Thanks bandwagn!

I'll look into the options.

I'm mostly concerned with the engines N54 vs N55. I've been reading up and it looks like I can do a lot to the N54 horsepower wise, upgrading turbos, etc. But I've also been told that the N54 stock has some issues:
* waste gate rattle --> have to replace both turbos (~ $3-4k)
* valve cover gasket --> 16-20hrs work + parts (~$3k)

I've been told the N55 doesn't have those issues and was wondering if anyone on here has had issues with the N54?

Thanks,
GT
