Hey all,

Have a 1997 R33 GTR, making 239 RWKW with standard computer. Am quite happy with that for the moment and want to keep the factory computer for a while. Unfortunately was hitting the speed limiter half way down the straights at Sandown.

Anyone know how or who can cheaply remove 180km speed limiter in r33 GTR while retaining the factory computer????

Cheers,

Luke.

ok have you ever taken a look at the computer? its at the passanger side

ive never tried this myself...since ive never owned an R33....

but apparently there is a wire to the Computer labelled No#53...

cutting this wire....taping it up would disable the speed restrictor....

cutting any of the wires...you could always join it back up...so if i were you, id give that a shot....

why do you need to remove it? because how are you going to test this out?

this would be the "cheapest" way without modding the ecu

make sure you let us know how you go on this.... should this work, ill post it up on the DIY section for future reference. Im pretty sure we need this one in there

easy and safest way is either

HKS - SLD - Speed limit defender

or

APEXI - RSM

either one will remove the limiter, although I would go the apexi, at least it will give you a few other functions you might find useful on a track.

That's safe and nearly $500 retail for the Apexi unit :(

Wire #53 is commonly known as been able to be cut (according to the SkylinesDownUnder I believe), I never tried it personally as if you have an aftermarket ECU you won't need to do that trick :)

cutting 1 wire is not butchering the car, yo can EASILY join it back up :P

ermm both you guys i dunno if you read his question...... he asked for the CHEAPEST way possible..........

hes "happy with everything" for now.......so he didnt really ask for jibber and jabber or gidgets and gadjets....

i think this is the most efficient way to suit his needs

do you know if this will work for a gtst is it the same wire .... i have heard of this before and was told that #53 wire is the out put to the ignition module when the computer switchs it to earth the ignition is disabled if this is true its a verry easy cheep and safe way of disabling speed limiter im sure you have to cut more than one wire to install one of the hks or apexi units listed above so why would this method be dodgy

If you are in Melb I have stock ECU with a Speed limiter over ride connected to it already. For you to look at. This was installed by AVO.

This should give you an idea of what is required.

the apexi rsm can be had for $300 direct from the usa..

and i thought that was really cheap.. 300 bux is nothing.

pivot speedmeters are pretty cheap and will remove limiter, cutting no53 is obviously the cheapest but you guys with autos better do a search cause i think its a no no.

I've heard you can melt the limiters by travelling at the max speed (this being 180k) for at least 5 minutes at a stretch...the fun part would be finding a stretch of road that is suitable for 5 mins worth of flat out driving at 180Km/h...That overides them without having to buy a limiter defence cut thing.

Or you can do that on a dyno :(

I heard this from many people not just a few of em and a few people who have actually succeeded in doing so. So its worth giving a try i guess, just run your boost on low and gradually make your way up to the speed ona dyno and leave it there for as long as needed.

Don't know how reliable this is since i havnt done it myself...but worth a try like i said....

i think it is the same wire. have a look at the ECU.. apparently the R34 is wire 29# or something but 32 and 33 has the same.

yes i recon... people are forgetting how Stereos, speakers, Alarms, Tachos, immobilisers are installed.....

no body solders things anymore.... its just snip snip.... and electrical tape it shut....

i think its worth a try... and if its no good.... just tape it back up...

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !

      Yeah man, absolutely. You can try pushing me all the way in swapping the R34 for an E9x M3

      By GTSBoy · Posted

      It's almost certainly going to be some amount of pads compound transfer onto the rotors. It will probably go away after you've run them for a bit. If not, pull it all out, lightly sand the rotors, scuff the pads, and rebed.
