Nissan 90-series transmission was the FS5R90A, a Borg-Warner T-5 in 1982-1983 280ZX Turbo. Often it is replaced by the more common 71C series box which is reportedly just as durable. Now manufactured by TREMEC.

• 1983 came with L28 bellhousing
• 1984-1987 came with VG bellhousing

World Class

The bad crap T5 are the pre-1986 ones, while the WC T5 is the fave budget performance box worldwide for any conversion no matter what engine. The T5 in post-1986 models shift a world away from the earlier horrible contraptions that were the first T5 boxes. Ive driven Falcon utes, panelvans and other post-1986 T5 and they where nice to shift and very reliable while the earlier ones are just plain trash.

* 1985-1996 Chevrolet Camaro (some)

The T5 can be swapped into Datsun 1200 using an A-series automatic bellhousing and an adapter plate. The input shaft is easily removed which helps for shortening to suit A-series spigot bush etc. Use a 5mm adaptor from box to the auto bellhousing, machined input shaft and Ford Escort type clutch to A-series flywheel and Ford hydraulic release bearing.

It's a very modular gearbox and cheap -- close ratio gearsets cost $1095 USD.

GM Camaro World Class T5. Amazingly this strong box -- that usually sits behind monster engines -- only weighs 33kg (about the same weight as the 63A 5-speed).

GM S-10 pickup T5 is the shorty and lighter again by maybe 2-3kg

World-class T5 in shift feel is like the Nissan 71C (S13/S14) gearbox, very sure crisp shifts where you know exactly where the gates are everytime.
