The conversion is very easy.
Parts you will need are
Subaru WRX STI R180 diif. Needs to be from 2004 - 2009. Approx $400-$1000 depending on condition and LSD type.
Datsun R180 or R160 pinion flange (tail shafts bolts to this.)
Beta Motor Sports adaptors $500 Link above
Datsun 1600 half shafts (the type that bolt in both ends) Free
RUJ-2028 Uni Joints (optional) $18.35 ex gst from Bearing wholesales Bayswater.
Work Involved.
Car up on stands
Unbolt half shafts remove them from the car
Unbolt tail shaft. Don't remove unless you want gear oil to pool on the shed floor.
Rip old single spiner or locker diff out and smile as you wave good bye to it.
Grab the STI diff. Use a punch and punch mark the pinion nut and thread as to its position.
Get a good impact gun and remove the pinion nut. The flange maybe stuck fairly tight. Don't smack the sh*t out of it with a hammer as you will change the pinion depth and when you do up the nut again the crush tube will crush more which means pull diff to bits time. Use a harmonic balancer puller and your diff will last a long time.
Change the pinion seal. You can get this form the bearing shop as well.
Slide on the datsun flange
Do the pinion nut up to line up with your punch mark.
Chuck the diff in your Datto. Remember to put the spacers back in.
Install the Beta Motorsport adapters. ( you will need to re use the studs from the old 1600 output flanges)
Bolt up half shafts and tail shaft. (chnge the uni's out for new items. I like the Toyo uni's the best)
Fill the diff with correct oil. Needs to be a LSD type for clutch diffs Penrite make a good oil.
Drop the car back down.
Crack a JD (Job done) & coke.
Clean up the shed put your tools away and sell the old R180 to a 200B owner
If you have had the diff re set or the centre is new run it in for a few hundred k's change the oil and then enter a burn out comp.
