How to get 300HP from 525i ????

[jjdickm]

I'd rather have a lighter 525i turbo with 300hp than a heavier 540i with 300hp. although the 540 is a very sweet car. I've seen 1997 e39 540 going for 8 grand locally. good luck.

I thought about it.. and I'm staying with my 525i.
I took it to mechanic and he was very amazed how the car clean is.
Not a single oil drop anywhere... bottom is like new. It's a CA car from one owner....
I more rather stay with it then buy a car with more miles and rust.. and unknown history. I already found a manual donor that I'm going to use so I'll have other parts also.

The main thing is how to get more power......!!!!!!!
I was thinking Turbo+racing pistons+headers and some other stuff..., but my knowledge is not great in technical side of it.... that's why I asked for help and ideas

Listen to the advice of the people here that are knowledgeable in these things (not necessarily me). You're going to pay through the nose to have this stuff done and end up with a fast car worth less than it is now. Why not just buy a fast car that holds it's value because it's unmodified and spend less doing it?

Ask JonK to build an engine for you with one of the turbos he has

As the author above mentioned, lots of the guys here give very sound advice and have hands on experience on the cars.
