4am and I am thinking about the S13 again. Hopefully with some temps above 40F, I will have a chance to play with it for a while.
Eitherway, the plan is to do two things to the power steering system.
One - to relocate the reservoir closer to the clutch master cylinder
Two - replace the weak ass excuse of a cooler with something better, right along the oil cooler and route the new hoses (1/2) as needed. See it here
