Hoping for some help. Basically my AE86 is running about 4500RPM when in 5th gear around 60mph obviously not great when using as a road car on the odd weekend and a bit of fun. Therefore to get more top speed will I need to change the CPW and if so what ration? And change the LSD and is 1.5 best as I'm not a pro drifter and only use my car for shows or meets and occasional drift? Thank you in advance
That sounds like maybe a 4.7 in yours. Potentially look at around 4.3? I would probably go for a 2 way if you still want to use it for drifts etc. Look into a solid pinion spacer too if you'll be swapping out the FD and diff anyway.
