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.

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.......

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

      R33 GTST S1.5 Fuel Gauge Issues

      By tsirtsa · Posted

      Hey guys, have searched the internet all over and no one else has posted about this issue I'm having so here it goes. My fuel gauge was reading quarter full when it was actually empty, had a few other issues too and decided to swap to the proper ecu (had a nistune z32 ecu which came in the car) and now not only has the issue remained but it's actually gotten worse now reading half full when the gauge is 0. Anyone got any clue how to fix this?

      God damn. In 2 or 3 years I might not need 4 doors anymore! What a concept!

      There's a lot of high mileage 335's out there with minor mods who cope with a few track days a month and then behave nicely as a daily. I don't want to keep throwing money at this car, I'm not in it for much yet  and once I get the LSD there's really nothing else I need to do besides keep up to date with maintenance. Everything that breaks easily has been handled (minus HP Fuel Pump) which should give me a lot of trouble free motoring in future. It's definitely inside BMWs' "horror period" I get that, but I do think you're being a little overly harsh. I'd like to hold on to this for only another few years at least and then consider a step up into an F80/1 M3/4 when I can afford a good'n. I also like B58's and would move into a M235i or similar when they're a bit cheaper.

      I mean nah, lets be honest it's significantly worse. BMW's are absolutely not the same age, replacements are not the same level of robustness. Most would say an E36 is more solid than an E90X and I would still say an E36 is a little more rickety than your equivalent R chassis over time. BMW pretty much have a huge void between E36 and anything with a B58/ZF onward. I kinda get the appeal if they work, but they just don't. I get that the vibe is "do a track day in executive comfort" but in all seriousness, a VE Commodore is as comfortable and certainly more solid* around a track, and they are hardly up there in the high list of "Excellent track cars". See also: Barra Turbo with coilovers or _something_. I mean a great deal of these cars/choices are always irrational, but I at least try to stay rational, or at least have some rational argument why I did X and not Y :D. My pet peeve is irrational badge snobbery. There is no reason to buy a Luxury SUV when anything from Kia will do the job better, and cheaper. I know someone who has a twin turbo diesel X5 making 400kw or whatever and as soon as he opens his mouth I say nothing but "You are an idiot who has wasted your money" and tell him to buy a Tesla Model X/Y as it is superior to anything he will do with that car. (he does not like this, but he deserves it, just trust me..) But Prank seems like a nice guy. I want him to sell this 335i before sadness kicks in more and buy something far happier at the track, like an 86, or a Megane RS, or an Evo, or even save the money on mods and buy a 440i/240i/etc and bypass the painful years between 1997 and 2015 for BMW.
