rear end gearing
« on: 11:41:33 PM / 22-Jul-11 »
I have two s12's
one is an 85 with the ca20 rear end gearing
the other is an 87 with ca18et rear end gearing
i bought the 87 because it had a sr20 already in it and turbo goodies and was a good price.
but the chassis is not great
i plan on swaping the sr20det into my 85 with the ca20e rear ended car
both are irs open diff
what i want to know is does anyone have this motor with either rear end and how is the top speed
my speedo has never worked in either car so i dont know what to expect
