Could you send a pic for example. I'm not sure if mine is a neo or not. Previous owner said it was but don't know for sure. Don't wanna get the wrong get neo ones if the engine isn't actually a neo. Engine has been swapped

Gonna try some splitfires to see if that fixes. Do the rb25det and rb25det neos coilpacks work with eachother or do I need to get the neo ones coz my engine is neo (which I was told)

Sorry guys had a lot of work and never got around to doing so. Took out and clean sparkplugs. Gapped to 0.6 but problem still consists. (Car idles a bit better but still original problem is there) But found something weird. When driving if I give it hurts and bang off limiter a little bit the misfire seems to go away for 5-10 mins and then it's back? Really confused

Which do you recommend for my setup?

??

I'll do that tonight and I'll let you know the results. But may I ask what does the gap difference do to help? I'm far from being a mechanic aha

Idk the brand but this is them

Fuel is 98, fuel pump is new and so are coils so I'm guessing sparkplugs

I'm not sure what sparkplugs are in the car. Or coilpacks. Bought the car with them in. Also I would turn up boost but it has stock bottom end? Wouldn't it blow

1999 Nissan Stagea (rb25det non neo) is an RS so is factory RWD. has been manual swapped using an R34 GTT box Need help before I take to mechanic as could be a simple fix. When driving normally there isn't a noticeable misfire. But when on boost, especially as soon as boost starts to just past half max psi the car stutters coz the misfire but continues up the rev range. Usually it's once or twice when I floor it but sometimes it will misfire alot when on boost. Cold or warm it happens with both. The more I drive it the worse it's getting and have no clue what it may be apart from maybe sparkplugs but it's fine til it hits boost. Also on idle it runs a little rough. Anyone know any possible solutions or possibly what may cause this and what to check.
