So I know this is my first post but heck, you've gotta start somewhere. I've got myself a nice little A3 1.8t Quattro (180). And it has a fairly major oil leak coming from the turbo and leaking down the boost pipe to the smic. I was just wondering whether or not it's possible to have a straight swap from the k03 turbo to the k04 (as found in the s3 and tt 225). Would it be a simple job of swapping them over or would it require different manifold/oil feeds and whatever? Cheers guys, Dave.
