Turbo Keeps Boosting?

[chrissso]

Is that it? Is there anyway to put it back to stock? Is there no fix for this issue? Why is it doing this now and not wene it was at stock?

Don't be a pusseh. Get an ECU. If cost is a problem, sell skyline and get a barina.

ok i took her for a spin tonight, i took it easy in 1 and 2, 3 i floord it, it when normaly to .5kpa and paused there for a sec, then it started to creep slowley toward 1bar, now heres the thing, it got to 1bar and stopped, then came back to .9bar and sat then i backed off, when it got to 1bar i was doing about 130 so i backed off. so it wont go over 1bar and will come back to .9bar as soon as it gets to 1bar.

i wasnt really looking at the taco at the time but i never reached the rev limiter, so i think it got to 1bar at around 6k

See either two things are still happening here:

1. You have not plumbed it back to the actuator correctly and removed the controller

2. The actuator is bad and/or the wastegate flap

If you dropped back onto a working actuator correctly then you should now only be running 8psi. It shoulnd't be anywhere near 1bar. Remove the actuator and insure the wastegate flap can move freely all the way down and up again, re-install the actuator.

My suggestion would be to "Obtain" the service manual for it, and take a good look at the vac diagrams. I still don't think you have the lines right.

Edit: You said in a previous post that you replaced the actuator, where did you get the new actuator from? You are aware that different actuators can hold different levels of boost yes?

Chances are it's a 1bar actuator you have replaced it with.

with the hoses ive done exactly whatever they’ve said, I changed the actuator because I changed the turbo, the turbo I bought was a s2 and it came with the stock actuator, so when I mean I changed the actuator I realy changed the whole turbo with actuator.

as for the hoses, can anyone give me a pic of what they have? So I can refer to it and copy?

cbf reading the entire thread, I changed one of these back to a stock setup last week...

Looking at your pic the orange and green hoses are arse about.

I don’t think it matters mate, cos there both blocked

Ok..if you think it doesn't matter. That's fine.. or you could take 20 seconds and put the hoses on correctly.

Goodluck

check the intercooler for a boost leak
