Jamie,
Trans is the stock 80 915. Take a look at what they build. Here is a copy of the link Excellence did in 2003:

Also here is a link to the tour of the shop.
INTERMECCANICA - FACTORY TOUR There are some very cool pictures of the jig welded 911 tube frame used. What I did was buy a ratty 1980 Targa with 115K miles for all the running gear.
Not for the faint of heart price wise but I can't afford a real Speedster and this one will have electric windows, heated seats, upgraded suspension and a 3.0L for fun.
If you think I'll be on the right track keeping the stock CIS cams then that will save me some money. The original ones from the motor are like brand new. I split the cases and the bearings even the intermediate shaft bearings looked like brand new.
Any other thoughts from anyone?
Thanks!
