Any living proof here of an SOHC Turboed engine? :D
SOHC, DOHC, OHV... none of that will prevent you from turbocharging an engine.

What matters is the exact engine model you will be turbocharging. There are some engines that are so well-built, you can more than double the power with a turbo. There are others whose internals are so weak that a mere 50 hp extra can cause failure within a year or two of the installation.

(reliability also depends on how good your tuner and installer are, and how conscientious you are with maintenance).
