Another interesting question
 

as u may or may not know i have an FD since apr 05 and i have allready lost the tranny (AUTOMATIC), doing a 5 spd conversion my question is how long can the engine/turbos last b4 the innevitable happens 100k 90k my cousins blow at 97k

I would say if it's original engine and turbos, it's highly likely you'll be needing a rebuild. Start planning for it, it could be any day,especially if you drive aggresive.

Wow - so your 'interesting' question is the one that is asked probably more often than any other question in the history of this forum.

Perhaps you should search the next time you have a question.

where it says "24) When does an engine need to be rebuilt? I heard FD engines only last 60k, is this true?".
