That's weird man. You can buy the caps from a Nissan dealership. The shifters work on RB20 boxes as well as RB25's. The only difference between the two is the cap size is bigger on RB25 and GTR boxes, and the retaining bolts are longer on RB25/GTR.

The caps are only a few bucks so it's worth trying. You will need to give it a bit of pressure to fit them on as well. I placed the cap on the ground and pushed the shifter into the cap using a small amount of body weight.

I had to swap mine from the RB20 box to the RB25 when I made the change, and the ball was the same size between the two. Only the cap size differed.

Yeah ditto on all of that. While mine was a C's shifter though, the principles should be the same.. ran it on my RB20 box and then the 25t box.

I would also maybe find a short bit of pipe that fits nicely around the shifter bush as if you give it too much force to get the ball in you can destroy the nylon bush pretty quickly.. something around the outside of it should help keep it in one piece.

i was about to buy a nismo short shifter for my r33 GTST but heard they can cause long term problems with the gearbox. Grinding etc. Is this true?

My brother has an 07 WRX with the (factory option however) STI Short Shift. It makes quite a difference in feel.

First I've heard.

I've had mine for 2 years with no ill effects so far.

Hey all,

Searched the forums and this is as close as I have come to my problem.

I have a Nismo shifter in a 33gstst. For some reason whenever I am giving it a squirt and hitting around 6krpm or above and change from 2nd to 3rd, or 3rd to 4th the shifter seems to pop out of its housing? And I cannot find any gears? The shift distance greatly increases (like factory) and the car pretty much becomes undrive-able.

This has happened on a couple of occasions. The first time I took it to my mechanic and he just said the nylon bush needed replacing/repairing and it shouldn't happen again. Around 3 months later it has happened again. This time I took it apart myself, inspected and re-seated everything in hope it would be fixed, however no avail.

Is this a common problem? Can anyone point me in the right direction to know how to fix this? Preferably permanently.

Cheers,

Greg

It depends on how you drive. You can punish your gearbox with the standard shifter as well, its just that the sort shifter makes it easier to change gears more quickly. Lots of very fast changes will eventually take their toll. Dont drive like a dick and you'll be fine. :P

Great background info mate, however I am after a solution this doesn't answer my question.

Anyone know how to fix?

Dude did you see the QUOTE (Mattw_83 @ 15 Mar 2009, 12:12 PM) at the top? I wasnt answering your question...

But - have you got the correct internal circlip on yours? It shouldn't be able to pop out. IIRC it holds down a nylon "cup" that the ball on the shifter sits in.

if your talking about the half cup that the shifter sits in inside the gearbox housing and the plastic ring that locks the shifter in, try twisting the shifter and half to discover that the bottom half threads into the top half my idiot friend cut the plastic retainer ring to fit it over the ball end of the shifter instead of twisting it in half.

Mr Kotter, I did not see any circlip - maybe mines missing? I missed your quote earlier sorry mate.

Sukai, I will have another look at this when I get it off again.

Does anyone know why this happens? Poor shifter? I would have thought better of Nismo.

Thanks for the info guys, appreciated.

I also have this problem

I have a apparent r33 stock shifter that does the same as what Skydragon is having issues with.

Also have a stock r32 and stock s13 shifter available

The plastic cap on the end of the "r33" shifter is much larger and doesnt fit into the bottom of the s13 and r32 shifters...

I did a r33 box convo and never got a shifter with it :ermm:

Ok I havent got the r32 shifter handy (its bolted into the box and its cold outside, cbf pulling it out)

But this is what the r33 shifter looks like.

It seems the shaft that the smaller ball and nylon cup is too short for the box.

Its a good 10mm shorter than the r32 item.

The nylon cup from the r33 shifter also doesnt fit into the r32 shifter.

Can anymore confirm that its the correct shifter?

Greets man.

That doesn't look like a short shifter. The throw should be longer than what I'm seeing.

The short shifter setup works by placing a bushing into the seat and extending the throw, compensating for the bush. The shifter sits on top of the bush. A cap is used to retain the shifter because it no longer sits inside the seat and cannot be retained by the factory circlip, it's also bolted down using C clamps.

The 20 box uses the same lever as the 25, the only difference being that the 20 box uses a smaller nylon cap, and the 25 uses a larger cap. The GT-R box uses the same cap and lever as the 25.

Yer I know its not a short shifter, but I was having the same problem with the plastic cup not seating properly and ripping the shifter out of the selector.

Also need a opinion if its actually a r33 shifter, not something else...

The nylon cup thing of that shifter pictured %100 does not fit onto the end of my R32 shifter :D

Replace the nylon cap, they're only about $5 from Nissan.

R33 and R32 shifters are the same.

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
