R230 (z32 Tt) Diff In To R32

Hi ppls,

I'm looking in to diff ratio's and diff swaps for my R32 as the std VLSD open wheels and the ratio is too low (numberically high) for the RB30.

I've been looking at a 3.69:1 ratio as for the way I drive it appears the turbo will be spooling perfectly as I leave corners etc. + the added advantage of improved economy with PULP soon to hit $1.50 per litre. :D

I've spoken to a few diff rebuilders and to simply swap a pinion and ring gear they want around $300-$400 + the gears which I can pick one up for $150, then I need to drop a decent center in it, possibly a GTR mech center for $550. So its going to work out fairly expensive.. $1100 or there abouts for a decent center and ratio change.

I then came across one diff rebuilder that said why not look at dropping a early 90's Z32 TT R230 in to it. They run the ratio I am after and with a few little modifications they bolt up.

'Apparently' swap the input flange and solid mount the front rubber bushes, the early Z32 R230's run the 5bolt half shafts. It sounds too easy as I'm sure the R230 I had a quick look at looked wider than my R200.

Has any one had any experience with the R230's or has access to one that can check out the rear cover plate?

hey buddy, a friend of mine bought a z32 diif to put in his cefiro (same subframe as r32) apart from the half shafts being 6 bolt, and the input being different also, there is know way it will fit in your subframe, its just too wide, aand you cant swap backing plates with a r200 (comlpetely differnet).

The only option, which he is looking into, is getting a z32 subframe. looks like it may bolt up. As for early z32's haveing 5 bolt driveshafts, my g'f has a 1889 tt zed and its 6 bolt.

Possibly the early model non turbo diff has 5 bolt.

hope that helps

What would be the best bet for a mate of mine with an R33 and the similiar problem to you Cubes... Except his RB30det is worse as he's putting an auto into it aswell.

Whats the best bet for higher ratio R33 diffs.. Would Z32, 3.69 ratios bolt to the standard R33 VLSD centre?

r33/32 all use an r200 diff (meaning 200mm crownwheel)

As long as as the crownwheel and pinion are from a r200 diff then all ratios are interchangeable.

There are heaps of r200 ratios available 3.69, 3.9, 4.11, 4.3 and more...

AS for the 3.69, u need the cw&p from s13's as they run r200's (3.69 auto 3.9 manual)

There are long nose (up to r31, z31 &s12) & short nose (from r32, z32 & s13) R200's & you can only interchange between the right length.

      Rb25 trigger kit and timing misalignment

      By drifter17a · Posted

      Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Hi...a little refresh. Is Nistune gonna be enough to run BoV? Or do i need some proper ECU?

      Yep that's pretty much what I want to see. Racecars that look and sound like the Group A but with newer tech underneath to make them faster and safer. I'm sure there's enough VK-to-VN commodore, E30 BMWs and Foxbody mustangs shells around to make up a decent number of cars with hopefully a couple of sierras, rx7 and R31s in there too.

      Contact Jessestreeter.com/Skevas Racing/JustJap for a new r34 rb gearbox or go a cd00# conversion. No point playing with unknown condition gearboxes.

      Such a shame places like Amaroo Park have been redeveloped, smaller tracks always make for good racing. Cheers for sharing @PranK there's some good Lakeside video's too. Its so hard with older the cars as parts are so rare and everything was made for a particular chassis at that point in time. Even the V8 Supercar Blueprint era cars are all different between each chassis within a team as they learnt things and made improvements. The COTF cars between each Chassis builder is different too especially motor/oil systems/intakes. The Group A stuff is worth so much too especially chassis with good history. The only way to do it would be composite panels and similar engine drivelines to the original cars. Ford sierra running Focus RS driveline, Commodore running a short stroke LS/LT or a Falcon with coyote and a H Pattern dog box. Could use a standard ecu across all models with a Torque Map and DBW for parity which is not even used in Supercars currently. Hell a TCM is almost a full chassis car these days and the suspension is not even close to standard style in the front running cars.
