Not unless you want to open up the bottom end and check your rod bearings for wear. In the past, there have been a lot of cases where somebody put a DET in their SE-R and it spun a bearing a couple weeks (or days) later. It happened to me once, and it's happened to other people I know.
Conventional wisdom on this issue is just to replace the bearings with new ones when you get the motor, before you install it. It could save you the pain of replacing the bearings later after the motor is in the car. On the other hand, there are a number of people who have done the DET swap and had no bearing troubles. I tend to see it as Russian Roulette.
Other than that, you should be okay, assuming you check the engine over for obvious stuff like damaged hoses, distrubutor cap and rotor, plugs and wires, that sort of thing. If you're going to use the stock turbo for a while, check the turbine shaft play. If it moves around noticably, then it'll probably have to be rebuilt. if it moves very little, then you're probably okay.
