n46 is a total wreck of an engine
worst piece of garbage known to man

go for n52, and after buying , pls send to workshop and ask them to check your vanos bolts if they're ok or not.

some n52s have vanos bolt issue, the bolt head putus and fall down into the engine down into the sump. totally fuck up the engine, so better invest in that few hundred bucks have it checked

pretty sure geforce88 got do vanos bolt replacement before on n52s
