I just purchased a s14 with a sr20det and i'm in the middle of fixing some of the problems that came with the car along with a tune up. The one problem i seem to be having is that i THINK i have a boost leak. My reasoning is that i'm only getting 16-18 in.hg vaccum at idle and i'm only reaching 5 lbs of boost. I've read that your vacuum at idle should be 20 and stock boost is 7 lbs. Also, whenever i boost and hit 5 lbs, it starts to slowly drop again. Now i could understand if i was boosting 18lbs and out of the efficieny range of the turbo, , but i dont expect the boost to drop off at 5 lbs.
Anyways, if this does sound like a boost leak, where are the most likely spots? I checked the car earlier today and couldnt find any leaks but i guess i didnt look hard enough. Is there any easy way to check for leaks? If this doesnt sound like a boost leak, what else do you think could cause this problem. Thanks!
