E30 325i - too slow! Help !

["Rob" <motor@xxxxxxxxxxxxx>]

    Okay E30 experts ,I need to make my car faster ,but my budget won't
allow for an M50 conversion or a turbo,etc...

It's an '89 325i drivetrain with:
- -Stromung exhaust
- -MSDS header (no cat)
- -Jim C. chip (genuine)
- -K&N - in box
- -3.91 LS diff

 What else can I do to speed up my winter machine??

Thanks
Rob
