Can you use a Borg Warner T5 5 speed from a 300zx in a early model 1971 240Z?

I have searched but have found any info saying what differences are between the 81-83 Borg Warner T5 and the ones from 300zx's.

Is it doable?

I have read the zgarage procedure and it doesn't mention the later versions of the bwt5.

You should go do a search at hybridz.org. It has been done, but it's not a bolt in procedure. You need an adapter and some machining done to your bell-housing if I recall correctly.

SOmebody (probably from HybridZ) had Aluminum Adaptors for $390 or so on ebay a while back...then there is the shifter to deal with...
