Has anyone installed power steering on their S13 with the engine still in the car? Specifically, I'm looking to install the SOHC p/s stuff (res, soft and hard lines) into an 89 with a DOHC. I would think because you don't need to cross the lines under the engine along the steering rack (since its SOHC->DOHC) that it wouldn't be too difficult... but I don't want to get in too deep.
