whats up guys need a little help. Didn't want to make another thread on this being that my question has already been brought up. I have a fully built sleeved K24 with a Z1 head, I am about to strap on a GTX35r on it. The motor has about 1800 miles on it since the build. I've been using conventional oil for the break in. But now the question is what brand and what weight do you guys recommend for me to use now me being boosted? I have used brad penn 20w50 in my fully built 720hp evo, it was pretty good. Lots of evo guys use it and love it. Now I'm not sure if it was on here or k20a, I seen someone say that they use brad penn 20w50 on there boosted K and recommend it... what do you guys think? need a little help especially that my eg is almost done... thanks any input would be appreciated..
