well see, i have heard you should use a thicker, since things are going to get hotter and not wanting the oil to thin out while in boost? blah blah blah, you know the talk.

also, most my friends well there muscle heads and build small blocks and big blocks. they run diesel oil while breaking in (500 miles) then they go to what they would use on a normal bases..

i would totally agree on this cuz diesel oil has more additives/detergents.

any one else agree/disagree. can i get some input.

its gonna be my first time building (I have helped, but nothing for a boost app. or a 4 cylinder), how much boost would be recommended with out having to sleeve the block.

Mmmmm, i think that's it. i want about 300 out of an LS i don't think im missing any thing.
