I have just bought a 1994 300d with the 2.5 turbo. I love the cars and the exceptional longevity of the engine but the power is quite lacking. Is there anything I can do to increase the power in my car? Do know of a good way to upgrade the turbo or any other aftermarket performance products?

There are no aftermarket parts for that engine. Any upgrade parts you want you will have to make or adapt yourself.

Just enjoy it as-is. There is nothing you can do to it that will give you more power without spending a few thousand dollars.

It looks like you have done some work to your car. how did that go. I'm in third year mechanical engineering so I plan on doing some machining and mickey mousing maybee for a larger turbo.

I've put far more money in my car than I like to remember.

The problem is in the injection pump's flow limit. You have about 120HP but your injection pump only has enough overhead to give you about 140hp if you adjust it to it's max. Sending the pump to Myna Diesel Finland for larger elements and their secret tuning will cost around $2500-3000 after dollar-euro conversion.

A larger turbo will also increase turbo lag and really hurt it's daily driving qualities.

EDIT: Never mind about the ratios, I'm not sure what the 1994 used.
