Hey guys! Im assuming theres a thread about this somewhere! :unsure: but anyways, I want to do a 5 stud conversion on my 31.. now I can score a close to free set of hubs and calipers off a R33 GTS-T series2... from what I have heard it is a possible conversion.. but im not sure about the rear? the R33 has hicas whereas the 31 doesnt!

Also, would anybody know if changing the hubs limit the possibility of me running S13 LCAs and steering knuckles?

Now on to the RB25DET! Ive got a RB25DET with 50'XXX KMS with the wiring loom and ecu.. the gearbox on my 31 atm is suitable for this engine as it came off a R33. But im not sure if I need different engine mounts and whether or not I can use the RB25's wiring loom and ecu or would I need an aftermarket setup?

Has anyone done any similar conversions? Id really like some insight as I dont have a clue on what to expect! :unsure::woot::woot:

If you want 5 stud + upgraded front brakes

You could do s13/s14 front suspension conversion, LCA/hub/knuckle/brakes etc. This allows you to run R32/R33/R34/S14/S15 calipers

For 5 stud, you could run some aftermarket alloy 5 stud hubs if you're using s13 gear, or s14 is already 5 stud.

For rear, you need to get your axles filled/redrilled 5 stud, then use R32/R33/R34/S14/S15 or redrill your standard rotors.

All of this info is over at R31 Club forum / wiki.

Lots of people have done RB25 conversions, you're best to go to R31 Club.

Also, keep in mind that assuming your car is an Aussie R31, then the rear end has nothing in common with import Skylines. The R32-34 have variations on the standard Nissan IRS design of the era, and the Aussie R31 is a solid rear axle. Nothing swaps.

To be honest, i was chatting to a nissan specialist, and he had 33 hubs on his s13... so i put the two and two together and assumed they would also fit on the 31 lol! but ive decided on something else now! :)

    • Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R. 
    • Thanks. We getting some parts along too so he will be solving the speed issue like next week so i will let you know what he came up with.   
    • 21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.
    • Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.
    • Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
