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.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
