I was thinking about doing an LS1 swap into my '92 525, but am kind of backing off due to the amount of hassle it would entail.

I'm primarily concerned with acceleration, so was thinking of a supercharger instead of turbo. Does anyone have any hp/torque numbers that the 525 non-vanos is capable of?

Bi-turbo would be best, but I don't plan on spending 10k+ on it so I've decided to just go supercharger instead...if I have to spend that kind of money I'll just go ahead with the LS1 swap (will cost around 8k-9k total).

Any help/advice would be appreciated.
