Xud's do randomly throw rods in standard form. Bosch 9mm will be fine. Your standard turbo will probably be fine and will make the power, but tuning the engine might cause it to wear slighty sooner than if left alone. So basically full exhaust, or some mods or whatever, if you know a guy with a welder its cheap enough to just make a whole system. Then get your bosch pump on and give it some fuel then see if the turbo needs adjusting. Actually an MBC wouldnt be a bad idea either. (manual boost controller)
Doesnt even own a 306.
