Yeah but if you plan to push n/a-t further then you have to take the head off to fit a tt headgasket, or take it completely apart for tt pistons, a standard tt lump can be pushed futher without that work. Most n/a-t projects ive seen are shooting for the 350-400hp mark, with is pretty much bpu on a stock tt, i dont think n/a-t would be so popular if tt engines where more readily available, and i'd imagine a well spec'd n/a-t conversion wont be a lot cheaper than a tt conversion. But like you said, each to their own, its great to see a bit more variety on the forum
