R33 Gtr Missing At Full Boost

[jdonly12]

Hey guys my gtr is running like a pile of crap I didnt drive it for a few month and thought it might have been bad fuel.Tried fresh fuel (bp ultimate)and no good,and then put in new platinum plugs and still no good.It runs fine at three quarter throttle but misses bad at full throttle until it hits seven grand it then runs fine till well over 8k

Could it be plugs/gaps or coils

Thanks jd

Well over 8,000? I hope its not a factory motor.

You have a few problems.

1. Bad plug choice, most likely they have fouled again. Go back to $4 copper ones.

2. Sounds like coils or other ignition related issues

So two things to fix - forget plati plugs. Waste of time and money.

Hmm bugga,thought plug choice was bad.just funny it clears up at around 7 grand and runs through till around 8,500rpm

Yes standard motor

Im pretty sure it used to hit the limiter at around 8000rpm,not sure why its revving out further now.

Might have to look into coils,bugger it

On factory turbos you wont be making useful power @ 8000rpm anyway so stop with that.

Especially 8500rpm, not a very wise idea at all mate.
