I have just found your website after browsing the net.
I found the Carrera to GT3 conversion story very interesting.
I had a new engine rebuilt by Porsche Belfast in 2014 at 50000
miles. (All done under extended warranty)
My new engine has been running for 30,000 miles and now has
a little rubbing in cylinder 1. Oil consumption is still normal and
exhaust tips clean.
I would be very keen to hear your thoughts on upgrade options.
