i can't find any info on the passat. like at all. what is the factory psi on a 1.8t?

How much psi can the engine withstand without swapping internals?

And how much psi can the stock fuel injectors withstand?

cuz heres my knowledge of nothing, from what i've seen, (varying upon company) MOST 4cyl 1.8-2.0 that are turbo'd in the late 90's have stock hp between 115hp-135hp (no psi). what is the passats hp? i've heard 150hp, 178hp, 147hp, can someone clear that up for me?

thanks!
