Hi guys can anyone tell me if the R33 diff will fit in a BA falcon?? both being IRS diffs if not will the diff gears fit??

Do you not see the absurdity of your thread?

Just because two cars have IRS it doesn't mean the diffs are designed exactly the same. It's very likely that falcon diffs and r33 diffs are internally and externally different in many ways.

Guys, be fair

The R33 diff is a common conversion into BA falcons in drag racing and speedway circles. The trick is, that you need to use a front diff out of the GTS4 (NA). This will bolt straight in but you'll then have to convert the Falcon to 4 stud at the back. You'll also need to fit the Skyline steering rack and lock it out, but this has the benefit of giving you adjustable toe on the back of the Falcon. If you're half smart you can put a tee line into your power steering return lines, install a couple of electric solenoid actuated pilot valves and connect this to the unused terminals in the Falcon ECU to give you HICAS (you;ll need to call your local Pirtek dude to make up the hyd lines for you, as the Skyline and Falcon hydraulic fittings are different - Skylines use 1/4" BSPP and Falcon uses 3/8" NPT). Again, a little known fact that Ford played around with HICAS style rear steering, but gave it away as too costly on their budget spec taxis.

yep, hotrodders and modifiers do it all the time, but they generally pick on ford 9", chevy 10 bolts, or jaguar diffs etc etc

I even had landcruiser diffs front and back on my Hilux [supercharged 3.8 v6 holden conversion], so it can be done.......

      Mistakes were made, my R34 Story

      A Pillar forward?   The part above I was just looking at was the reo bar, I'd replace it, UNLESS the panel beater is GOOD. From your early photos, it did look like the chassis might be tweaked, or at the very least there was tweaks in radiator support. I'd personally do a new / second hand unmolested reo bar, and drill it, only so I know underneath the pretty painted front bar, there's not a mess of other metal that's been hit and smacked.

      Yes no yes. Pineapple rings do do a certain amount of subframe "locking up", in that they do add some resistance to lateral movements. But the primary reason they exist is to alter the driveline angle. Depending on how you install them you can either increase or decrease rear traction __ a little bit __ by changing the angle of the lower control arms relative to the car/pinion angle. The thing is, given what they are, how and where they are installed, their lack of engagement with anything in particular, there's a limit to how much benefit they can offer. The GKTech collars put metal into the space in the stock format bushes, thereby limiting how much give they have. The rubber is still there to take up some force, albeit perhaps preloaded a little by having some extra metal jammed up into it, but the increase in stiffness comes from making it so that the stock format bush can't deflect that large bit of rubber over into the space adjacent to it, in any direction. Top AND bottom. Which the pineapples certainly do not do. As I said in my other thread - I'm convinced.
