ok, so my car officially has no rev limiter, it goes all the way just past 8 grand (before i back off cos im scared she'll blow!). im 99% certain the taco is accurate as i hooked up a SnapOn diagnostic comp and it read the same. also went for a drive sunday and there doesn't appear to be a speed limiter. just wonderin if anyone has experianced this and they know why.

second thing, little while back went for a massive 1 and a half hour drive about an 1hr of hard driving and now im gettin a metal on metal sound like a scrap, periodically. sounds like its coming from the front left hand wheel. Possible break issue? i haven't experianced any lack of performance in any area since the noise started. so i got clues. any help would be great guys.

My Old R33 had a HKS F con V Pro piggy back type ECU. At one stage I removed the F Con and just ran off what I thought was a factory ECU. Anyway it turned out that that ECU had no rev limiter or speed cut either and had obviously been modifed. I'm guessing yours had been modified the same for what ever reasons.

The metal on metal noise could be brakes, could be faulty shock absorber, could be your rim scrubbing on your coil over etc ... could be anything reall.y best thing to do would pull your wheel off and check for scrape marks as metal tends to leave an obvious mark.

the metal on metal sound is you running into the guard rails because you cant handle the extra rpm and speed.

Get a clue!

hhahah

gee thanks for that i'll keep it in mind..... yeah i was thinkin maybe the turbo as well, cos when i hooked up the manual boost controller to the actuater line there was a bit of oil run. now as far as i know with my limited knowledge, having oil in the turbo might not be best sign of a healthy turbo. But then again as i said before, haven't lost any boost what so eva, gonna get the brakes done early next week and see what happens. also yeah checked the ECU its factory doesn't look like its been modified at all, is there anythin to look for?

otherwise cheers at least i know im not alone.

i had a similer sound coming from my 32 a while ago, turned out to be a very thing peice of metal on my brake pads that gently rubs on the discs basiclly lets u kno ur pads are getting low. they call em squiller pads or sumthing.

an concerning ur ecu they may have just cut the wires, i kno The wire is yellow/green with a silver trace is the speed limiter. check this website out an read a few things on there u may be able to locate the problem.

Sounds like your brakes are prolly just getting low after the thrash. If you look thru the wheel you should be able to see the outer pad. The bit between the backing and the disc is the brake material. Normally if a turbo is going you will hear a shrill noise when you come onto boost (terrible noise). They do tens of thousands of RPM so its too fast to sound like a scraping noise.

Hope i helped.

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
