Hi 280zen As to your Question of using R230 in 83ZX the anwer is not in the way that 240-280Z guys are doing it because the diff in a ZX is an integral part of the rear suspension so you cant use the later shortnose diffs. I have had a 200-240SX multi link under my spare car and it would be a lot easier adaptation than what Maichor has done with an early body. The later S14-15- Skyline rear cage has different upper arms and more upright strut mounting which I think would be more adaptable into 280ZX. Someone will eventually be inspired enough to have a go. Neil.

Ok I'm Back Firstly for Don I researched the carrier (case) Part Nos for 280zx -Z31 and they use the same carriers for both pinion sizes so jmortensens theory of thicker crownwheels for the smaller pinion appears to be correct meaning the Z32-S13 carrier should be suitable with both pinion sizes. My carrier came out of 200SX-S13 48/11 4.363, US 240SX was 49/12 4.083, European 200SX was 47/12 3.916. Since Z32and S13 were produced 89-94 it is not suprising that Don has found them to be interchangeble. Doug why you carrier is 13mm crown bolts so far I have no explanation, mine were 12mm with 22mm reach. Neil

Hi John, Be aware that a 55 aspect tyre will probably give you an even harder ride than before, you should have gone up to 65 or 70 aspect ratio. Noting that in 70 series they probably would be H speed rating. Going to a 195/55/14 is the equivelant of fitting a 3.9 diff ratio in place of your 3.545 which will cause a large speedo error. The car will accelerate like a rocket but run at greater rpm for the same road speed which will give you poor fuel economy. Just some additional things to think about. Neil

Thanks Don, Still leaves me with the suspicion that this may not work with 10 tooth pinions of 3.7-3.9 ratios but I guess we wait till someone tries it to confirm or deny the possibility. By the way Nissan went back to Viscous centre for 350Z. Cheers Neil.

Hi Don a few questions. 1- What was the ratio of the long nose that you installed the Z32 carrier into? 2- What was the ratio that you installed on the Helical carrier? 3- Also Doug71ZT has posted that his Z32na was 13mm crown wheel bolts. There was considerable discussion last year on this issue with stony and brokebolt and we still dont have the definative answer. Neil

Hi Doug Put simply the total shaft length for the outer CV that came off my S13 200SX drive shafts is 110mm and the distance from inner flange to outer flange on the hub is 72mm. On a 280ZX the rear axle housing is 127mm wide so you would need a shaft of 184mm. So as you can see unless the rear axle housing was extensively modified it wont work. The question- is the 240-260-280 rear axle housing any narrower? If not then the above applies to them also. Neil. Edit -1 Not that it should stop some enterprising person from fabricating a new lower rear assy for 240Z-280Z that incorporates, mounting for rear disc brakes and the multi link rear hub, Thus solving the outer CV problem in R230V conversion and lengthening the driveshaft reducing driveshaft angularity. Cheers Neil.

Yes Richard. I,ve drawn it all up in cad, located some one in Melbourne to shorten and respline 200SX-240SX driveshafts and will machine the Outer CV housing as well as the adapter. Ive ordered the last of my diff parts from Nissan when they come in I'll do its final assy. I originally measued the shaft lengths with the diff spacer on the right only to realise it needs to be on the left which alters the shaft lengths slightly. Note I am working on 280ZX earlier Zs may need different shaft lengths. No I am not going to make a kit as such just provide the info. As to tripod strength the driveshaft company that I dealt with last year said that Ford Australia trialled them behind 4.6 litre Cobra Jet? motors and found that behind the 6 speed man they failed because they drove the needle rollers into the tripod. So they went the same way as Holden using plunging type CVs. But if anyone else on this site has broken them please start another thread to discuss it. Neil

Thanks Doug This was timely and connects with the current thread on nismo centres. FYI 4.083 is 49/12. If it uses 13mm crown bolts is it the same carrier as R230V? As to the outer stubs on the driveshafts, I know that the stubs aren't long enough for 280ZX-Z31 hubs is that the same for earlier Zs? As many questions as answers. Neil

Ok this is getting out of hand. 1-2126 asked whether he could use the nismo carrier in 280ZX, if the carrier is Part No specific to 280ZX or Z31 yes he can provided he can get Z31 viscous LSD driveshafts or makes custom driveshafts. 2- What I was trying to point out in my earlier post is that in 280ZX and Z31 the 8mm side bearing spacer is used on the right hand side for both pinion sizes whether there are different offsets in the carriers or as Jon has implied there are thicker and thinner crownwheels you would have to ask a diff expert that has pulled enough apart. 3- But in the later 200SX-240SX shortnose diffs they use one carrier offset for both pinions using the 8mm side bearing spacer on the right for the larger pinion and on the left for the smaller pinion. 4- So if you see one advertised on ebay or elsewhere privately and the seller isn,t positive of what it is for or says it fits all R200s dont buy it unless it is cheap enough to take a punt. 5- I revise what I said earlier in that the bolt spacers need to be interference fit, if they are a neat fit you can probably you can just use the same sealant locking compound used on the bolts to keep them in place. 6- I am just finalising custom tripod drive shafts using the 200SX-240SX inner CV and 280ZX-Z31 outer CV with an adapter to make the outer CV an end stop instead of spring loaded sliding. Stay posted. Neil

Hi Guys, My carrier holes were 12.10mm or .476inch but if anyone was having them made you would want to check your own carrier just in case. The bolts aren,t press fit because they clamp the ring gear down and dont move there after. Neil.

Ok guys heres some info, If the carrier flange is the same as my viscous carrier then you wouldn't wont the spacers to be any longer than 11mm or .425inch (.450in flange thickness)you would also want them to be an interference fit into the carrier or they would rattle. Also Nissan used an R200H or helical in its 200SX S15 6 speed Man. Check with supplier what it is designed to suit as later carriers the ring gear flange is offset to suit the pinion gears used and use the side bearing spacer to offset carrier. S13 11 and 12 toothed pinion suitable as I did for 39/11 3.545 S14 S15 12 and 13 toothed pinion which cant be used with early ratios. Skylines that I am still researching have a 37/9 4.111 which may be suitable for 39/10 3.9 and 37/10 3.7 although in R32 with the range of engines they have the following pinions 8,9,11,12,13. If its Helical it should have the same spline size and count as R200V Viscous. So check before you spend money. Neil

Hi Jeff got email away tonight takes about 90 seconds at 56K let us know if any problems, Neil

Jeff Ive got a chassis drawing in PDF format that I can email if you let me know email address. Neil

Hi Garry. This has been discussed many times, the last time was only 2 pages ago in this forum. The simple answer is the driveshafts usually break first. If you want more info and personal experiences then use the search function under "R200". Neil.

The following info is derived from Z31.com parts fiche. 2 Pinion Open 07/83-08/85 38100-P6400 37/10 3.7 10/83-09/86 T 38100-13S01 39/11 3.545 09/85-08/87 38100-14S00 37/10 3.7 Alt -14S01 08/87- 38100-15S01 39/10 3.9 4 Pinion Open 09/86-08/87 T 38100-14S10 37/10 3.7 Alt-14S60 Clutch LS 04/87- T GL+GLL 38100-14S10 Viscous LS 01/88- T SS Man F5 38100-14S10 Additional European Info from http://www.300zx.lv Note this listing shows the above with the following exceptions applications above using 38100-14S10 are shown as 38100-14S01 02/84-02/87 T 38100-12S01 37/11 3.364 02/87- T 38100-12S01 All should show up on Nissans Master Parts List. Thats all Neil.

Ok Working off the parts fiche at z31.com I can pass on the following. In the 2 pinion open Diff the Ring gear bolt part No changes from the 9 month 1985 to 38120-12S00. The 4 pinion 0pen,clutch lsd and Viscous lsd all use this part No. The s13 open and viscous lsd also lists the same bolt part No. My open diff which came out of an Aus turbo had ring gear markings 31/10/85 is 12MM bolts, whereas the first one was out of an 84 open diff the ring gear was marked 11/83 was 10mm. Thats all the light I can shed on it. Neil Edit All 280ZX inc turbo are 10mm P/No38102-n3100.

Hey Ozcheek dont know how useful it is for 240 but pretty useful for someone with early 280ZX wanting to upgrade to bigger Z31 brakes because rear calipers are similar to all late model Nissan rear calipers, ie mounting and piston size. Hopefully somone else out there is looking so you dont have to junk it. Neil

What can we say. Looking at the schematic on page 106 there is no FICD on turbo and the manual tells you what all the components are for, as to what can be removed probably not much. Probably better to ask how someone else fitted similar after market items that you have or have a professional fit them. Neil

In that case i would use the 3.8 GM, cheap and easy, popular swap in Aus for older pickups. As for Nissan VG30 or 33 I have one as standard in mine and it is pig to change oil filters and had to pull engine because of broken exhaust manifold studs( poor quality, undersized ). Neil

Chucky Why dont you just use Nissans own 3.0 Lt Turbo diesel thats been around for a few years now, available in their small and large pickups or should be able to obtain in front halfcut from Japan. Neil

Hi I would agree with Jon in that you could remove the shifter extension back to the universal joint with customised shifter mount. That said if you can make it fit, given its size, it sounds like a cheap tranny. Neil

Hi guys Lasting impressions would be V12 E Type Jag at 130 MPH, Local Ford 351 GTHO when the gear stick popped out of gearbox 3-4 shift 100 MPH. Most enjoyable, delivering single headlight 330 GT Ferrari back to owner from shop, brief howl of exhaust and roar of intake will live forever together with the smell of old leather. It was a lovely powder blue metallic colour with Borranis and quad pipes and that was nearly 25 years ago Sigh!!!!!! Sorry started to drift away to another time. Neil

Sorry to get your hopes up, there doesn,t appear to be any availability of the complete inner CV. Provided you dont destroy an outer housing, balls cages and races are available through driveline manufacturers like GKN Spicer. Including oversize balls and races for well worn CVs. In going back through my research notes, something else I looked into was GKNs VL plunging CV joints, specifically CV288 which is a 6 ball 113mm outer diam 32mm wide and takes 27 spline 1.16in shaft. Which is used in both our domestic Ford and GM independant rears which you can see in the new Pontiac GTO for eg. For those going budget then the use of S/H CVs is quite logical but I can see in future if everyone is using 2 sets of shafts supply could end up being a problem. Making adaptors, new shafts and using other OEM components for the plunging type joints could be a viable long term option. I wont pursue it any further because it doesn't suit my 280ZX application but most certainly could be a viable alternative which also has the advantage of less driveshaft weight. Edit 1 oops last night I said fixed joints when I meant plunging my apologies to anyone who read it and was mislead. Hope this is useful info. Neil

Hi Tim when I was investigating this last year in Aus I'm sure they were available ex Japan unless what I was quoted on was the smaller R200V as used in N/A. I will look into it again sometime in the next week. Neil

Hi John glad to hear you are once again at peace with your 280ZXT, sorry but Im not big on childrens programs so I cant answer your question regards Brum. As to loose crank bolt, it is probably just one of those things that happen and Newton/Metres is the metric equivelant of Torque measurement, US is probably more used to Foot/Pounds. Anyway cheers Neil
