IMHO, the places you shouldn't go cheap are the MAF, fuel injectors, chip/standalone, tuning.. since those are the things can end up costing you a motor... maybe WG actuator should go in that list too..

another random thought that came to mind.. is that something small like.. say.. the size of the oil feed and return lines, their positioning, and the use of restrictor on the flow (if any).. seems like a really small, random thing.. but its still key to get it right or else it might cost you a few turbos and a lot of headache..

could be worth it to buy a used hardware kit off someone and add on your own MAF/chip/injectors/tuning..
