Anyone have numbers for FI e34 525 engines?

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.

Maybe someone can just link me to a supercharger manufacturer's site for the e34? I haven't found anything that's not specifically for the 540.

Nevermind...ESS makes a supercharger kit for the e34 m50

6400USD! :(

Thats not bad. I am sponsored by VF engineering. If you want, I can get you a discount on one of their '93 325 kits. But you'd need to do standalone ecu

Also: There is a project I am part of that entails reverse engineering the Bosch 403 ecu, the 402 (non vanos) is another job, but baby steps are in the process. This project is on-going over at bf.c, which is down right now.
