I dunno, allwell updates are as follows, pulled everything off today left and right side of motor. Injectors, rail manifold turbo, lines front/dump pipe, replaced the manifold studs awaiting the gasket from 3lit3_32 (aka Dan) tommorow and should have everything bolted back together by tommorow evening, I have to admit its an experience of a life time when ya first do a job like this, especially thos broken manifold studs and removing the fuel rail for the injectors.

Will take some pics when the job is done, HOPEFULLY with no bolts missing or left over cough cough i hate when that happens. But so far so good.

For those noting on broken manifold studs, Im too lazy to do this part myself also noted do not have the tools to do it mind you.

But if you are in the brisbane QLD region Thread Tek are the way to go (1300 THREAD) they may take all afternoon to get there, but 15 minutes for them to remove 3 manifold studs well worth it. Only problem $99.00 to remove those 3 studs, awell had to be done thanks guys.

Also Lees exhaust on moss street, $1.00 per manifold stud being the M10 x 1.25 pitch 50mm and 50c per nut, well worth it beats repco anyday for those parts. :)

Also must thank Dan (3lit3_32) for his assistance so far and being able to get parts at a hard to beat price :) hope i can add that.

Anyway that is all and will keep you guys posted

Cheers and out

Ok so my compression values are in and leak down values what do you guys think:

Cyl1: 155 8%

Cyl2: 155 9%

Cyl3: 150 10%

Cyl4: 155 12%

Cyl5: 150 12%

Cyl6: 155 9%

Since last dyno made 178.9 rwkws before front pipe install so still running standard front pipe and dump

Also did power run whilst doing comp values to see if still in tune, seems that it is and with the new front pipe being the 3" complete front and dump comes to a new value of 197.3 rwkws.

The difference in IT's was 39 before and new of 41 with this one

So i think it would be safe to say that my project should be done mid november now :) woohoo

Cheers

no offence man, but those leakdown figures are bad.

Mine was no more than 3% after 100,000km, and 10,000km of that was with a GT30 at 18psi, and 40,000km was with the standard turbo making 210rwkw with toluene at 13psi. All cylinders were above 160psi - but your compression is ok...Jus the leakdown...its not good...Well thats just me.

You might want to get a rebuild before you start moving to cams etc.

You'll get HEAPS more power by putting in forgies, rods, and lowering the compression a tiny bit to run more boost.

Cams won't do that much difference at this stage, but make your motor wear a little quicker.

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
