do all jap cars have 180km/h speed limiters eg: nm35 axis , and how are they removed, do jaycar make a kit, they make about everything else ???? :cool:
No just cars intended for the Japanese domestic market. In manuals you just cut the appropriate wire but for autos you need a device such as my GReddy Speed Limiter Cut Controller ($160 roughly) which will do the job. Jaycar don't appear to make one. You can get the speed limit removed with some major re-chips or of course with an aftermarket computer.

If you are going to install a piggyback ECU, I believe that the eManage Ultimate can override it.

Did you end up getting that white Axis Alan?

Well your mate's 33 coupe is probably wire 53 but I'm sure a search in the Skyline section will confirm that. I had a quick look at the pinout diagram for Stageas (you'll find it in the DIY section under ECU) and the most likely suspect is the wire on pin 29 which is where my greddy speed cut thingy is connected. In my car I hit a wall at 180 (it could vary according to how accurate your spedo is, what size wheels and tyres etc) but since putting the whatsit on the ECU i have had 180 - 190 at the Taupo A! GP track and just over 190 at Manfield. I was looking forward to Pukekohe next month where i should have been able to get well over 220 on the back straight but unfortunately my car is no more. Have to wait til i build my next one.

i've taken mine over 180kmph (the needle just kept going)

and i dont seem to have anything attached to my ecu :(

You and me both.

I guess that the needle would have hit 195kph if there were numbers that far.

I do know that my speedo shows 7kph high out due to 18's, but could the original speedo be out 10kph?

I think that only applies to maybe R33s or newer, I know the r32 autos still work with the wire cut, 52 or 53 is the one :D green and yellow?

you hit a wall at 180 ? phsyically ? or with the computers speedo cut ...

yeah, as soon as mine used to touch the dial, it used to pull back the fuel and start shuddering like a son of a b*tch

I dont quiet get why people want to remove the speed cut on their cars.....

180 is plenty fast enough as it is(havnt even hid speed cut in mine) . Plus its bad to push it that hard and spin out top gear.

Isnt it all about how fast and how much it throws you back into your seat...

Removing speed cut is not a necessity for the road (unless you are in Germany) but it does not do any harm - you can do 180 in third and in fourth 200 is not really revving hard. BTW I don't suggest trying these speeds on public roads and not anywhere if you haven't done some basic improvements to your suspension and wheel alignment - the standard setup could have you struggling to keep it on the road at illegal speeds. It is a necessity for track days unless you like being passed by slower cars that don't have speed limiters.

      No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT

      Just cut the bottom of the guard out. It's no longer got a big duct, to a sealed box, or a restriction. It has all the cold air from outside. Also, that cai you showed looks terrible. Bends are NOT good for go gos!

      Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 🤔

      If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.
