Do you have a picture of the compressor side opening?
You will need to know what size the compressor is - 45, 50, 55, or 60 trim.
One needs to measure the compressor inducer size.

You have the turbine size of .48, good for 300 hp (maybe more in some cases.)
The compressor side will tell you the maximum HP capable.
One could have a 45 trim compressor with the .48 housing. This would be laggy and maybe support 230 hp.
