Hey so I recently got a 25bigbox into my r32 no speedo drive yet but the hole is covered so oil ain't pissin out everywhere but this strange thing is occurring I can change 1-5 perfectly fine  no crunches etc as it's a brand new reco box but changing from 4th to 5th it's like it just stays in 4th like 5th doesnt even exist. I'll push in clutch smoothly change from.4th to 5th and the rpm stays pretty much exactly the same like its still in 4th gear. Any ideas????

Take it back to the reco merchant who built it and ask him nicely to fix it (ie install 5th gear selector fork) I have found taking my 6 foot 4 110kg son with me on these missions gets fast positive action.

Well it depends on how fast you are going.  At low speeds the change in revs will be minor. You need to be more precise. When you say revs stay "pretty much exactly the same" are they in fact exactly the same or is there a small drop? Try it at a higher speed (in an appropriate setting) and then also change down quickly and see if the revs rise.

Duplicate threads merged, (because I think both answers are right!). First make certain it is not selecting 5th (ie, at freeway speeds are you sure the revs are identical when you change), if it is not selecting 5th it is box out and get them to fix whatever part of gearbox magic they didn't put together correctly.....

When the car is off, and you move it through all 5 gears (+r) does it make the same clunking noises into each gear? If there is no noise or resistance into 5th that is a pretty good sign something is wrong internally...

I am having a very hard time working out how this is possible.

4th gear on same selector fork as 3rd gear. Right? The user can change from 3rd into 4th. Right? Presumably, can change out of 4th and back into 3rd, right? Or even go down to 1st or 2nd? Right? So, gearbox is acting perfectly in the lower 4 gears. Right?

So, I posit to you, that if you try to change to 5th, you move the selector out of 4th.....it should be in bloody neutral. Not 4th!!!!!!!!!!!!!!!

The shenanigans going on inside this box would appear to be larger than "staying in 4th when trying to change to 5th", because that doesn't sound possible.

agreed, seems almost magical . or the gear ration in 5th is the same as 4th, which is ridiculous but makes more sense than it somehow selecting 4th again...

      Should I use rust converter on this?

      By Murray_Calavera · Posted

      The easiest option might be to just spray a bunch of fish oil in there.  At least that way you can feel like you've done something while you continue to ignore it

      WTB noltec r32 front upper (camber) arms

      By GTSBoy · Posted

      I'm firmly on the "zero compliance is good compliance" for FUCAs. I'd be looking to solid metal joints even if the primary reason for having them is because they facilitate the twist in the arm. I have never been more happy with the way the front suspension behaves than I have since I got rid of the FUCA bushes. Even the thin little (short lived) poly bushes in the Whiteline adjustables have too much compliance for my liking. It probably won't be long before I have sphericals nearly everywhere, probably including both top and bottom arms in the rear, and I'll start complaining about the increased costs for dental work. But I will be enjoying the driving more, I'm sure.

      Plus, you'll get great experience in bedding in pads!

      By Matvei27 · Posted

      I have offset Nismo brackets so the fact the gktechs can pivot is less important to me. I have 170mm JIC arms with bushings - but they provide no adjustment and I'm not sure whiteline eccentric bushings will fit them (I don't want to ruin the bushings currently in them to find out). Ideally I want something with bushings + adjustment; hence why I'd like to find a pair of these. Unfortunately they aren't easy to find.

      @Vee37 How much do you really care about finding these pads again? If your pads are quiet, work well and produce minimal dust, really isn't that enough? If you are set on finding the exact pads again, I suppose I'd do something like this -  Visit your local Jax, find out what brand of pads they carry. If the Jax workshop you previously went to had the pads on the shelf, then you can almost guarantee it will be of said brand.   I'm guessing you don't have the receipt for the previous work and pads. Can you visit a Jax workshop and see if they can look up your previous job to see what pads were fitted?  Still no luck? Put your stalker hat on, find the staff that used to work at the Jax store and ask them. Talk to local workshops, try to find out where the mechanics went to. Talk to Jax workshops, maybe they relocated to another workshop. When it comes to mechanics, its a small world. You'd be surprised how easy it is to track someone down. If these ideas don't work, shit will start getting crazy very quickly.... You could find out every brand and model of pad that fits that car... and try them individually ticking each off the list if it wasn't the one you were looking for.... If you go down this path your going to want to learn how to swap pads yourself, it is very easy, takes minimal tools and space. If you have room to park the car you have room to swap the pads. Plus you have the advantage of making sure all the brake hardware goes back in so they won't squeal!
