I was replying to a question regarding information on the 3.4L conversion when the forum magically reset to an earlier time.
A good thread on an engine conversion can be found here:
http://www.renntech.org/forums/index.php?showtopic=4798&hl=
The quote I got last year for the conversion on a 98 Boxster goes as such:
"Price is usually about $6K for a decent motor, $1500 for reprogramming, $2000-2975 in exhaust and $1500 for installation and conversion parts."
Sadly, I have heard that a 97 Boxster requires a new DMU. For some reason, it can't be programmed for the conversion.
P.S. I was re-reading the renntech thread. My favorite part is when somebody brings up the idea a supercharger with the 3.4L conversion. More power, more power!
