Well since I assume you would be fabbing some stuff up the conversion would be easier for you than a DSM since you don't have lines already for oil pressure, oil drain, coolant...........etc.
We have to modify our existing water and oil lines, get a bigger gasket, 2.5" flanged downpipe....etc.
You just have to make sure your downpipe, water lines, oil lines, oil drain, downpipe flange are all built to match the Mitsu 14B instead of the Garrett because they are slightly different. Also need the bigger 7cm2 manifold-->turbo gasket. The compressor outlet is also slightly different so the I/C pipe needs to match it as well
