Good thinking! Carefull with the Garretts, as besides the (even bigger) GT4088R, all the smaller then 40R Garretts are not specifically designed for twin scroll imho.
Also, if your looking at anything smaller then a T4 turbine section/foot print, I wouldn't bother with TS either, but thats just me.
