My 83' 911SC finally saw the light of day...after 7 years rest, with a re-worked 915 w/Proforce clutch/flywheel pakage and a fresh 86' 930 motor, the car has been quite a revelation since putting roughly 3500 miles on it. It's more car right now than I am driver. 'NB' is for a narrow-body, sans the more extended size, weight, and aero drag of the standard 930 set-up.
911 Design in Monclair did the conversion(which was a lot more extensive than I imagined...) and did some fine-tuning/adjusting afterwards pro bono.
Slightly upgraded k-27, no a/c install. Stock US 86 Turbo exhaust, w/baby wastegate muffler.
Wonder if I should junk the K&N that came with the car and go to stock air-filter? 3.3L US
