Hi all,
Before you say it, I've read almost every diff related post I could find but I'm still scratching my head.
I have a 240z with an RB20DET (basically stock, 150kw atw) and RB gearbox and I'm not sure what diff ratio I currently have but 2nd gear just keeps going, and going. No joke I can pull away from a standing start in 2nd and get to about 110km/h. Great party trick but not overly practical.
So I want to change my diff so I'll have more acceleration and a LSD. The car is mainly street driven but I would like to do a few track days and 1/4 mile passes in the future. I've budgeted around $1500-2000 and was thinking the "easiest" option would be the 4.44 ratio (I believe the R32 came with a 4.363 ratio) LSD R180 from the GC8 Subaru STi with side axles from Wolf Creek Racing.
So.....have I budgeted enough? Should I stick with R180's or go R200 diffs? is 4.44 the right ratio for me? Does it matter what sort of LSD it is as its a street car? why do some people say the R180 Subaru swap isn't so easy?
Thanks
