Are the s5 turbo halfshafts, diff, driveshafts and tranny any stonger then the s4 turbo?

 

well from what ive been told the s5 is one of the best years of the rx7 ever built. and one of the most durable.

 

ya thats what ive been told but do these parts have a difference?

 

No.
And the S5 LSD is actually weaker, in my experiences.

 

i dunno but ive givin my car hell and everything but the motor has held up. lol

 

Uh, No...

The S5 cars have considerably more short cuts taken on production than the S4 or even S3 models.

Things like plastic end links on suspension members that shear, or lame plastic thermostat housings that tend to dissolve at 150K miles, or seat belts that are on a lifetime of the car recall are most certinly not more durable.

 

No.. they are the same, except the tranny which got only minor changes, none of which increased durability.
