So i think its related...

When i turn on the car none of the gauges or power options work at all until i rev the car over like 1500 rpms... its also running really rough and I took it for a drive and when u get past like quarter pedal or give it any kinda gas around 3000 it sputters pretty bad and backfires alot. no power it seems, i didnt push it really hard to find out tho. just turned around after like a block and came back home. i think my alternator is almost pooched because i boosted it this year with a completely dead battery that wont hold a charge and drove it for awhile like a week ago it seemed to run really good besides not able to keep the volts up, the altanator was already getting weak. Yesterday i just put a battery in from my beater an 88 K car to get it running to drive... and thats when the gauges wouldnt come on and this problem started. Its in an R32 GTR

Any help would be great!

thanks

Yeah mate, chuck a meter across your alternator and see what voltage it's putting out. Should be between 13 and 15 volts for normal charge. If it's below that it could be your whole alternator (brushes etc) or just your voltage stabilizer (which is like a $70 part).

    • Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.
    • The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.
    • Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?
    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
