I am upgrading the turbo on my 1983 Volvo b21ft. What I have in mind is to keep the .63 A/R turbine housing and upgrade to a .60 trim compressor wheel. The compressor housing has a .42 A/R. Would like a larger A/R on the compressor housing also. What size would you recommend. The engine is stock and will run stock boost levels. Manifold have been upgrade to a 90+ exhaust manifold and a B21f intake manifold.

THanks
