And you'll kill another one. There isn't any difference in strength, the synchros are just revised slightly for better shifting. There is bugger all difference between the boxes really, I don't know why Nissan even bothered. About 10 parts were changed.

Ok good to know anyone know what the go to brand is for gearsets these days ? As it's still street driven would be better just doing 1st to 3rd ? And keep 5th as is ?

Ps if anyone has a second hand sequential I may been interested !!

You are correct, a loosely thrown around interval is 5000km, but that is largely dependant on the operator. Someone who is very skilled at changing gears in an H pattern dog box will cause little to n

and are also apparently not very good for an over $20k box according to the UK guys. For more info Tim at Special Vehicle Services in the UK is actually how you obtain one, not through Quaife as

Yeah that's the go and what I still use in the 33. If you get the 3 speed kit with uprated input shaft it ends up being strengthened 1st - 4th gears with a standard 5th, as the input shaft is essentia

For a street car would you guys recommend the 3 gear set instead of 5 gears? I don't like how the 5th gear is shorter, as-is the engine turns ~3000 RPM around 130 kph.

The OS Giken 5th is more for circuit racing being shorter.

So an Os gearset over a Par set is the recommendation? 

Probably a dumb question but looking at my attachment which one should I order? The heavy duty input shaft or the holinger type?

Cheers

Edit: I don't have a clutch yet so will probably go with the Holinger type and an R3C

OS Giken gearsets are now confirmed in stock again at RHDjapan if anyone is still looking.

A few key points I'll mention about those wanting a Giken gearset which are usually overlooked. There was a reason I posted this - they have been very hard to get and RHD seems to be the pick for supply. They are in stock now, but next shipment is September or October if you miss out. Also those Greenline prices will absolutely not be updated, their site is terrible for this. This is about the cost breakdown of doing a box just for you guys thinking of doing one -

The kit with input / no 5th is about $4.3k and with 5th about $5k before tax or shipping. With Covid-19 at the moment means no EMS from Japan either, so only shipping option will be by international courier = expensive. Usually DHL, which means you absolutely will pay GST as DHL are pricks for always picking this up.

If you've got an old box budget about $1000 for series 3 upgrade parts and about a 1 - 2 month wait. Want a centre plate (recommended) ? Budget another $1200 - $1500. Want a GM / Holinger 26t spline upgrade ? Special order input shaft, and custom machining out of your existing gearbox front cover another 3.5mm diameter to fit it. Cost $500+

Can't get box in and out of car yourself ? $500 from workshop for box out. Same again for box back in, $500. Can't assemble gearset yourself ? Minimum $2k box strip and reassembly.

Getting pretty close to a $10k box now, without a clutch.

....and they do break.

I'm in a bit of a interesting situation at the moment as well, I currently have a ppg 5sp s/c dog box in bits waiting on parts from ppg which may be upto a 3 month wait, so I'm torn on do I sell it as is or do I wait and fix it, out of all the options par seems to be best local option at the moment.

my questions is should I sell the gearset and buy something new or do I wait and fix it and give someone a good deal?

poor assembly, caused me to have shifting issues with the shifter coming out of the trans during high load shifts and even miss selected a gear a couple time when the shifter came out.. I'm lucky I didn't fold my motor in half

yeah it was a shame as I only did 500km's before I decided to pull it and check it out luckily as it would have caused more damage. I'm torn between building a o/s syncro box, and this dog box as I love the whine and dog engagement as when you get a good shift its just awesome at how fast and direct it is.

That won't cause flames as a sequential box is always going to be superior on the circuit, but that's not necessarily what we're all talking about is it ? It's a far too simplistic view, as not everyone wants a Sequential or dog box.

Some people want helical gears, some straight cut gears. Some want synchro, some want dog engagement. But some people want an H pattern, or any combination of the mentioned configurations in a transmission. Driving an H pattern, synchro box on street is always going to be the easiest box to operate. I happen to like straight cut gears and dog boxes, but I like H pattern too.

Albins and Holinger have been proven to make quality gear, but being sequential doesn't automatically mean stronger by definition. I hope your not under the impression you are going to spend $25k - $30k on a box and it be indestructible. The sequentials are not a set and forget fix, require regular teardowns like any dog engagement, and they also can break just like any other box. A sequential would be the last thing I would want, or need, on a mainly street driven car.

Rebuild it for sure.

Ok... 

So why does it seem hard to get details on the cost to maintain the dog box's ?

 

I read very mixed info of needing new dogs every 5k, some to most gears seem to have dogs built in, so your buying a full gear. 

Almost no on advertises the cost of gears and you feel like your wasting peoples time to call when you are in options mode. 

 

A real street car in my mind is going to do 10,000k a year and your looking at one or two gearbox overhauls ?  At xx price ?

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
