i thought it was easier to use the whole s14 motor and all the accesiores and just make it work. thats what i did, you just need to change the speed sensor on the tranny, and change the coolant sensor back to the s13 so your gauges will work right. and have taylor make you a harness so you can use the s14 internal coil. i have lots of ka parts for sale so pm me with what you need.
