Having owned an AE86 and an S12...
S12 handled much better, but it was the IRS + LSD + 4 wheel disc version. Power was shite because the CA20E engine belongs on the bottom of the ocean as a boat anchor...
Steering is a bit heavier in the S12 and due to the longer bonnet (and much longer engine bay) you get the illusion that all of the weight is infront of you.
I miss my S12, I don't miss my AE86
I would own an SR20DET IRS model S12 any day of the week...
All nissan engines starting with CA** belong in the ocean, holding your boat in place
