The best timed bad thing to happen in the history of bad things.
So I was giving the Integra an Italian tune up when I noticed that it’s starting to make a pinging sound. At first I was on some rough so I though it might be something relatively innocuous, but I soon confirmed it sounds like someone rattling a coffee can full of BBs; plus it only happens above 4.5k rpms at more than 3/4 throttle.
Now what’s the primary cause of pinging? Carbon buildup! (I’ll actually take it to a shop to have them scope it before deciding anything.) Now where is one place carbon buildup takes place? The cylinder head! What’s one of the differences between a LS and GS-R Integra? The cylinder head!
Also of happenings, my brother is deploying in the fall and has asked me to keep his car for him while he’s gone. I haven’t ran this by him yet, but I’m sure he’ll agree.
I add myself to his insurance, pay it, and daily drive his Hyundai.
I leave the Integra with my Mom or Uncle and get to swapping the head, re-ringing the pistons, and probably engine bearings. As well as swapping the ECU to a GS-R one and possibly OBD-II too!
Or should I just start putting 91/3 octane in it (which I’ll do in the meantime anyway) and don’t worry about it?

The obvious answer is to k swap it

Odd.
1. Carbon build up happened on old carburated cars through 60's. I can’t imagine how you could accomplish it in modern fuel injection cars.
2. My ‘07 Si pings on regular. If better fuel makes it go away, that is your problem.
I believe one of the benefits of a EGR valve is that it mitigates pinging. So check to see if it is plugged or disconnected. See

Here is a good discussion I googled EGR Pinging.

Not if you use a K20. It’s 1998 cc.

Buy the gas. You don’t want to rebuild an engine unless you absolutely have to. It sucks.

I will in the meantime, but if I have a backup car to DD; why not go for V-TEC yo!?

Thanks! I’m still going to check for other causes (timing, fuel delivery, etc) it’s just if it turns out to be carbon buildup this is the plan. Although it’s rarer on FI cars, it can definitely happen on higher mileage ones.

I will, it’s just if it turns out to be carbon buildup AND I get to DD my brother’s car. Then I’ll maybe do this.

nothing wrong with wanting to go for the vtec..... you might could start making a pile of parts in the closet in the meantime....... its sort of like a savings account.....

Modern DI cars can build up carbon like CRAZY. Worse than any even marginally-tuned old car with a carb.
On the other hand, older cars with intake manifold fuel injection will probably run almost entirely trouble-free (in this regard) until the ECUs die.

Well played, though it applies to a direct injected Audi and this is a ‘90's Teg. The carbon I was thinking of was inside the cyl. Even with DI, I don’t think carbon forms inside does it?
