Why is when mentioning upgrading a 6, there are people that want to wipe the 6 and go straight for the V8?
To me, there is nothing wrong with spending a few bucks on a 6, just to liven it up a little, without the expense of upgrading to a 8, just for the hell of it. Geez, the 6cyl car might have some sentimental value, or a case of the better the devil you know, that the one you don't.
Yes, a little off topic, but it seems all to common place when even the words upgrade 6 come to play.
Oh and sorry I can't add too much tech advise in this area
