ITs either PINGING or theres something lose in your engine bay. Last time i had this problem is my turbo heat shield was loose, so whenever I give it a go the engines vibrates so does the heat shield agianst the turbo. Try looking at your engine bay for anything loose and tighten it. If it still persist look at your spark plug maybe ur car is pinging. Gud luck let us know how u go.

i lost my licence for losing all my points on my p's in a SSS pulsar and found out about the suspension the day after picking up the skyline. i had my dad drive the car every few days for the 3months i couldnt and it got fresh fuel in the day before i got my licence back shell vracing 100octane i had it dyno tuned the day i got the car and i know my dad hasnt had it over 3000rpm when hes driven it. im gonna check for any lose things in the engine bay in the morning hopefully that will fix it.

i know speeding and drifting is illeagle so why is it so fun?

all the fun things are against the law :)

but what did he get tuned?

he hasnt got an aftermarket ecu, judging by his description, its virtually stock.

i had this problem when i chucked in 100octane in my r32 before i got the ecu remap and it pinged.

obviously the ecu didnt like the 100 octane, and its doing the same in his car.

is this true, can the wrong fuel cause a "rattle" noise in the engine bay? i've got a similar problem on my r33 rb25det.

the noise sounds like its coming from near the turbo area of the engine and it's really struggling to keep revs at idle but at high speed it feels fine.

problem seemed to start after filling up with Shell V Power fuel 99 Octane and after it got tested on the dyno, so hopefully it'll not be anything serious and maybe just a loose heat shield etc but that doesn't say why it is stalling?

any help guys PLEASE? :ninja:

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
