Guest Anonymous Posted August 7, 2000 Share Posted August 7, 2000 What modifications are necessary to swap a 5 speed trans. from a ZX into a 71 Z. Are any R180 differentials available w/ gears higher than 3.54(like a 3.90)? Any LSD? Quote Link to comment Share on other sites More sharing options...

Scottie-GNZ Posted August 10, 2000 Share Posted August 10, 2000 KP, there is one thing you will have to be careful of that Randy did not have to be concerned about. Make sure all the clutch components (plate, disc, t/o bearing, clutch fork and slave cyl) match either the 71 or ZX. You cannot mix and match. If the trans is a 81-83 with the long 5th gear and you want a little more zip on the bottom end, get a ZX R-200 diff with a 3.70 or 3.90 ratio. It is a little more work and cost but the best wake up call for a 240Z. Here is a place to start and maybe someone else can point you to a How-To on swapping in an R-200. http://zhome.com/ZCMnL/tech/GearRatios.html ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
