Is it the same as the S13's? right behind the clutch master on the firewall? the big black thing? im assuming its the clamped hose on the side closer to the fender that I have to pour seafoam into correct?

Um the brake booster wouldn't be behind the clutch master cylinder, but it would be behind the brake master cylinder

there should only 1 hose that connects to the brake booster. its about 1/2 inch black hose. pull it out and u should feel the vacuum from the engine. use the seafoam in a cup or something and stick the hose into the cup. suck up a lil at a time or else engine will stall out. i've done this on my s13 and it was smokey as hell haha.
good luck with urs
