How to change sound engine of the car?

Hey guys, i was wondering, since we got new keys, how to change soung engine of your car. I would like to try that.
Phat, you will probably answer this question, so bring it on

First of all, you will have to download and test a whole bunch of cars to hear the sound of the engine you would like in your GRF car! So, first go on the hunting session here.
When you find the sound you like, remember the name of the car, open its .zip file, and select all EngineXXXX.wav sounds
(xxxx = Low, Mid, Idle, Fast...)
and just drag them out from the .zip onto desktop or any other folder.
Then open your GC-3 car .zip file, and simply drag the sounds into this zip file.

Then you will just have to re-create a new locator for your car, since those engine sounds could take a shitload of space (some even up to 3-5MB), so you will have to bear in mind that you would have to wait a pretty much more time for others to see your car than you would without the engine sounds.

EDIT:
btw, for Horn applys everything from above

Hm..I'll think about it, since there is a problem with seeing car.
