dont do it, the .48 a/r negates the whole big turbo, 60 trim is better for flow not pressure (lower psi with more cfm), so you will get more back pressure and hotter temps with a 48 turbine that has a compressor designed for low psi and cooler temps
sounds like surge city to me
GET A PROPERLY SIZED TURBO
