LOL @ the people saying it'll crush up/burn...

1: It's the end of a spark plug. It won't burn

2: While it's being "crushed up" it's being slammed into your bore and gouging the f**k out of it...

3: When it reaches the head side of things and gets to the valves... Even more trouble...

I have a piece of piston come loose and "crush up" in my motor... It took everything out, lost compression through the bottom end, and also smashed valves... And the only sign? Masses of blue smoke on throttle, and a lumpy idle.

yep . thats it. valves bend easy. mate did the same thing. hopefully it hasnt scored the bore/ damaged a rings. good luck buddy. feel ur pain

impossible unless you fitted the wrong plugs (projected type), skyline plugs MUST be BCP type.... we use BCPR7ES, i see alot of BKR plugs in rb's and they are also WRONG.

The porcelain makes nice divits in the head and piston which in turn cause hotspots and promote pre ignition (pinking)

whats the difference between bcp and the bkr7e's everyone was raving about for a while, do they sit too far down?

Hey dude, Sounds like this car is not your daily drive?, so its easy then jus get a good VAC borrow (pay) from a good engineering shop, Clean it out as good as you can by using a fitting with a hose end for the vac and screw it in to the spark plug hole, then just start it and run it, You've already started it a few times anyways if it runs take it for a drive see how it is then jus do a comp test it'll most probably run if not it needs a to be pulled apart shit happens.

jus do it, ya live n ya learn.

this i would like to know too (sorry to go offtopic)

just got bkr6eIX plugs for my 25... 3 tuning companys recommended them rather than the bcp's.

As far as i was aware it's just a slight difference in length on the top of the spark plug (going into the coil pack). The BCP is higher and makes a better contact, the BKR sits lower. I've used both on many occasions and never seen any difference.

I'd like to know more on what Trent is talking about. Maybe the BKR's are a bit more prone to missfire due to the contact point.

rb love a bit of ceramic

i only found out i droped some in after starting the car and freaked out about the noise

like i said no compression for 2 minutes

though i had gone so far so let it ide for a few more then suddenly the noise disapeared and i had compression

i dont recomend it but hey if your f**ked it you need to pull it appart .. in my case it wend for another 10000 km and didnt really need a re-build.

in other news after rebuilding the engine i was so wasted that i droped it form about 1 metre up and smashed the sump, while i was loweriung it into the engine bay... i was dancing to a good tune on the radio... which required a new one

lol

in say that...the above the engine is still living making 400 + rwkw to this day

good times

it can completly ruin your engine. i had that happen to my old fj20. id got stuck between the piston and bore. 2mm grove in the bore. complete throw away.

you really need to use a bore scope and make sure you get it all out. or pull the head off. you may be able to blow it out with compressed air but make sure the exhaust valve is open, not the inlet..

actually i did try and blow it out for about 30 minutes when i discovered the lack of copression..... good idea

Dude... don't touch it. Get it towed to a qualified mechanic!

Seriously... if it comes out with the oil, it's waaaaay too late.

how do you manage to break ceramic off plugs when changing them? I just can't see how you can do it unless things are getting really crazy when you're under the bonnet

hahahaha +1

got any more news on it mate... sorry 2 hear aye :down:

breaking the ceramic part off a spark plug is probably the most common problem with noobs playing with engines. if you dont have the proper tool to get the spark plugs in/out you can warp it in a big way and the first thing to go is the ceramic part. just using a deep socket isnt good enough unless you know how not to fuck it up. but you guys are pro's right?

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      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.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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

      By Duncan · Posted

      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...
