So i have a 97 r33 gts-4 (n/a), rather then getting a mechanic to service my car, im going to attempt to do it myself.

What spark plugs do you guys recommend i get? Also any other info about servicing this car would be appreciated, im kinda new to these 90s japanese sports cars, but im trying to learn =D

That's 1.1mm gap. Unless you have new coils, get plugs without the "-11" at the end (meaning you get 0.8mm gapped plugs)

Get BCPR6ES, they're like $3 each.

Yeah you can run 5 heat range, I just find it easier to grab 6 range as they're everywhere (and I buy two sets, for both my cars). The car is 15+ years old now, even though he isn't having ignition issues, I don't see why he can't run 0.8mm gap. Wouldn't make much difference between 1.1 and 0.8 on N/A anyway. You don't need to gap down the 0.8mm version since it's already made with that gap. OP can try both gaps and heat ranges to see if it makes and difference. That's why I recommend getting the copper ones, $3-4 vs $15-20 per plug.

I've been running BCPR6ES on my R31 for 5+ years without issues. Ran both gaps and didn't make a difference.

Also, servicing the car isn't any different than servicing a non-Skyline. Oil + filters. Do the spark plugs and air + fuel filters if they haven't been done this year.

Oil filter - use Nissan (don't know part number) or Z145a.

Oil - whatever you like, but something like 10W-40 is fine (support Aussie brands, Nulon or Penrite).

Apart from the consumables, you'll need an oil pan/tray, 14mm spanner, filter opener thingy, and optionally a funnel and jack. Oh and rags, they come in handy. Remember to do up the sump plug before filling it with new oil.

PFR5G11 NGK platinum is what i used on my old Rb25de, had better fuel economy as well as much better idle. Also cleaned out the coil packs and vaccumed the debris left over from the previous plugs before installing the new ones ;)

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
