (cant mesure stock wastegate hole since mine bored out)
Turbine shaft is 16mm on the berings.
This is a T2 turbo.
Iv got a T1 turbo aswell and everything was slightly smaller. Im not going to pull it apart again because its just been rebuilt and it was hard enough getting all the seals in correctly the first time.

Absolute legend. Thanks you brother.

What have you measured there? He ideally needs the inducer and exducer diameters of the compressor and turbine, thats the diameter of the fins at the little end and the big end.

For instance, I dont know what you measured on the exhaust side to get 76mm and 101mm but it doesn't sound like anything useful to me (outside measurements of housing?).

[bmgjet]

Inside measurements at the widest part since it tapers.
Mesured it using a protractor and put pins at widest part then mesured the distance between them including pins.

Did same with the the turbines.

Am I meant to measure them at the narrowest part.

Thanks guys. Just want to know if it is comparable to either the GT12 or GT15. What do you think the stock turbo is most comparable to?

Its very simular to the IHI RHB5 VJ11 from mazda B6T engines.

Thanks BMGJET, but if you were looking for a brand new replacement turbo, what would you consider to be the best matching stock turbo?

Search for the holden rodeo turbo thread on here. That looks like the easiest one to swap on.

Or you can rebuild your stock one. Rebuild kits cost $70 to import then a place here in NP installs them for $160 with out re-balance.

Thanks for that bro. Might have to look a little further into it.

I've got a T2 turbo sitting on my bench, Ill measure it when I remember, sometime this week hopefully.
