is it possible to get blow off vaves for an 03 Lancer ES with automatic tansmission. is it a good idea?

you need a turbo before you get a BOV and BOV's come universal so yea...

what would be the best turbo for the least amount of money for my 03 lancer ES

why do you want a BOV? DO you have any idea what your getting into or what you want? I suggest you research abit more befor doing anything! Now you have an '03 lancer, so it will still have warranty, and if you put a turbo on this car you will void your warranty, just another thing to think about!

You sound like you just want the sound and not the performance aspect (Turbo) associated with it. I think you're interested in the noise for the wrong reasons...

If you are interested in the noice aspect of things, then why not record the sound and play it over your stereo! :)

You could probably get your local turbo shop to make you a custom one for cheaper than a bolt on setup like the ones by RRM

So you want a turbo just so you can have a BOV?
