R34 Gearbox Drama

Hey everyone.

I just recently got my new 34 GT from top secret imports in blacktown. When i test drove it before compliance it was an awesome machine. Gearbox was fine from 1st to 5th.

After waiting close to 3 weeks for compliance and rego i get the car back take it for a drive to get some petrol and on the way home changing into 4th at about 4000rpm or above no matter how hard i push the clutch into the ground it crunches in 4th and 5th.

at lower revs it pops into 4th but still crunches into 5th no matter wat. I think since compliance they have stuffed up the sychros so I have since taken the car back and they are looking into it but i thought i might do some asking around to see if anyone has had a similar problem. (tried a search nothin specific enough).

Anyways my questions are,

What could they have messed up with on compliance?

Was it just not put back together properly so the clutch doesnt release the gear properly?

and why wouldnt this affect the other 3 gears?

Anything would help give me some piece of mind.. Been nothing but a headache since i started compliance and i dont want to think i have bought a bodgey skyline after drivin it so nicely before.. Lost the car for another 4 days too :P

And may as well ask while im here.. what does this sticker mean.. its like a green clock with the 3 highlighted and some writing around it

Parking permit???

Im sure someone took it for a thrash before pickup; basically downchanging hard and snapping gears *no f*kkkkn respect for other peoples property*

Cmon how many times have we heard of mechanics and apprentices writing off cars? I know a few and the stories are all the same.

yeah sounds like it's a synchro issue.

Would they even touch the gearbox in compliancing?

Hope you sort it out

My 34 does this also, and has for the last 2 years. I don't think its a major issue so haven't worried about it too much as its not getting worse. Check out these threads on the same topic.

Possibly when they changed the gear oil at compliance,

The oil they used may be too thick, if the synchro's where abit warn the thicker the gear oil, the harder the synchros have to work to cut through the oil to mach gear speeds.

I was also told by the guy that complied my 34 to change all the fluids again due to them using poorer quality and cheaper fluids.

100% agree; use redline superlight shockproof. very light and even compatible with getrags which need an auto fluid.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
