You'll have to buy yourself a sensor and either drill and tap the downpipe from the turbo, it has the boss cast in place for the sensor but its not drilled. Or get an exhaust shop to weld a mounting bung a bit further down your exhaust.
Does that gauge work with a wide band or narrow band sensor?
I'd assume its meant to work with a narrow band sensor if its meant to work with the car's standard sensor.

i have no idea but if its going to be such a mission then ill just exchange the gauge for a diff type mayb volt mtr or oil pressure

The sensor will cost you anything from R700 - R2000 depending on what sensor it is.

Sorry poizen
Those Autoguage narrow band sensors are really an EPIC waste of time.
In all honesty I have not seen a wideband unit with sensor and all for less then R1600
Get a Nice Oil temp, Oil pressure or something like that because if that narrow band shows a lean or optimal mixture while on boost that damaging lean, All you should ever see is rich and then you don’t know by how much

Narrow band sensors are as common as muck nowadays, any car with a catalytic converter fitted as standard will have at least one. So thats most cars these days. They all pretty much work the same, and output between 0-1 volts, so almost any narrow band sensor will work, just go find the cheapest. (I have no idea what they cost).
As for the bung in the exhaust, you could get one welded in just after the flange where the downpipe connects to the exhaust. Will take an exhaust shop no more than 30 mins to do that.
Go speak to Darren at Powerflow in Prince Alfred Street (near ICC), tell him Guy from the ST club referred you.

yea i think im gonna exchange it coz it jus gonna cost far to much money mayb a fuel pressure gauge

I would have thought a new narrow band sensor would cost between R150-R300, but then I haven't actually priced one.

Brand new sensors are expensive, what is the good of having a narrowband sensor?? You need to have a wideband sensor.
