The Corolla pings, you wanna tell me how to stop that now!

Don't care anyway, it made it tyo Albany and back on Friday so if it blows up I don't care, put a new motor in it!

Are you all talking about Adam's car pinging on the dyno the other day?

Paul has had his rage problems all his life!

adam,

if you don't have larger injectors or if you haven't increased the fuel pressure via rising rate reg then you can expect problems at power levels you are reaching. you may find that one piston is responsable for the ping as well, due to a partially blocked injector or something.

Here's one more idea to try:

Run a set of 7's plugs if your not already.

    • Thank you for the feedback bro. Looks like it’ll have to stay off the road till it gets an ecu 
    • Only if you do not You will not be able to drive it with any serious load without risk of it pinging, which will either slowly or rapidly kill it, depending on how bad it is.
    • Hi guys, I’m new to the GTR scene. Picked up an R33 GTR earlier this year that needs a lot of love. I’ve been going through the hot side, changing all the gaskets and while it was all off I managed to score a set of -9s. It still had the stock ceramics so I was pretty happy to get the 2860s.  I live in a small country in the pacific with 0 performance car scene. No dyno’s no performance parts, let alone stock parts for a skyline. I order everything from Australia and do it myself. This means I’ll be running the stock ECU. Maybe down the track I’ll get an aftermarket set up and do a remote tune.  Will the car run -9s on stock tune safely?  I have a very heavy foot so I really hope so 😂   thanks guys   
    • perfect, no rush to address the leaking bush then, it's not doing much/anything
    • I'm not sure if it will bolt up, but.... I'm reasonably sure that the ID of the runners is somewhat smaller on the NAs. So it probably wouldn't be a good match at the flange where the top and bottom meet. So that would be a reason to not do it. And the skinny runners would be the bit you're keeping, which would be a reason to no do it. You'd want the big runners if you were doing any work to swap stuff. Why not just use what you've got, like nearly everyone else who has +T'd an NA? You don't need or want the TCS throttle or other stuff that is specifically DET inlet/crossover.
