Little update, I've been doing small bits and bobs over the last month or two, but recently purchased a Nismo 2 way diff from sx-si! It's always been my goal to get one as its the ultimate drift tool to finish the car off.
Heres the diff and shafts, it's a skyline diff centre built into an S15 casing with original planet gear and pinion, which for me was the clincher as it was an easy swap and correct drive ratio! with the skyline output shafts and drive shafts it's an uprated and (touch wood) stronger setup.
So i polished up the rear casing and painted the shafts and touched up the back plate bolts with yellow too!
I also topped up my smurf gearbox oil, to help the box as it was feeling abit notchy
So my verdict on the diff is that it is brilliant! I was really expecting it to be clunky and noisy, but it's really quiet and only on full lock turns does it slightly skip round. Once it's warmed up it's more aggressive, but I haven't had any rain yet to give it a good test on my local "driftabout".
Gotta love Nismo!
