IHI RHB-6 rating

Greetings,

I'm a new member here, I have an IHI RHB-6 turbo which I'm going to implant to a B6 engine. Does anyone know what is the maximum horsepower rating for this turbo? If anyone has a compressor map that would be good too. I measured the compressor outer lip diameter is 55mm.

Thanks,
Chairil.

it's huge for a 1.6L, about the size of a TD06? a 55mm comp inducer is BIG.

try to find the turbo spec here: http://www.turbomaster.info/eng/cata...hi&pagina=RHB6

and translate it here: http://www.angelfire.com/extreme4/ma.../mx6/page.html

the turbo itself is good for 592CFM or about 370BHP.

that next step I'd do is determine the turbine A/R and trim to see if you can spool it within reason.
