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.......

      R32 GTR Bonnet Hinge Bolts

      By SteveL · Posted

      From my bolts, standard M8 with 1.25mm thread pitch (M8x1.25mm).    Length is 19mm under the head and has a captive 18mm OD flat washer.   20mm length from a bolt shop is what you'll be able to get.   Make sure they're zinc plated.    If you're concerned about strength, grade 8.8 will be more than enough. Original PN is 01121-04971.  Now discontinued according to Amayama but that's because it's one of the parts that's been captured by the Heritage program, which explains the ridiculous price.   New PN is 01121-RHR20: https://nismodirect.com/nismo-heritage-bolt-pin-hinge-hood-bnr32-nissan-skyline-gt-r-01121-rhr20-01121-04971/ About AUD33 converted from Yen in the above link but that's just one example. Interesting that the hinge-to-body bolts are still available non-heritage.....PN 08116-8161G around $2 each (amayama).    Same thread but 16mm long.

      Well, if that filter was impeding fluid flow, then it could have similar effects to faulty solenoids. The TCU will register a fault when it does something (ie, changes the state of a solenoid) and does not detect the required result. If there are other causes that can make the same lack of result, then they will be indistinguishable to the expected cause for which the TCU has a code.

      R34 RB20DE NEO coilpack?

      By GTSBoy · Posted

      Yellowjackets, red ones, blue ones (other than Splitfire) have all been demonstrated to be unreliable on turbo engines. That unreliability can be anything from outright failure (ie, 4 out of a set of 6 working out of the box) to just not being strong enough for the task, on a boosted engine. Not enough of us care about NA engines to know whether that unreliability is an issue for the undemanding needs of an NA RB20. I should think though that the DIS-008 should fit the 20. There's not really any reason for the head/coil mounting area to be any different on those 2 Neos. I wouldn't be buying Splitfires, or any other old tech coilpack, for a car in this day and age though. I would buy modern pencil coils and do what needs to be done to adapt them to the loom. That's relatively trivial these days, with numerous kits for fitting R35, or Audi, or Yaris/Corolla coils.

      Keen to see how much work is needed to get an abandoned Skyline going. My R32 has been sitting idle for three years or so but finally got some time to get it going again. (Also lurking SAU and trying to hit 10 posts so I can start my own intro thread with pics)
