Hey guys just wondering if anyone knows the interchangeability of 32 parts to 34, e.g coilovers, turbo setup, swaybars etc? I think i remember someone saying 32 and 34 are the same in coilovers but 33 is different. any help appreciated

If you are talking about the GTRs, most engine parts are interchangable, since they all uses pretty much the same engine component.

But suspension wise, I dont think that would be the case. R34 coilover will not fit in a R32

That's exactly what I've been praying for during my hours of vain research online. I am in the process of upgrading my R32 slowly with various parts and it would make things a hell of a lot easier if I had access to such a database because using parts from other skylines is a little bit tricky.

e.g. My R32 is a gts25 coupe auto. (don't ask me why auto I have very good reasons for that :D)

The box is screwed, the diff is screwed, the engine needs a little freshen up. It currently has the RE5RO1A box (also present in the nissan glorias mated to the V6). They are apparenly weaker than the 4-speed boxes because it is essentially the same box with internals shrunk to fit an extra gear (like the S-15 6-speed boxes suposedly weaker than the previous 5-speed box).

So I am currently eyeing a 1998 R33 RB25DET auto gearbox + driveshaft+shifter+console but I don't know if it'll match the R32 in overall dimensions (speaking of the driveline not the interior bits). I also wonder if the gearbox computers work independently using signals from the engine ECU because I'm sure I would need to swap that also but I don't know how much fiddling I would need to do to match it with the current ECU or if I can even get away with using the current gearbox ECU to control the later R33 gearbox. I know it'd be easier using a R32 turbo auto box but most of them have too many km's on them or have been thrashed or a combination of both (the R33 box I mentioned above came out at 59,000 kms and should therefore be absolutely mint).

This leads to driveshaft to different diffs matching (no idea what's interchangeable between different skyline or other nissan models). The only thing I know for sure in this department is that my half shafts are a 5X1 bold pattern so that narrows things down a little. But this is surely the more simple upgrade assuming I just need to find a LSD from a turbo R33 auto with the 5x1 bolt pattern.

Then I'd like to sort out the rough running of the engine and maybe swap to a bigger block (e.g. RB30) or even just a more recent one (R33/R34 RB25 N/A block?) but I don't know what matches with regards to the oil and water galleries and also internals.

I just went ahead with R34 extractors and front pipe hoping the ports will match (not sure because of the R34's NEO head so once again it's fingers crossed) and I am receiving these goods on Sunday.

Finally, I am waiting on a pair of R32 GTR front struts (was told the fronts fit other R32's and I have a 5 stud conversion kit with the big brakes all rebuilt and painted). As I am also getting some rims next week I wanted to have the suspension setup a little nicer hence the GTR struts hoping it'll sit much nicer but I still don't know how to handle the rear struts (was told by the same guy GTR rear struts DO NOT fit other 2WD skylines -only the fronts-). Which brings me to thinking about upgrading using R33 or R34 factory rear strut combinations (e.g. R33 coupe turbo uprights or R34 coupe turbo uprights 2WD of course or a combination of one model's uprights with the other model's springs, or even use my factory struts but fit springs from a later model to drop the ride just slightly to match the front ride height assuming the front GTR struts will indeed bring the ride slightly lower).

So many questions with difficulties sourcing the answers.

Because there are many aspects covered here, it is hard to decide which section to post it under but since you mentioned the great idea of having a compatibility database in this thread, I put this in here but will also post it elsewhere on a new thread. I think if everyone who has a little experience with such matters chips in, we can slowly build such a database for all of us to refer to and it should have a dedicated sub-forum for quick access. Then the sky's the limit, we can all add information as we go with modifications and keep building the faq that way.

Should I fail to find answers with this post and therefore decide to go ahead with one particular set of options mentioned above, I will post my findings afterwards. I want to get this done by the end of the month, leaving the engine work to last.

Peace

Oh, and I forgot to mention swap bars also. e.g. would GTR swaybars fit the GTST hubs straightforward, and if not, would it be worth upgrading to GTST sway bars or even ones form later models or other cars such as sylvias etc... that would bolt on. Which cars actually use the same swaybar dimensions and fitment and which ones would represent a worthwhile upgrade i.e. increased stiffness and handling performance through bigger diameter. blah...

Done...for now

and r32 gtr rears dont fit because they use a U shaped bracket on the bottom whereas the gtst uses an eye... this can be changed if you really want.. but there are plenty of coilovers around for both models.

      Front LSD Quaife , how streetable ?- QDF3L Owners

      By joshuaho96 · Posted

      Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?

      The FD RX7 is the best looking 90's JDM car

      By Kinkstaah · Posted

      in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.

      I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.

      If they just called it the "Mazda Tiffany", it would have been spot on.

      Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
