Supercharge Supercharge Supercharge !!! - BMW Forum

I'm looking at fitting a supercharger to my 325i, so I'm on the hunt for information regarding the logistics of it.

The story so far:

I know I’m going to use a mini Cooper S Supercharger, which can be easily picked up with just delivery mileage on them as lots of people upgrade to a works kit.

My 325i doesn’t have AC so I can change the alternator pulley for one that is used on cars with AC, which will hive me the rotation point.

From this point on is where it gets a little sketchy, I know I’m going to have some compression issues to deal with, and I really want to avoid detonation. I understand that there are some engine management systems that could help with the majority of these issues.

So this is where you guys come in with your infinite wisdom, great ideas or just some moral support.

Agreed. Don't cut corners when going FI, you'll end up blowing the motor. It will end up being more expensive than if you hadn't cut corners

If you're good at making things you shouldn't have much problem.

You'll have to make up a custom braket for the sc to mount to. You might be able to use a turbo intercooler for the piping to the TB but from SC to IC you'll need to make something.

Ussually the sc on an e36 is mounted on the intake manifold side so stay away for SC intercoolers for the e36.

There's absolutely nothing wrong with being cost effective in FI. The cooper S super charger is only going to crank out max 8 lbs of boost. That's what all the other super chargers are going for with stock internals. Stuff is going to wear more quickly but there's no need to buy a pre made kit for 5k when you can put together your own for 3k.
