Just had to do mine, hopefully this will satisfy the SEARCH button
For the S13
Fairly simple but due to it's amzingly wtf placement it is a bit of a pain.
1.unplug battery
2.unplug harness going to battery
3.undo to bolts on the starter/solenoid
4.Unbolt the 2 bolts on the back of the starter itself. (the diagram is very simplified.) feel around for the 2 bolts, they are parrallel to eachother. And yes these are a fucking pain in the ass to take out. you can reach them from the top or bottom.
5.Remove ,yell expletives *fuck you you piece of shit* was my choice.
6.insert in reverse order,make sure the 'blades' match up on the back of the starter, should just slip right in.
Feel free to add anything I forgot.
This may help too
