I sure hope you are right.
The draining is definately a problem. I was hoping to eek by with them..
When I was first building the set-up, with the engine still out of the car, I was told by an unnamed turbo place in San Antonio that I needed -6's at the pan. That's what I welded in for the drains.
It wasn't until after the entire thing was in the car that I was corrected. So my current drains are 1/2" to -10 lines all the way down, but they reduce to -6 at the pan. I was hoping that the oil would be reduced by then and I could get away with that, but obviously not. I'm pulling the pan anyway to address a couple other things so I'm putting in -12 as overkill, and still planning on using the -10 lines. But if that doesn't work at least I won't have to pull the pan again to go to -12. As you know, it requires a bit of work to lift the engine enough to get the pan out.
It's just another lesson-learned in the process of building this car. The sooner I can get the car back up here to Dallas from my house in Austin, the faster I can get it done.
I'm keeping the blow-through for now and addressing some other issues, like this, before going EFI. The expense is pretty great for that swap. I'll be happier with some Fikse's and an intercooler first. Crazy priorities, I know.
I always keep Lateral-g posted first, so stay tuned.
