1984-1989 Non-turbos came with the FS5W71C transmission. Proven to be very strong in stock form when not abused.

Z32 5 speed RS5R30A has been adapted with FS5R30A bellhousing and custom driveshaft. Internally they are almost identical.

Use a short shifter for a Ford Non-World Class T5.
Examples would be B&M 45050 and 45070 or BBK's T5 shifter.

FS5W71C
1984-1989 Non-Turbos
Use Short Shifter for 71C transmission in S13 240sx.
Examples would be B&M 45088 or OBX SSK8999 (Commonly available on Ebay)

FS5R30A
1987-1989 Turbos
Rumor has it the OBX S13 shifter (FS5W71C transmission) can be adapted to work.
Example is OBX SSK8999 from Ebay

Performance Aluminum driveshafts are available on a special order basis from MSA. If they are anywhere near the prices for other Z cars, they will be very expensive.

Any good driveline shop can take your stock pieces and build you a shaft that will hold gobs of torque and have rebuildable u-joints. Expect to pay several hundred dollars for this.
