  1. my 180 idles for 30seconds to a minute and then smoke starts coming from under the turbo where my wastegate sits..

    Things that i suspect that it could be is that i sanded off the flange smooth that connects to the wastegate carefully ofc to not get metal shavings down inside my manifold

     

    Could this be metal burning off inside the dump tube that runs under my car?? and could i just idle the car to where it will all burn off eventually?

    The smell is not coolant or oil but much more like a metal burning smell


  2. Most manifolds I see situate the wastegate 0-20cms away from the manifold, and that seems to perform fine. The further away it is, the worse the control and spool will be, as you're routing a good amount of gas away from the turbine housing in order to fill up a capped tube.

    Yea mine is positioned right around and under the turbo 1 foot away from the exhaust manifold..

    I get a hell slow spool which i though it was the distance of the EWG, Could that distance cause exhaust gas build up and overheat issues?


  3. Car is a 1994 180sx black top sr20det with garret 2860rs turbo running external wastegate

     

    So i just changed my manifold gasket, turbo/manifold gasket and dump pipe gasket and now i have smoke coming from the turbo manifold area?

    One thing i forgot to put back on the car is the external wastegate boost pressure hose on the pressure side of the intercooler pipe but now when it idles for 20/30 seconds it starts smoking a little around the manifold area? the car hasn't been driven but only idled.

     

    the smoke smell is only coming from the external wastegate pipe itself, i smell inside the exhaust manifold and dump pipe and nothing smells like it's burning, one thing i did which was probably the cause of it is i used copper high temp sealant around where the wastegate bolts too as i didn't have a metal gasket on me and also where the dump pipe connects to the front pipe. the sealant is rated to 60 - 370c

     

    I have ordered new metal gaskets for my wastegate and dump but before i bolt that bitch back on Any info will be much appreciated!


  4. So basically my problem is my fuel pump keeps cutting in and out randomly, iv checked my fuse which is all good and iv also swapped my relays so i know the relay isn't the problem either

    i can get the car running by bypassing relay number 2 and 5 and my fuel pump stays on but not 2 and 3 which everybody on google says to do and works for them

     

    on my relay number 3 and 5 have a break indicated on the relay which Leeds me to the question of does number 3 need a constant power to transfer power to number 5 when the relay connects that circuit?

     

    Iv checked voltage from the pin sockets on my relay socket

    1 - constant 12v with ignition on (ecu power?)

    2 - constant 12v with ignition on

    3 - nothing with/without ignition on

    4 - nothing with/without ignition on (power wire to fuel pump)

     

    all sockets have an earth apart from 3
