  1. You would be mistaken saying DR30's have 4 bolt half shafts.

     

    All of the factory DR's I have and have seen have the conventional 3 x 2 (6) bolt outer flanged half shafts.

     

    I didn't ask the question to be told what we already knew from Japan, what they came out of doesn't increase the availability out of Japan. I have seen 3 pairs of them on yahoo in recent times and have purchased 2 of them, the other was by far, more than I was prepared to pay as with freight the item was over AU$1200.00 for the pair and I could make them in Oz for that.

     

    Regards,

    Cool if all DR30 come with 6 bolts I am only going by the Nissan FAST catalogues and the partnumbers that match the 4 bolt units found on other Nissans ie Z31.

     

    FYI going by the FAST the DR30's with the FJ20 (ie pre 83 and non turbo) had the 6 bolt type and the later FJ20T powered cars have the 4 bolt type.

     

    See attached screen shots for reference - again I am only going by the info I have at hand and trying to give you more cars to look at that might have the same axles you are looking for - again from info in the FAST (assuming you have those models in Oz :( )

  2. NissanParts.cc still prices up the part so that usually means it is still available from Nissan - usually.

     

    I was the one who found the 38335-N3220 partnumber after spending a few hours looking over the Nissan parts catalogues I have. That partnumber is used on the YS31 Nissan Cedric/Gloria from Aug-92 up to Aug-99. I am surprised all the stock has been used up already - given the old S30 partnumber was available for almost 30 years I would have thought the SY31 partnumber should have some stock left after just 10 years.

  3. Are you sure the shafts are the same? I had HR31 turbo shafts in my car and they mounted to the companion flanges with 3 sets of 2 bolts and from memory have 3 ball bearings in the CVs? The Z31 turbo shafts I'm using now are the same as your pictures with 4 individual bolts and 5 bearing CVs.
    it depends on the model of R31 but yes there are some R31's with the 4 bolt CV shafts as shown above :) I know that the DR30 has the same shafts as the Z31

     

    FYI the same Z31 shafts are also on some JDM models of the following cars

    Y31 = Nissan Cedric (VG20DT, VG30D)

    F31 = Nissan Leopard (VG30D-ULTIMA)

     

    Now I did find another cross reference partnumber and it is used in the following models (again the 4 bolt version) on the RH side

    C32 = Nissan Laurel (RB20DET with R200 4.11 fitted)

    R31 = Nissan Skyline (RB20DT)

    F31 = Nissan Leopard (VG20T.XS)

    S12 = Nissan Silvia (CA18DET)

    Z31 = Nissan 300ZX/Fairlady ZR1, ZR2, 300ZR

    and the same partnumber used on a LH side of these models

    Y31 = Nissan Cedric (VG30E.Y, VG30E.MT, S.VG30T, VG30T.BROV)

     

    I am sure with more time alternative part numbers could be found with some research etc.

  4. I have pair from the first batch a year or so back. I am happy with the product (purchased mine from ebay back then and shipped to me here in NZ in no time at all)

     

    Pleased to see others can now get these again. Well done to grndfx for getting these back into production.

     

    Now only if the same could be said about other parts for our cars (thinking mainly so of the harder to get rubber parts ie rear hatch hinge boots etc)

  5. If your going to the trouble of doing this - why not make it 3 VFR800 engine = 2.4l V12 :) now that would be something different in a zed :) as most install a V12 that is somewhat larger than that and from another car - 3 x VFR800's engines would still be small and light weight too. However I have not idea if this is even possible. But as I have owned 2 x VFR800 and 3 x VFR400 I know why you would want to use two of these engines I just love those honda V4's.

  6. Ok here are some pics of mine. The fronts are 225/50/16 on a RS Watanabes 16x8.5 -6 and the rears are 245/45/16 on 16x9.5 -19

     

    First some pics of the rubber fitted - Toyo RA1 (click on images to see larger pics)

    Now some pics of the rim fitted to Dad's old S31 Fairlady Z with stock suspension and body work - showing the stretch on the fronts

    thumbs_testfitwheels7.jpg thumbs_testfitwheels4.jpg

     

    And now the test fit on my zed with the custom steel flares - no spring just blocks of wood to check what a fully compressed height would be like to ensure inner guards were made with enough clearance.

  7. 6inline, what ex manifold is that?
    Well given it is Knuckdusters car his answer is posted above when I asked :) but here it is again.

     

    I spent about 6 months searching around ebay.au and ebay.uk looking for a header. Finally found one on ebay.au for around 375 shipped iirc which was brand new made for an r33. I bought it not knowing if it would even fit in the engine bay and of course it didnt. It hit the fire wall so I cut it down to get it re-welded so that was ok. Then the nut on the steering arm would hit when turning the wheels so I had to grind that half way down. Despite all that bs it was definatly worth it. I havn't been on the dyno since the motor was first put in but seat of the pants feel tells me there was a pretty big improvement, id guess 20 or so whp/tq..
  8.  

    here is the video.

    I dont know but i love it,

    Actualy i dont want to run on race gaz, sur i'll go lapping but my goal is not to have 300hp, i like the idea to have injection and twincam, and stay N/A with a nissan engin. So i realy like this set up. I'll go chek on R31 skyline forums.

    He has pulled the engine since then - he did a few track days with it (on youtube too) he has gone back to L6 powered and I believe due to local classic racing rules. However he did enjoy the car when it was RB25DE powered.

     

    There are a few RB30DE powered cars here in NZ, 2 are owned by the same guy one is race car and that puts down 300rwhp (ish) it runs 50mm ITB his other car is a street version no idea on the power. I have a RB25/26 hybrid in DE with ITB however it is still some time away from getting on the road as the body is currently getting painted then I will install the wiring etc then engine.

  9. Interesting.... Your not the only person I've talked to who has had large runouts on those AZC kits.
    It might be the rotors not the kits per say - I know when I purchased some Wilwood rotors (now on a mates race car) there were run out issues so it might be just the wilwood rotors. I guess that is why AP rotors and the like cost more as maybe they have better tolerances.

     

    I found issue with getting calipers/rotor setups to clear the RS Watanabes rims also. I have now got Hi-Spec brake calipers from the UK as these are well made and have a lower profile than any other caliper I looked into. I am using the ultralite 2 pots on the rear with a custom internal drum park brake setup (would not do it again - I would now recommend just purchasing the Hi-Spec SVA calipers with separate park brake build in). I only just received my fronts this week I went for the billet 4 as these are close in spec to the FIA pot calipers ie pad/piston sizing and over all sizing of the caliper.

     

    Also the setup I have gone for is not large but larger than the normal Toy/Z31 front setup and 240sx/Z31 rear setup and smaller than the JKS/AZC 12.2 setups. I have gone this way so I could go back to 15" rim if I wanted to + I did not want to over brake the zed and put extra unsprung weight into the car. The Hi-Spec calipers are nice and light and smaller rotors also cuts down the weight. So if I have brake issues I will just add better cooling for more performance from the setup I will be running.

  10. BUMP. Did you ever use these urethane engine mounts? Feedback?
    yes I did. However the car is still in the panel shop so feedback will have to wait. I used these and one of their gearbox mounts for my RB conversion due to the interlock design.
  11. You can get NA RB headers from japan.
    Yes I know I have 3 sets of stainless steel units but they needed modifying for the S30 body (well I have 2 and won the auction for another set the other day - just waiting to hear from the seller re the collection/payment details) so looking to see if these are a different version to those that I have which are for Skylines with RB20 or RB25's in DE :)
  12. Yes I believe they fit but they don't have the circlip grooves in the side gears = you need to disassemble and machine them in + they have block in the centre that is too thick and will stop the axles from going in so this needs to be machined down also.

     

    I have not done this but this is what I believe is the case as a mate as one of the centres in his R200 long nose the mods were done by a local diff shop.

  13. That in itself is pretty awesome! I think having the exhaust on the passenger side might free up some space from the booster and the steering column and allow a lot more tube to fit in there!
    That does also depend on which side the passenger sites ;) us with the RHD would like the RB26 Style. However the engine would need to be leaned over for the RB26 style which would mean getting a Z20/Z42 bellhousing for the L6 box or would a RB bellhousing mount up ok - might have to keep an eye on this project the thing I like about this is L6 bottom end and chain drive.

     

    I have gone RB conversion for the DOHC look (as I know the L6 in NA form will produce more than enough flow and power for my purposes) so this is one of the ways I can afford a Z432 theme/concept but using a modern Nissan motor. To have a chain driven L6 with a DOHC I like the idea and I hope this project continues to shed some new light and interesting results.

     

    Hybridz is the name of the site and Hybridizing the name of game and it is game on with this concept.

     

    Those ports look large so - would the head be too large for NA setups? I think a L28 bottom end would need to increase in cc to match a head with ports like that (no idea really not a mechanic/cylinder head guy)

     

    I found a website the other night with pics of these engines (lost the link will have to check again) but they showed the cranks for these engine - very nice fully counter weighted - anybody know the specs on these and if one could be made to fit a L6 bottom end ;)

  14. they weren't factory, but they were a dealer option
    Well that is market dependant as they were factory on 260z and early 280zx here in NZ and I think the same is true for AU/OZ. Dealers here were not doing options as you state, yes there were options when ordering ie auto or manual (and in this part of the world all 240z/260z were 5 spd from the start no 4 spd for us at all), colour that was about it, all other items were factory fitted - lucky us no dealer add-on to jack up the price.
  15. put the insides from a more modern tach that is designed the more common negative coil hock up (this is what most ECU replicate) not the inductive loop from the positive side of the coil like the stock 240z/260z points tach. I believe a number have used the internals from a 280ZX with great success.

  16. All sounds right to me - AREA is only used for cooling in the braking surface after the work. After all a brakes job is thermal transfer of the work. Well this is my simple understanding of it all.

     

    In a car = engine turns thermal energy ie the burning of fuel into motion via the power stroke in the ICE. The brakes take the motion and turns that into heat via the u (coeff. of friction between the materials and the force applied) the area comes into play in allowing these to cool down quicker ready for the next application of the brake and thus allowing better motion to heat transfer of energy.

     

    As some might know after x laps on standard brakes they stop working as they are not cooling quick enough = less motion to heat (as the heat is already there) and the u can no long provide the correct balance of F and N which equals

     

    F.......Far out that was one close almost a

    N.......Nasty crash better get something the help with

    U.......underpants replacement......= get better brakes so we can put the FuN back in the equation.
