Hi everyone, I'm a new owner of a Skyline R33 GTST and was hoping someone could please help.

I bought the car only three weeks ago knowing it was due for a new timing belt. We booked it in for the service yesterday with no problems and now it is buggered! It's totally fine on idle and no load but when I get under it or coming up a hill it splutters like crazy, almost sound like on the rev limiter.

Can someone tell me if this mechanic has totally ruined my car or is it a new problem unrelated to the work done?

Cheers,

Garth (excited but now sad Skyline owner)

Well of course, if it went bad straight after the work something he did likely caused it.

Timing could be wrong either cam or ignition. Sensors not plugged in correctly, coil loom as mentioned.

What's your plan?

Fix it yourself via an internet diagnosis or be normal and go back and get him to fix it?

Thanks guys, I will be taking it back Monday of course but I am hoping I can fix it for the weekend.

I played with the coil pack plug and that seemed to fix it for a bit but now its playing up again. I am going to have a look at the hot and cold side of the intake and hope that it could just be an air leak considering it only happens on boost.

If its breaking down under load most likely it will be an ig fault. But have them double check cam timing and cas timing, If the locating key on the intake camshaft has broken without them noticing they may have installed the cas one spline out. If timing is all correct with everything sounds like you've got a def ig fault if its under load.

Maybe they were a bit rough with 20yr old coil loom

this is quite possible.. or the CAS has dirty contacts (although this should cause poor running always I would think).

original mechanic needs to fix it. or if you have lost faith, find a better workshop. one that specialises in skylines. if you take a skyline to someone who is used to working on carby motors you are in for a bad time. they have to be familiar with the type of car (turbo injected) and ideally the brand (nissan) too.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
