Hey guys

I'm about to be the pround owner of a 1993 r33 GTS-T. I took it for a test drive the other weekend with my dad, and found that when i was a a low RPM the car was pinging, it only happend once when i was taking a corner in 3rd and you could hear a really loud rattle i spoke to the owner who is a machanic and he told me that, thats a usual occurance with these cars when in a low rpm, and it is betta to shifgt down and stay in higher rpm range. But i spoke to a friend about the car and he told me it is very un-usual for a car to ping at low rpm speically if there is really no performce mods on the car (3.5 inch dunp to a high flow cat, with a 4inch cat back to a 5inch cannon, and a front mount intercooler)

So i was wondering if anyone can tell me if the problem is something that i should be worried about and, not get the car or like the machanic said something that happens with these cars.

Please help me out i really dont want to buy a mellon, and never hear the end of "we told you so" from my rents. lol

Best regards

Vlad

(sorry about any spelling mistakes)

Farrrrrrrrrrrrrrrrrrk man 3.5inch dump and a 4inch dump??? you sure the noise levels legal in your state???

i have a 3inch dump, 3.7inch catback and its f**kING loud. lol

i wouldnt think its pinging tho... when you say low rpm, how low? as in under 4000rpm? it could be ur plugs... cos rb's run rich when more boost is added.. maybe clean your coils and check for cracks?

when you heard the noise were you in third gear and was the engine revving under 2000rpm, mine makes a sort of rattling noise when doing this, im not sure why but i dont think its something to worry about

that was spot on, i was in therd taking the corner and it might of been 2,000 RPMS or under when the nosie started, then as soon as the revs got up it stoped.

So is it something that i should be worried about, or just something that happens with these cars?

lol i got no idea, i was just wondering if it was the same thing mine does, i thought it might have something to do with mine having a nismo GMAX twin plate clutch and a short shifter, but generally if i know its going to be revving under 2000 in third ill change down to second (unless im feeling lazy)

it doesn't seem to affect the cars performance at all so im not really worried about it. hopefully someone else knows if its bad or not

Yeah 3rd in a corner is to high a gear if your going slow enough. You've probably just put a lot of load on the motor trying to move it at such low speeds under a certain amount of rpm. Don't worry about it the car is fine. If it was pinging at high rpm, then I'd be worried.

Thank you all very much for the advice, i have just put a down payment on the car so hopefully i should be getting it soon, and asking "what mods should i start to do to it" lol

once again thank you

its weird tho cause it only seems to do it in third, meh,

Not necessarily. It'll do it in other gears to given the chance. eg. Driving up a hill doing about 60kph and putting it in 5th gear will put the car under load and will make the same sound. It just so happens in his situation he's in 3rd gear going even slower, probably more like 20kph around a corner and revving under 2000rpm and trying to accelerate thus putting the car under load.

Mine does the same... Anything low and the whole car sounds like it's about to fall apart. I found originally that the stock heatshielding on the stock exhaust was loose and making the problem much more obvious, so I removed it. Now the sound is only coming from around the front.

As soon as the revs are up a little more, whether you are booting it or just cruising up to speed) it goes away completely. I *DO* find though, that it happens MUCH more easily when cornering.

Every morning I pull out from my street in first, and shift to 2nd as i'm turning, or I just turn in 2nd if there are no cars and I don't need to stop... this makes the noise every time without fail. I think I need to keep it in first while cornering, with lots of go, and some opposite lock. =-/

I had a similar problem on my 32 that occured around the 2200 mark. I found that it was one of the heat-shield welds on my metal-cat cat converter had broken and was causing it to vibrate. However if you are suss on the car don't buy it. There are plenty of others for sale.

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
