I might be on re-runs but could a someone please tell me if its simply a matter of cutting the right wire [which is?] in an r 34 gtr to diable the 180 klm speed limiter. I Know it has been covered with regard to 32 and 33's i am just wondering if it was the same in the 34's.... cheers

i dont think you can jsut cut a wire. but can i ask why would u want to remove the 180km so badly? do you do alot of track work? or is it just a street car?

if ur planing to mod your car in the future just hook up a power fc

Yeah i agree and will get a pfc in the not too distant future, but i will wait till i can afford a few more things like injectors, turbo's etc then get it tuned hopefully just the once. Yes the idea is to track the car at qld raceway and the mt cotton hillclimb [180 not a chance there!!]

If the car is mostly stock the power fc can be installed and used with the factory map, Its just slightly tweaked versions of the standard ecu maps. Mine has been running fine on the factory map for 12 months now.

Thanks mate,

Not such a bad idea, i know if i had a pc i would want a tune straight away though!!! viscious circle!!! :blink:

just cut the wire leading to the flux capacitor

You Guys are hilarious.....and so informative!! :woot: lol. Looks like i might have to get a pfc, cause i reckon this will end up being a gee up and i will end up cutting the wrong wire!!!!!

You can do anything you want to your car - cut wire 53, use Homebrand motor oil, clean and reuse the spark plugs etc.

FFS - you've laid out plenty for this vehicle and you want to take shortcuts?? If you want to exceed 180km/h, obviously you want to use the performance that the car is capable of.

Fit and tune a PFC. The whole excersize shouldn't cost you more than $2k, of which you will recoup half of this if/when you eventually sell the PFC.

Apreciate your sentiment Gav, but lets be realistic, by-passing a 180kmh speed limiter is quite different to running a car on homebrand oil, and the car is essentially stock so i feel Nissan's computer is probably more than capable of doing the job sufficiently well. If there are no negatives i.e Hicas shutdown, then i would be happy to cut a wire. so mate if you can help, that would be great.... :woot:

I don't have a wiring diagram for a BNR34, but I would say there's a better than 50/50 chance that the signals from that wire are used for more than just the speedcut function in the CPU.

UAS has an HKS Speed Limit Defender advertised on their site for $280.

Give that a go if you don't want to commit to a PFC and tune at this stage.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
