I've got a Nismo one in my R33 GTSt, but i wouldn't really say it's a "heaps" shorter throw. It did make it notchier but feels more solid...

The throw was only shortened slightly but I like the way it feels now - still makes you feel you're doing something when slamming into the next gear :) So I'm sorta agreeing with Ash's comment/opinion...

I think the Nismo GTR short shift reduces the throw by a lot more compared to the GTSt model...

Comparison of a short shifter gear lever and a standard R33GTST gear lever.

1903Shifter_Comparison_Small.jpg

As you can see in the above comparison, all a short shifter really is just a gearstick with the pivot point moved upwards. This means that you get the same movement of the shift linkage (in the gearbox) for a shorter movement of the gear knob. That has 3 effects;

1. The gear knob moves less (back & forward and side to side) for the gear change. This is not a bad thing as your hand moves a shorter distance from the steering wheel, so you spend less time one hand steering.

2. A higher level of force is required on the gear knob (by your hand) as there is less leverage. This higher level of force can manifest itself in more feeling through your hand/fingers for the gear change. Provided you are not a weakling, there is no real down side to this.

3. If you move the gear knob at the same speed, the gear linkage moves faster, hence tries to change gear faster. This can be a problem, because the synchronisers may not be able to move at this faster speed. Hence you can get crunching as the gear tries to engage before the synchroniser has had time to align the meshing. This is an often quoted problem with short shifters, one that is easily overcome by slightly reducing the speed of movement of the gear knob.

The trick with a short shifter is to know what it does and use it to your advantage. Don’t fall for the fallacy that you can change gear faster with a short shifter, because the truth is you can only ever change gear as fast as the gearbox (synchronisers) will allow.

:D cheers :wub:

Ive heard these can damage GTR gearboxes due to the mesh being different to GTST boxes? is that right?.....any first hand experience?

100% BS

Internally an R32/33GTR gearbox is the same as an R33GTST gearbox, other than the take off on the output shaft for the transfer case of course.

:D cheers :wub:

im running a r33 gearbox in my r32. It actually has a std gearshift lever that has been cut and welded.

i cant remember where it had been cut/rewelded, but i dont know if its a shorter shift or not. The gearknob height is shorter though.

If it's been chopped down, then it will seem like a shorter shift. I'd liken that to chopping springs in a car though, bit of a hack job. =-[

If you imagine your gearstick three times as long, the top of it would travel much further... if you reduce it, then you are moving the top a shorter distance, but i'd imagine that it's uncomfortable to have to grab lower down to get it.

And to the above guy with the Nismo shifter... there are two.. one is a "solid shifter", which as you felt, makes shifting feel more direct. It has a 10% shorter throw. Nismo make a "quick shifter" which apparently is 25% less throw.

Thanks, SK, for the background on the mechanics of it!

I really would like to find a proper shorter shifting leaver... It becomes a short shifter in that the length is shorter... I dont want to do a hack cut job... and installing a short shifter stick will reduce the throw, but not the length of the damn leaver....

Bought one off ebay about 4 years ago, to much noise through it from gearbox, so cut the shifter below the solid section and same place below the rubber mounting on the standard one and tig welded to rubber mounted top half onto the short shifter bottom. The noise disappeared and due to the rubber mount I got a bit of give in the shifter which made it feel great.

Only thing I noticed is after a few years of driving with it, 3rd and 5th gear started to get a bit crunchy if changing to fast.

      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

      Duncan's V37.......race car?

      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.
