Just Wondering???

Ok so here is my questoin...
alright im looking to buy a MKIV but for some reason prices on the twin turbo versions have gone up, alot.... I was wondering if i would buy a N/A, would it cost alot to make it a twin turbo, or even put a twin turbo on it, or even a single turbo since i hear ppl et alot more HP with those, that would make it faster than a twin turbo version?

For all the effort and money needed to do the conversion it is better to get the turbo model to start with.

for the transformation you would need... engine(big $), transmission(bigger $), brakes, suspension, clutch.... alot of parts, not to mention the cost of labor.
