Yes, oil only. My thinking was that where the truck isn't my daily driver I can get used to letting it idle for 30 seconds or so before turning the engine off. I don't expect to run the truck/turbo hard so I am thinking I can get away with an oil only turbo. With the turbo will be an intercooler and I'm hoping to get away with stock injectors, maybe a supra fuel pump and stock ECM. With that being said, would the 60-1 be better?

I think they will both do fine. note there is not much diff at all. Use either
the .81ar is probably the best (works for me) choice but who knows for sure
most of those turbine housings have a couple plugs that can be removed to run water lines. My old housing has them. running water lines is probably on the bottom of your list. If the motor still lives 10 min after build start up then worry about water lines.
And I passed smog with mine only last week

Interesting exchange. Sounds like too much to know for just one person.
Someone would definately have to know that they are an expert to be a know it all.
Turbo or SC? I don't know. I'm leaning toward the S/C but primarily because it would be easier for my simple mind to grasp and easier to install. It's apparent to me that if I really wanted more power I would start to bone up on installing a turbo.

The hard part is probably over. That's the sizing issue. We've got a few here that should work fine and hopefully mid summer we will have a good shopping list for others to follow.
The safe bet is to go with what AVO used but I'm leaning towards the GT35R. Just getting my head into fuel delivery and as usual it's not conforming to accepted practices right now.
I don't plan on diving in till late next year at the earliest so I will be interested in seeing what you come up with. Maybe you mentioned this in the the thread but are you shooting for a flatter boost curve or are you looking for boost at higher rpms?

I'm looking for boost on the lower end. The fact that I'm running 4.88s will automatically delay the boost as it is.
So basically the smallest turbine that will safely run on the truck for as quick a spool as possible. I rarely go over 4k rpm so high end isn't a factor.
