[Charlie4401]

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??

[zebra]

I'm just going to say yes for teh lulz

[babyskyline]

ahahahaha bloody falcon owners

[turboedsloth]

Yep bolts straight in. With some modification to the subframe, half shafts, mounting points of course

Op, do try it and let us know how it turns out.

[Mohsen]

Yeah it fits

[Sunkist]

it fits, if skyline wheels will fit the skyline diffs will fit because they are connected.

Given I've seen a few xr6 turbos with R34 GTR wheels on them... You'll be right for sure.

You'll just need to make sure you swap out the shafts as well, not just the diff assembly.

[R31Nismoid]

Well it's your thread, you tell us?

[Charlie4401]

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.

[Charlie4401]

yeah i do know they might not fit thats Y i'm asking... thought some one might know. I'm just trying to find out if the whole IRS will fit or if the centers will swap over???

[zebra]

have you ever looked under either of the cars???

they are not even close to being similar.

You might as well ask "will a 9" diff bolt straight up to my Daewoo Lanos"

[tridentt150v]

I have to ask..........why????

There are spare skyline and falcon diffs aplenty, so why?

[The Bogan]

I saw a mini with a blown 8 years ago at summer nats, it had a 9 inch, so with enough money and time anything is possible.

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.

True

[tridentt150v]

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.......

Welding a couple of brackets to a live axle is a little different to cutting out the whole back end of a Skyline to fit the Ford IRS though.

Jag Rear ends are easy due to them just being trailing arm
