hey there

thanks for popping inmy weakest skill is mechanics, im trying thouI'm trying to figure out where these hoses go, and if where i placed em are correct.i tagged all of em so you could refer to em easy as 1,2,3, n 4.

your help will be mostly appreciated and i'm very generous so i might be able to help back sometime^^

ok I dont have the whole answer but I can get you started.

essentially with vacuum hoses everything goes into the throttle body they track the amount of air pressure going into the cylinders.

your BOV, wastegate and the plug on your intercooler piping, and intake manifold vaccum ports - are all that really matter.

you can bypass the point where 3 and 4 meet. delete that little device i dont know what that is.

here is a diagram of the vacuum hoses

it has all the answers, bypass any components you dont have and go unto the next thing.



also you can get a FSM for the sr20det.

hey ...sorry I don't understand anything.I'm a newbie. I look at the pictures and the real thing and they are pretty different.I was able to figure out a couple of things, but its still donst make it clear enough to make me the courage to start the car

ok dont worry

I felt the same way when I saw this. but its all there. just look carefully.

you'll have to read more. to get a feel for the whole thing and what is what.

focus on these first.

- the turbo waste gate plug- the IC piping hole plug - the BOV plug - and the 3 plugs at the throttle body.

can you post a pic of your WHOLE engine bay.

I think you can drive it, its just that the Idle and boost pressure wont function perfectly. I might be wrong tho

that diagram has the answers for you, you may not be able to get it in 30mins time but after a good gander it will come together.

Alright, to me it looks like #3 goes into a solenoid (piece by the P/S canister), then turns into #4, which goes to your wastegate actuator. #3 should be hooked up too the cold pipe (which it is), #4 after leaving the solenoid by the P/S canister, should be connected to the nipple on the wastegate actuator (silver/goldish thing connected to the front of your turbo). If you want, you can completely bypass your boost controller and run the #3 vac line from the cold side, down to the wastegate actuator, where #4 is connected. This will allow your engine to run on factory boost settings, which is 7psi. #2 needs to run to a vac source from either the intake manifold or the T/B, preferably the intake manifold. Same goes with the BOV, it needs to see a vac source, so either by the T/B or the intake manifold. Hope this helps, good luck getting it running.

cant figure it out ><heeeeeeeeeeeelpi think im missing a couple of t's and hoses.I might be able to just hook it up stock psi but i cant figure that one either. i know the cold pipe to the wastegate, but after that i dont know what to do with the rest.number 3 has 3 nipples, so i dont knowwhat to do..is like..overwhelming for some reason. :P

Hook #3 to the wastegate actuator, it the goldish thing I told you... You are probably going to have to T or Y into some of the other lines by the intake manifold. One step at a time, remember the 2 I told you must see boost/vac source.

yeah I got to that part. after that I don't know.I took a bunch of pics imma show in a few after i load em.

the intake manifold side is done though I believe.its the exhaust side that I'm having trouble with.Ive been dealing with this problem for almost a week already ><I dont know if the cars gonna explote or something if i put the wrong hose in.

also theres on electronic aparatus which i believe belongs to the upgrade boost part, that has 3 nipples, 2 on top n 1 in the bottom.its next to the brake fluid canister.I dont know what to do with that either.also i think imma run down advanced auto parts now and get a bunch of t's or y's...are they the same?and hoses to plug everything togather.

HERE are some of the pics that i hope would help finish this problem.a engine bay pic as requested. sorry it took so long.

thats how i have the car right now. I'm not sure if i can prepare it to work with recirculation so i guess i could set it to factory psi so it just works, and i can figure how to up the boost later.













mmmm by this last pic imageshack woulnt want to let me do it anymore. srvr woulnt load n stuff..i wonder...WTF?oh well.hope its useful.:D wanna turn on the car
