What you are being told is correct. The 74 and 78 911 chassis both require a "short bell housing" configuration if you don't cut the torsion tube.

It is not until the 1986.5- 911 Carrera with the G50.00/01 "Long Bell Housing" trans was used in the updated chassis. The later Carrera chassis included a revised torsion tube assembly giving clearance for the the deep bell housing 5 speed G50.

The 911 Turbo / 930 also had a deep bell housing from 1978-1988 with the use of the 930 4 speed. The turbo chassis is about an inch longer but still too short for the 5 speed G50.

Since you are installing a 993 Turbo engine than I would suggest a (1987-1989) 911 Carrera, G50.01 Transaxle and then have it professionally made shorter. You will have to get the bell housing and main-shaft machined.

The other options are to us a 930 4 speed or cut clearance or replace the torsion tube section. Sounds like a fun project!
