Lots of negative here, if you don't like a sequential then fine but plenty of race pros prefer them and when watching in car videos you can see why. Depending on driver skill then the syncros will  be a serviceable item just like the dogs are in a dog box.

What has a H pattern got anything to do with it, all depends on the driver. With a dog box the shifts have to be hard and fast as the video above showed, with a syncro box it's easier on the syncros if the shift is made a bit slower which can be done using that sequential conversion. Drivers bang through shifts on a H pattern box all the time, the syncros don't care which pattern the shifter is.

Too much bandwagoning and not enough thinking going on here.

Either way you have to wait for the synchro’s.... well to match speed.

Sick. So you have a mad looking shifter that goes backwards and forwards.... slowly. 

You cant set up a fancy nob to ignition cut for a quick change like a real sequential box.... so what’s the point. Well I suppose you could but the shift won’t be any quicker because of the synchro’s. *ignition cut..... cutting..... cutting...sweet they’re matched now”. To do that you’ll need a fancy nob ($1000-$1600 depending on what one you choose) and an ECU that can do that so that rules out a Power FC.

“Farrrrkk, you got a sequential bro?”

”Nah man, still a factory box but it looks like I do. Sick hey!. Can you like my car on Insta and Facetube?”

?.

Take the money and put something decent on the car! It’s junk and belongs in the dumpster!

 

Sequential would be rubbish in traffic but for a  bit of track time for someone who likes a sequential this Bremer shifter makes a lot of sense. A dog box sequential is something else again, in outlay and in use, it certainly would be more awkward to use in traffic. Don't know about Nissan boxes but for Tremecs there are shift enhancements available including carbon fibre syncro rings so box life with them should be good. 

There is nothing fake here, it's an option which would make sense for some.

Ikeya Formula have been doing this for years. Presumably you still need to use the clutch like you do with the Ikeya one

and they're shit.. that sequential shifter is also shit.. you forget to clutch and boom!

A proper sequential box, with strain gauge to cut ignition/rpm and/or shut your TB via DBW is the only way.

You can't just throw loads of RPM and torque in between gears, even DSG cuts torque via a torque management strategy - thus the farts and pops.

Just because you have a sequential shift like this one does not mean the car has to be driven like it's a big dollar race box, it can be shifted at the same speed as usual. Sure shifting will require a bit of learning but so does double declutching  which plenty of drivers can't do well yet still manage to do decent times without wrecking gearboxes. A strain gauge setup could be fitted but I don't think that anyone is claiming  that for a full on race use this is the best shifter.

Yet to see any coherent argument that this sequential would not suit someone who particularly wants a sequential shift but realises this one's limitations. Because it will work within those limitations.

Sequential shift, but you still need to use the clutch and make sure you lift off the accelerator... quite pointless and being Nissan, the FS5W30A gearset, they don't like to be shifted fast and at super high RPM.

All these negative comments I could understand if you were going from an actual sequential gearbox with all the bells and whistes, to a standard box with this kit on it.

Anyone who is only used to the ol' H-pattern on the track is still going to have clutch on accel off muscle memory and an idea of their rev range, unless they are literally retarded.

The benefits I can see are: 

  • the shifter location, i.e. closer to the steering wheel for those who aren't sick leb dream boats that drive with one hand on the gearknob at all times for that phallic sensation.
  • reinforces the practice of downshifting through the gears, rather than say from 4 to 2,
  • minimises the memory requirement of the current gear, especially when you're mixing it up, trying 2nd instead of 3rd at a slower corner to keep the revs up for example, and the gearknob is some 10 to 15cm south west of where you thought it was

of course all this still requires the driver to be actively thinking about what they're doing, which to be quite honest, that's literally your one job while driving, is to think about driving.

So for my shitty track car worth <$5k am I going to spend $20+k on a sequential? hell no, $1.5k on a lever? much more likely

Hi all, thread revamp 

Im looking to buy one of the new Speedtek dog gearsets (i know the history) and was wondering if one of the sequential conversions above would work, noting the concerns re normal syncros.

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
