hi

the car is a R33gtst s1. i hear the noise when i drive slowly (straight and around corners), if im slowing down, and have notived it more if im turning left on a hill (at an intersection). i dont think its the suspension as the car has new coilovers and the sound is still there. the previouse owner said the noise was the Hduty clutch going on and off. i have jacket the car up, put it in nuteral with the handbrake off and rotated the back wheels and didnt notice much play (both wheels moved together). i havent done the diff oil yet so ill be doing that soon. the nuts on the wheels are tight so its not that (read in a diffrent thread that loose nuts cause noise). anyone have anything else i can try before i take it to a work shop and them say " *cha ching* yeah mate u have to buy all this un-nessasary crap and that may not fix the problem"

thanks in advance,

Aif

does the car have an lightweight flywheel aswell?

my 33 has a twin plate clutch and lightweight flywheel, accelerating under 2000rpm the car makes a rattling noise which sounds like its comming from the gearbox, the previous owner has said that its just the flywheel being to light causing the gears to rattle or something, seems consistent with other skyline owners with aftermarket clutch and flywheel, they all say the same thing, if this is what it is its nothing to worry about

i may have read wrong but you havent even described what kind of noise and where you think its coming from. abit more precise and im sure you'll get a helpfull answer.

i have a lightened flywheel and it makes a "gara gara" low rattle noise at low revs. do yo have a solid short shifter? is it grinding or clunking noise? coming from the front, gbox, or back? could be any thing or something silly as something in your glove box...lol

the noise sounds like a clunky rattle *CLUNK CLunk clunk* from the back left of the car, it sounded like a shagged shockie but i got coilovers and the noise is still there. and i get it if im accelerating and then let go of the throttle *clunk*

i dont know if the clutch is a hduty clutch with a lightened fly wheel (is there an easy way to check other then opening the gearbox?), because it felt like the guy i bought the car from was telling me crap to cover what this noise might be.

i have a stock shifter. i have emptied the car inc. the partial tray, boot linings and spar tyre and the noise is still coming from the back.

i hope this helps you guys help me :/

Have you checked the drive shafts / half shafts going to the wheels?

I get a clunk on/off acceleration and when changing gears and there is a little bit of slack somewhere near the CV joints there.

    • Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄  
    • From everything I’ve heard you’ll be waiting a long time for  the parts to arrive 
    • Have you looked at the workshop manual?
    • Hmm. I've gotten pretty good outcomes from talking to them about things that I've had go wrong or ideas for improvement. Have had a lot to say about the R32 FUCAs, and they have sent out some replacement parts for those, gratis, on a couple of occasions. Mind you, I have bought a couple hundreds of $ of replacement rod ends for them too!
    • I have a r34 sedan 1999 manual converted need some help with my speedometer it only reads upto 98km and then stops currently still running the auto cluster any easy fixes no speedo drive is connected yet, if someone has a video for wiring up the manual speedo sensor with the auto cluster please send through
