i have the s13 fsm and the r32 fsm, and i've been trying to figure out the heater hose arrangement. can some one direct me to the right fsm page, or tell me which is the outlet and inlet on the rb20? thanks in advance

it really doesnt matter. it can flow either way. i have the lower on the firewall hooked to the hose going under the intake mani and the upper one hooked to the one on the rear of the block
