Turbo motor not creating vacuum or boost!

[RR-04-RR]

P/s this is for an SR20DET motor, if you want to add in your comments on how this isnt a honda motor.. then dont bother posting

Hey guys

I've having a couple of issues with my car and i need your help asap!!

If its not fixed.. then i'll just take it to the mechnics

Well pretty much.. need to jump start my car today to get it going... Didnt idle well at all in cold.. pretty much stalls if i dont rev it
So i went for a drive ASAP and once warmed.. i notice that my car did not creat any vacuum or boost.. guage and boost controller shows "0"
Once warmed.. the car idles like crap

NOTE - these may not be relavant but just incase
- My battery is pretty much dead if i dont start the car everyday.. if i drive to work and back daily then the next day will be fine
If i leave it for more than a day.. i'll need to jump start it
- I also had tape on one of my radiator hose from the thermostat to the block (i think it is connected to them) i changed around the tape today, perhaps i pulled off a hose accidently and this is what is causing my car to be in this position?

What could it be?
Fried ecu?
Perhaps a hose pulled out which is causing this?
Turbo?
Leaking?

how did it drive when warming it up? check vac lines would of been the first thing i did

The fact that your gauge says zero, you should look at the vacuum connection for the gauge. You may have a air leak from there or somewhere else. Change your battery as low voltage may affect the ecu, especially if the car isnt running properly to operate the alternator.

Now this wouldnt happen if it was a honda ....LOLZ! :wave:

the cars crap idle definately makes it sound like a vac hose has been pulled off or damaged. its odd that its not making any vac or boost though.

Do you only say it isn't because of the gauge, or can you actually not hear the turbo spooling??? If there wasn't any vaccum your engine wouldn't be running, if your engine is running (even if shit) there is vacuum. so sounds more like a gauge/vac leak problem

Well it ran ok.. i just made sure i didnt stop and let it idle :p, i will do that today.. thanks

I can definitely feel the car is not making any boost at all, thank you so much for your input.. will def look into this problem

+1 for a air leak.
probably coming from one of your piping or silcone bends that you might have.
mate had the same problem. hope in your case this is a simple fix.

check ur ic pipe clamps and tighten them. get a new battery while ur aat it and replace the coolant hose.

Thanks so much for the help!

PROBLEM FIXED!! and as you guys have advised me.. it was a vaccum hose that was pulled out of the intake manifold

vids of the car hitting boost would be nice =D

Kind of hard atm.. breaks traction at boost so difficult to steer to hold camera atm :P

But car will be runnign at WSID on wed so hopefully i can get the camera mount and show you guys a vid:D
