R33 Diff?

[ryanVTV6]

Hi guys just wondering if anyone can tell me if my diff is LSD or not, it's standard as far as I'm aware. Car is r33 series one rb25det. Haven't driven it yet, any markings I can look at on the diff to give it away?

Cheers Ryan

if it's a gts-t, then most likely yes. there is a simple way to test it though. jack the car up so both back wheels are off the ground. have the car in neutral with the handbrake off (so wedge something on both sides of the front wheels to stop the car moving). then spin one of the wheels. the direction that the other wheel turns will tell you if it's a LSD or not (this doesn't apply to all diff types though).

if the opposite wheel spins the same way as you are spinning the wheel then it's a LSD.

if the opposite wheel spins the opposite direction to the way you are spinning the wheel then it's an open diff
