Noise At 5500rpm

[Clipse]

Friend has a series 1 R33 Skyline manual. In say second gear when he takes it to 5500rpm its making a continuous popping noise (sounds like its coming from the exhaust) any idea as to what this is and what it could mean???

Certainly sounds like coil packs to me. Is it like the engine is stuttering? Keep accelerating and it goes away?

Heres another thread of a similar problem, have aread

Yeh happens to me too, changed the gapping of the plugs and it was ok, but if its not that, then its the coil packs

boost cut

I had a slight poping sounds when i boosted just over 12.2 or 12.5.. i think i hit boost cut... then i turned down a little.. so it's between 11.9 to 12.1 n it's fine

What's the average cost you're looking at for coilpacks + installation? My skyline stutters throughout the high boost rev range, and as I have stock boost I doubt it's boost cut. It's not a big problem atm, but it would be better to have smoother power delivery.

Hey mate i had the exact same problem with mine, was a nice smooth drive until i planted it, was alright at the lower rev range then wen it hit boost it was pop pop pop out of me exhaust, had stock boost, regapped the sparks, cant remember what else i did but nothing helped, if you have the stock coilpacks ide be getting some new splitfires!

Put the coil packs in and runs spot on again.

Yeh i agree dont pay much more than $500. for the coils and installation, if you shop around you'll find it for that price if not cheaper.

Good luck mate
