I am building a lightweight sports car from scratch (1500lbs) and I am not sure if I want to use a Miata 1.6 rear end or a Subaru R160 rear end. I have some questions and the R160:

 

• How much does it weigh?
  
• How long is the pinion from the axle centreline to the pinion flange?
  
• Can it easily handle 210 ft-lbs of torque?
  

 

 

If anybody has other recommendations for a light weight, IRS differential, I would appreciate hearing about it.

 

thanks

I shipped one.....and it's about 40 lbs or so. I don't remember exacts, but I think it's around that ball park...give or take 10 lbs.

 

Yeah it can easily handle 210 ft-lbs of torque.

 

If you don't get an anser regarding the pinion, I can try and look at the fsm's when I get back in town

Requested length measurement is approximately 15.75 inches (+/- .125 inch). I don't have a scale so I can't give you a weight. Mine happens to be a Datsun R160. An option for you might be an R180 or R200 from Datsun/Nissans. Same measure/mounting as the R160, just a larger pumpkin area and a little more weight. The R180's are common on Datsun Z's.

Thanks for the info.

FYI - it weighs 45 lbs with no inner CVs. Distance from output centre to pinion face is 400mm

The pinion is 14.25" from end to end.

It is 16" from the threaded end to the center of the axle.

Sorry, missed the "canuckland" and your need for metricality.

 

Let's see... 400mm = 15.650in

 

I guess my parallaxed measurement was a little out of specified tolerance.

 

*edit - Wait a minute... lbs... mm.. mixed measurements? Is your proximity to the the US of A confusing your measurements? 20.45Kg - end edit*
