Looks like lots of good fun ahead!

That does sound strange. I would expect that the tunnel should be the same position in all BAs, so the pinion should be in the same place on all BAs? Could the diff be from an FG? Not sure if the pinion would be in a different place on them? Not sure if 30mm movement would cause a problem, but I think you would want to figure out why it would be different to what you have. All I can think of with that is that universal joints have limits on the angles they move though. You might want to look into that. I have a BA wagon diff at home which I can measure if that helps at all.

Hey Puff, When I got the request for a couple of photos, I figured he might have been a bit rattled by the whole "Might have accidentally broken the gearbox and then had a bunch more work to check and get it right". Its been a bit of a trial and would have thrown me a bit too. After that I could well be thinking "What might go wrong now?!" and want a bit of confirmation that its all correct. He has been working hard and making helpful posts for the community here, so when he wanted some photos, I was happy to spend a few minutes to help out. I expect I will have to remove and reinstall the gearbox at some point so the info here will also be helpful to me as well. I am looking forward to hearing that that its all working well again soon!

I believe that the Territory rear brakes are the same as those which Ford used for cars which got the 4 piston Brembos on the front. The standard FG rears are 303mm*16mm solid discs where the Territory rears are 328mm*26mm ventilated (significantly larger and ventilated). The Territory rears are supposed to be a very good upgrade - they are much closer in size to the 330mm*28mm disc used with 4 piston rear Brembos.

My Nephew came over so I could give him a hand with changing brake pads on his Mazda. He bought Brembo branded pads which they list as fitting his car, but they were slightly different shape and did no fit. Also on the same Brembo site they list other pads which are 6mm less tall (which would be the right ones). Have had a quick look and do not see any options for different brakes for his car, so this is making no sense....

In the interests of helping out the Falcon community I have purchased a set of the 325mm*32mm FPV brake upgrade discs to try with the Territory Turbo calipers. I was hoping to be able to tell you all "Buy the Turbo Territory calipers and the 325mm*32mm discs and just bolt everything together for a nice cheap brake upgrade option", but it did not quite work out that way. I have bolted everything to a BA knuckle and the caliper _just_ touches the outside edge of the disc. I suspect that a small amount of clearancing of the caliper or disc would have everything working nicely together. I might look closer at doing some clearancing of the calipers or disc to fit the 325mm*32mm discs later on. Before I do anything else, I want to make adapters for the Territory Turbo calipers to go onto Falcons to use the 340mm*32mm Turbo Territory discs as well as adapters for the Territory Turbo calipers to go onto Falcons to use the 355mm*32mm Brembo discs. All of these are now fairly low down my list of priorities as I have 6 pot Brembos for my two cars (still to be painted and fitted on the second car), so if anyone is interested in any of this, let me know as it would provide some motivation.

Did that give you motivation to work on it some more?

Sorry that you have sold it. I wonder if the new owner will be posting here?

Lots of good information in this thread. Thanks all for the contributions. I suspect I will be making use of this at some time in the future as well.

I am very impressed with the way you are getting stuck into new, complex jobs and getting through them. Well done!

I have a BA front knuckle that you could borrow if that would help with putting things together, but I am near Bankstown/Liverpool.

That seems like something that very few people are likely to know. I think you might need to have the parts side by side to compare to have a good idea if they might fit. There might also be other dimensions that are different as well? Where are you located?

Is this something where new parts should be used, or they are reliable/dont wear out, so reusing second hand parts would be ok?

Sounds almost fair that a block might not be happy at 45psi /1500HP? With broken stuff, I like to try to figure out the sequence of events. If you can figure out exactly what went wrong, you have a chance of knowing what to try to upgrade. in this case I think it would be interesting to know the bore thickness at different points and how the points that have split compare to the rest? If the bores are thinner at those points, you have a "dont use any blocks with bores that thin" reference point. Would also be interesting to try to figure out where the split started from and if partial grout filling might have helped? Sounds like "Operated outside of acceptable parameters" contributed too..

Rough idle, but driving ok could be intake manifold gasket. Can test by squirting some butane at different points where the intake manifold is mounted to the head while the car is idling. If idle changes, its sucking in the gas instead of just air. Can also test disconnecting wiring to each coil while it is running to see which cylinder is not running right. If you disconnect a coil and it runs worse, that cylinder was working.
