Hi there.
I just bought a BMW e31 CSI and was wondering how I could get more power.
What about dry sump?

Wow where on earth did you find one of those? That must of cost a few bucks.. You cant do to much to them unless you have unlimited funds........like tens of thousands of dollars. Twin turbos is the best bang for your buck. One of the members here has a dry sump setup. I think its about $3500.00. Kit Central member Cribbj is the guy and here is his friends contact info for the sump. Bill Dailey @ Dailey Engineering

The question is that will I be able to mount th dry sump and is it worth it on the 850csi.
The engine is a beast so far and sounds amazing.

A dry sump really won't add any power. It is used mostly to prevent oil starvation under high G loads.

Turbos are the easiest and get the most power

It takes horsepower to make more horsepower. If you are lacking in the horsepower range than it wouldnt be benificial. Superchargers are belt driven unlike a turbo which is driven by the exhaust. Here take a look at this......

That will only take you so far with these engines, the exhaust port on the head is horrible and nothing short of making a new head will change that. The least expensive way around that is to go with forced induction. You can change the induction TB's and ITB's but you wont get the gains that you want (I dont believe).
Henry has a more aggressive cam that uses the M70 head and the M73 rollers, but I dont know how much it adds.

Here is the real question, what are you looking for? 4, 5, 600hp????

If that is your goal, FI is the only way 4-5k and you are there

only 4-5k?
There is a kit for the e31 and is around 9k and thats the cheapes way I have been told.
I would be happy with 500-550 hp Very Happy
On the other hand I am afraid of the s70 engine. Maybe it would be just better to go with simple m70 and a FI.

Are you putting this into a E31?

The 4-5k is for the components and you doing the work, if you want a kit then 9k it is
