Quick can someone tell me how their stock sr20det boost lines are hooked up?
Where should the BOV be ran from?
Where should the Wastegate be ran from?
I have been searching everywhere and I cant quite find this info.
My BOV is hooked directly into my wastegate and I do not believe thats right at all.

Re: Boost lines (S14Jer)
piece of cake... after dozens of failed tries.
BOV: first look at your intake manifold. your throttle body is the thing that the throttle cable connects to; you should see THREE little nipples (just like my cousin, frank. ..jk), asuming there's no hoses hooked up. the nipples are maybe a quarter inch big, a few different sizes. the top right nipple (looking AT the engine from the front of the car) will go to your blow off valve. it doesn't have to be pretty, but make sure that your little hose is good and you use good clamps!
Wastegate: on my SR before i put on new piping and other b.s., the source came off from one of the black plastic pipes. i think normally it's on the hotpipe, the pipe going from the turbo to the intercooler. sometimes with new pipe setups, you'll have to find another source.. like me. this is where my frustrations, resulting in broken things, started from. then it hit me, like, "DURRRR." which brings us to your concern...
i'd have to go outside to look, but i'm almost positive that my w/g is also hooked up to my bov. the bov and the w/g run off of boost, or pressure, so it makes sense that they can both be ran off of the same source.some guys might say NO NO NO N ON ON ONINOe, and they're not wrong for screaming it.. but i don't have the ability to weld aluminum, so i'm pretty much SOL. i think the big thing to worry about when running the w/g off of the bov is to make sure the w/g line is as SHORT as possible. more hose means more air, and i'm to understand shorter means quicker response.
oh, and the top left nipple on the throttle body goes to your fuel pressure regulator, the weird top-hat-looking thing at the end of your fuel rail, and you can run a boost gauge off of this one as well. keep the line to the fpr as straight as you can, if t-ing off of it. the bottom nipple can be molested. it goes to the charcoal canister on the left-hand side of the car (driver side, in the states) which looks like a black piece of garbage.. but actually serves a purpose. you can completely cap this off at the throttle body and the canister, because you really don't need it. it's for emissions or some crap.
its a good idea to invest in some good clamps too; those POS ones nissan puts on the car aren't always the best choice.
