Looking for IHI RHB5 Maps.
 

Guys despratelly looking for any and all info I can lay my hands on for a IHI RHB 5 VI34 Turbo. In fact any IHI turbo. If you have something please mail it in to rdchinoy@gmail.com

The story so far. First we hooked up a VI34 and the blades wouldnt even start to spin till we hit 3500 RPM. And by 6000 RPM it would just about start to make 1 PSI.

Hit the Junk yards and found some Turbos with the same IHI RFB5 number but the VI number was diffirent whats the deal with the VI / VF numbers.

We found VI13, VI22, VI24 turbos. WIth the VI 13 having the smallest AR and the VI24 having the largest AR. The AR number on my VI34 was 25. On the VI22 it was 12. So picked up only the Exhaust housing from the VI 24 as it was half the size of the VI34. All the turbos we found where off disel engines and only oil cooled. With no ball bearing.
THe bolt patern was the same but the blades where too large. So we machines the Exhaust housing till the blades fited.
Bolted it up together. Didnt know if it would work. Cause the compresor side was still huge. The exhaust blades where still huge.
Hook it up 800 RPM no movement. 1000 RPM fan starts to move. Take the car for a spin. By 2000 RPM the gauges is showing 2 PSI and then it just shoots to 10 PSI by 3500 RPM and the wate gate opens. Ive hooked up the waste gate to vent to open air so we can hear when it opens.
Know how bad most of my projects go. I cant belive the stupid thing is working so well. There must be a catch.
Please help with any info on IHI.

Id buy the turbo calculator but a mate says not much info on IHI there.
Have scaned the IHI site not much info.

Whats the deal with the VI / VF numbering.
Whats the danger of runing such a blotched hybrid monster.

Thats the same link I get every time I ask the question.
There is no mention of the dozens of types of IHI RFB5 turbo types made.
THe diffirence between the VI and VF series and the diffirent a/r ratios.
