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.

    • CTIS (Central Tire Inflation System) has existed since the 80's. I'm looking into buying a Hummer H1 and they generally included it. 
    • My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
    • Fark the AFM card and Nistune, Haltech Nexus S3, DBW, cruise control, flex fuel, dis dat.  
    • It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.
    • Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!
