I am getting knocks of upto 120 under boost .. not all the time but i do get knocks.. mostly i get knock when i boost for the first time.. that is the highest value i get... then afterwards i do still get knock but below the numbers i get the first time...

Just to refresh and remind and tell the people who do not know... i am the guy who had given up completely on the rotary and even have got 2 sr20dets and a 1jz-gte but as ppl had told me to give the rotary a last chance i have and it runs great otherwise... just having trouble with the knocks... its a new engine not done more than 800 miles... can it be that the clearances are a wee but too tight and it needs more running in... anything i should check... i get knock mostly at the time when the secondary kicks in...

please advise
thanks
