Hey all!

I've got an 01 325i and I'm looking to speed it up a little. I don't want to spend a lot of money and don't want to break my warranty. Any suggestions??

Thx!

 

dont know what to tell ya man bmw shit isnt the cheapist!!

 

I'm looking for more along the lines of tricks right now. It's been a long time since I did this stuff, but we used to flip the tops of our air cleaners over (not good for the intake but it worked), change to hi-flo air filters, change to better plugs, and advance the timing a touch. Stuff like that - maybe enough to pick up 20-25 HP until I get serious.

Does anyone know about stuff like that?

 

um, its a bmw dude, not a honda. you cant neccesarily do that with your car lol...i have a K&N drop in filter and it was worth the money, not too much of a power adder obviously, but definately a noticiable change in throttle response and more torque in the higher rpms for me

 

I think he was using that as an example. flipping air cleaner covers over is a old domestic V8 trick. my dads truck has the air cleaner cover upside down.

get a k&n, play with timing, and make a header back exhaust, keep the stock exhaust handy for trips to the dealer. unless they dont care.

 

Yea, that was what we did 20 years ago when I got my first car. '76 Cutlass Salon, 350 Rocket, 350 TH tranny, and .333 rear end. I built up the bottom half of the motor, went from vacuum to mech. secondaries on the carb, changed out the tranny, and all the rest. Then I learned what part the rear end gearing plays in final drive. LOL!

What do ya mean make a header back exhaust. It sounds like you're talking the piping and not the manifold. Sorry for sounding like a newbie, but things have changed so much I guess that's what I am.
