Ok guys... We all know that the 4.2 V8 swap is doable, there may be some blood sweat and tears, but it can be done. But what about the 4.2TT...? Like, can it PHYSICALLY fit? Just think about it, nearly 450 HP and over 400 torques, in a B5?! I mean, I have no intention, whatsoever to do it, just thought it'd be fun to throw the idea around.

 

In fact, this has been done.
