i was giving my car a bit of a go today cos i got my licence back yesterday. and when i got to abou6500rpm with foot flat down trying to push the firewall out the car(lol) there was a rattle from the engine bay im running stock boost with exhaust and pod filter can anyone give me any sugestions where to look to fix the rattle

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:

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
