Im just finishing up the build of my 3vz-e. I have bored the block .030(from the engine shop), new crank, bigger doa cam, bigger pistons, new rods, new exhaust and intake valves, cleaned up the heads and everything, ported them, and new injectors. I also put a Centerforce Stage 1 clutch in it too while I had it apart. I already have 2 1/4" exhaust, no cat, 40 series flowmaster. When I get it done in a couple days, I want to put an intake on it that is the toyota adaptor plate, and a open cone filter, just gets rid of the box. I was wondering if anyone has done this on there 3.0, and how they did it? What tubes do you have to plug off, or what not? Also another question I had is what kind of oil should I run in it now? Its going to be BRAND NEW, and I was wondering if I should run a full synthetic, or what? Or just stick to the good ol' castol syntec 10-30? What would I gain/lose using a full synthetic oil? Of course I would still use the toyota oil filter too.
