Spare set of twins!
I have a spare set of twins with no shaft play on them and a nice manifold with really minimal cracking. Now my question is, is there a way to tell if these twins will leak oil or leak coolant with out installing them? Please help thanks

Not to my knowledge. I asked Bryan at BNR Supercars this question once, and there's really no good way to know. If the turbos have a lot of burnt oil on the turbine wheel, that's a sure sign it was leaking in the past.
As far as leaking coolant, that's much easier. The coolant lines to the turbo just run around the turbo's cartridge to cool it, it's impossible for it to leak into the turbo. If you would have a leak it would be external around the banjo bolts holding the coolant lines to the turbos. But, this isn't a common spot for leaks. You could pressure or vacuum test the coolant lines by capping one end and applying pressure or vacuum to the other - if it holds, you're good.
