Hey, just did a swap on my 240sx and just wanted to know what kind of oil would you recomend using in S13 redtop Sr20det wth a T28 Tubro. I know someone using 3 bottles 20w-50 and 1 bottle of 10w-30 its Royal purple but i heard thats to thick and may delay the tubro from spooling up by 500rpm. really appreciate if someone could anwser my question.
thanks
