My knowledge on boosting engines isn't amazing, but I'm assuming if you have a boost controller, you also have some sort of on-board computer and fuel injection kit to dial in the boost and change the tune not to blow the engine. How do you do that with a carbureted system?
I know not much about carb'd turbo system so can't say. One would assume that for a given boost level the engine would fed the proper fuel and spark advance.
I offer no opinion on DIY turbo systems aside from I'd advise against one unless you had some fabricating skills and knew a bit about tuning forced induction.
Otherwise it could get real expensive real fast.
