Strange engine noise while accelerating

Ive posted a video on you tube, called 'nissan pulsar funny noise under boost' have a listen see if anyone can put there finger on it. I have recently changed turbo and injectors then after this started, changed the plugs, may do the ht leads next. But ultimatley im guna get a z 32 and a remap but dont want to if this wont solve the problem.

Sounds like hesitation/missing, could be loads of things, check the turbo to solenoid piping, what boost are you hitting?

In the video im on low boost which i think is like a bar or just under but if i put it in high boost its much worse, maybe ill change the leads see

What plugs and gapping you running

Had NGK-R before but they got wet from water getting in the vents so i bought some champion ones not sure on them just the ones the book said in the shop.

Could be your plugs then, I'd change them for some bcr8es

worst plugs in the world are champion
get them out and put some descent plugs in

well im finding it hard to come across any others i dont want to go on fleabay cos you never know what your guna get ill google them other ones see if i can find them

The NGK BCR8ES are a fairly common plug, you should be able to find them easy enough and they are usually only a couple of quid each

Yeah cheers i just didnt know the name first place i rang had em on the shelve for £2 each....bloody typical the champion ones were twice the price. do they need re gapping or are the 0.8 already?

I bought some listed for an aston martin v8 vantage because they came pre gapped to 0.7 if I remember correctly.

I got 8 for £16

The ngk are the ones i have, and loads cheaper than whats usually listed

gap them to .7

ok cheers

try them and report back

My plugs came in a box but with two missing lol it was advertised as 8 though so I can't grumble, still a spare plug for each cylinder and at £2 a pop they're very reasonable

yeah will do i cant get em till 2morrow tho but ill put them in thursday night

Ok so ive changed the plugs, but while i did i took the coil off which for want of a better word is fucked all corroded on one side split expanded you name it its got it. So ive orded one off Bob and i shall report once changed!

Right i changed the plugs gapped to .7, this didnt help but then i changed the coil which was rusted expanded and basically fucked and yes its solved the problem. Cheers for everyones help, got a z32 delivered last week just need a map and we should be somewhere decent!

Glad to here you've got it all sorted mate

glad all is ok! i think i might have the same problem with my R!

yep glad the coil sorted it for you mark   

I've had the same problem with my R on an airfield the other day. It only does that when hot but the spark plugs ive fitted are some shitty ones so ill change the dizzy and arm, cables and sparks! should be all good after that

Hiya mike what plugs do you have already in them heat range ????
