R33 Diff In A Ba Falcon?

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

u wouldn't happen to know what the difference is between the front and rear diffs out of the skylines.???

The front diff is in the front and the rear diff is in the back

the front diff is open but you can convert it to LSD with a Phantom Grip assembly. To increase the locking, you use coarse lapping paste between the faces. Note you'll need to build up and machine the faces every 5000km because they'll wear out so quickly.

Why do yo9u want to? Why not just put in a falcodore clutch type LSD and be done with it. The viscous LSD isn't all that great and any entry/mid level aftermarket centre you will get for the 33 diff will be clutch type anyhow. Grab a rebuilt Falcon LSD, chuck it in and bobs your uncle.

      Looking for a part number for this part here

      By Duncan · Posted

      So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

      Duncan's V37.......race car?

      Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
