My car had a bit of metal go through my turbo, i am now looking at replacing the compressor wheel, now the turbo is a IHI RHB6, i have spoken to several places and i am under the belief that i basically won't get one, now i am looking at putting a garrett wheel in it's place and getting the compressor housing machine to fit it, my current wheel had a 59mm base, 46mm blade tip, and has 10 blades that are 20mm tall.

Basically i want to know, what effect it will have if i get one that has more/less blades, is taller or shorter, etc.

Also be concerned with changing the pitch of the blades coz i think it changes your spool-up time time and changes your exhaust flow, i think that the steeper the pitch (more perpendicular to the wheel) the more power/ exhaust flow it gives you but the smaller the pitch (smaller angle to the wheel) the faster it spools up and the harder it is for for the gases to "escape" the blades resulting in less power... sounds like it would happen but i could be wrong, am i?

Not quite shure about the other ways but i think more blades = faster revs of wheel due to the gases hiting more blades more often and the shorter the blades the more exhaust flow due to the gas can get out of the blades quicker but the longer blades leaves the gases traped longer using more pressure of the gases cooling down against the blade resulting in more of a push aginst them, but once again i could be wrong and it sounds confusing so it musnt be right?

Feel free to tell me i am wrong coz i also want to learn?

Not necessarily, I mean it had to have some sort of effect like your saying, but i think you talking about the turbine wheel not the compressor wheel?
