i've been looking through the posts, and you've praised bored and sleeved TB's rather than simply "ported" - yet you recommend the TDL (ported) over the Blau, which looks like it's bored and sleeved (but costs more). is that worth the extra $? and no, i don't have my own machine press so i can't do it myself. and yes, i do realize this is a beaten-to-death issue. i just need some clarification, b/c i don't know much about these cars...yet. thanks!

My reasoning is simple, BLAU is too expensive.

You should call Joe Hoppen MotorSports for TB work
as they perform the work, and as I was last informed, charge less than Blau or TDL! ;O)

The "bored" TB, is opened up more than the ported, my reason for getting a bored TB over a ported.<ul><li><a href="http://www.audiworld.com/tech/eng13.shtml">http://www.audiworld.com/tech/eng13.shtml</a</li></ul>
