R33 Rattle (pinging) :unsure:

[proRB88]

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

you sure it was pinging? What fuel are you using?

[proRB88]

not to sure like i said it's not mine yet, but i guess he was using 98 octain, but dont quote me.

[Ultimategtr]

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?

to be honest

blow that car off n go get something else

im sure you can buy a decent car without worries and trust me MORE worries will come later on so look for something that you know works!

how much is he giving it for?

he wants 16 for it, i took out a friend to see it to and he too said the engine sounds fine, but yeah im worried abou that rattle!

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

[burgO.]

IMO it sounds like you were labouring the car by having it in a gear that was too low and the rpm was too low but im no mechanic

[RBwhatever]

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,

[cosworth1971]

3rd is the worse gear for load and whats ur timing say?could be lose parts or bolts too

[RBwhatever]

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.
