Does anyone know what the upper capabilities of this turbo are? Going to get my Spec C Type RA remapped. I'm happy that even a 50bhp increase is of little stress to the JDM lump in general, but I'm not sure on the capability of the turbo?

 

From what I've gleaned on here, 350-60. 370 if lucky.

David O'Brien (former API proprietor) had an Owens Developments fettled one on his WR Blue JDM Blob STi, and it mapped to around 394bhp and 397lb ft.

I drove it as a courtesy car - it was grin-inducing.
