Happened to notice that when i rev my ek9 (stock b16b) whilst the car i still , at high revs there's smoke behind the exhaust.

The smoke behind is definitely not burnt oil as i check it every time and it seats where it should. Lately been driving the car quite hard.

It uses motul 5w40 8100 oil with greddy racing 07 spark plugs.

Car's got 5zigen header , decat , Trust n1 exhaust system + a fujita cai.

Temperatures here in Cyprus now are a bit crazy , and i don't know if that's the cause. around 28-30 deg Celsius at night with unimaginable humidity.

Any thoughts ?
 
Is the car hard on fuel?

I wouldn't be running racing plugs on a standard engine. It just seems like overkill IMO. Try standard NGK BK7RE-11 plugs and see if that helps.

It still sounds like oil to me. But try the plugs first
