Don't just boost it cause u won't recieve max gains and only strain other components.

U need a cooler and turbo back exhaust at least and probably some sort of induction kit

Do a full exhaust first. The car will make more boost pressure by itself as it is taking away a restriction.

Upping the boost on a standard car won't give many gains as there are still large restrictions.

The vac line that doesn't connect to anything, Is that the line that the other end connects to the boost controller? Because if the controller has no idea what boost the car is running it wont be able to regulate it.

That hose needs to go back into intercooler piping. As stated it controls boost.

you can get an air nipple welded or a screw in type from like repco of sorts.

Im sure this has been discussed many types, search intercooler, nipple.

jacked thread here... soz :P

But there is already 1 vac line going to the plenum that should be all the controller needs to tell what boost pressure the car is running. Why would you need 2?

just rip all that crap out and connect one side of the boost controller to the wastegate on the turbo and go to autobahn or repco and grab a little brass bard fitting and screw it in the cross over pipe( will have to drill and tap it first) then plug the other sside of the boost controller onto your bard fitting and hey presto your done. go for a drive and set it at around 10- 11 psi on a stock setup. anymore and well we all know what happens. lol

      Hello Everyone

      Welcome.  Glad to hear that you have gained some knowledge that has helped you. I believe the only fix for the power steer belt is an electric conversion with a Holden astra pump. If you get a chance, post pics of your car, please. 🙂

      to have this type of adjustment possible with a curve as I wish, what budget (engine) should be planned?

      Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
