Hi all

 

what short shifter do you use on your skykine r34?

 

my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues

 

would in your view short shifter screw this up?

 

people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?

Don't do it if your gearbox box has already having syncro issues.

The short hifter will put a greater load on them.

If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock.

In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox.

Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts

Because you're effectively rushing the shift and forcing it to go in - with greater leverage against parts that don't _want_ to go together. Short shift = forcing the gear in harder.

Also Redline Heavy Shockproof actively says not to use it in anything with Synchros.
Well, it says "not recommended" which is basically as far as anyone will ever say in a product statement to "Do not use"

Generally the Redline makes the gearbox feel great... until it fails faster.

Throw between gears are so much that is getting annoying. I have pro short shifter on my mx5 and e36 and love it . Skyline is getting unbearable 

 

would syncro issues and short shifter is no no? Anyone mind explaining a little on why before i buy cube

Throws on the FS5R30A in most Nissans of this era are actually quite short and direct compared to any remotely modern BMW with the S6-53 transmission. Those things have throws a mile long with rubbery vague everything. Synchro issues combined with a short shifter is just going to break everything even faster.

How much does the shifter move when the car is in gear with the engine off? If it is more than about 1cm you need to replace your shifter bush.

Your shifts will just get crunchier, not faster, with a short shifter unless you also rebuild the whole box

Way more than 1cm. Appreciate the advice maybe I try changing the bushing first

Start by replacing the bushing and shifter cup. Two plastic pieces in the OEM shift mechanism that can wear out and cause these problems. It's like 15 USD from Amayama before shipping. You can replace with aftermarket brass bushings but personally I was fine with OEM. The stock shifter working properly doesn't feel like there's any real problems with it.

      Mistakes were made, my R34 Story

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
