Oil pump, Volume or Pressure?

[Big Country]

If this question has already been asked then I apologize in advance, but I did a search and didn't find what I was looking for. My question is in regards to after market oil pumps. What I have found out this far is that two options exist. The first option is the High Pressure Oil Pump from Driftmotion. I have been told that high pressure systems are bad on the turbo’s seals. Is there any truth to this and if so is there a way to regulate the pressure going into the turbo? The second option is a low pressure (I.E. factory), high volume oil pump made by a company called Toga that I found on Horsepowerfreaks.com. While this sounds good, the factory pressure on the 7m makes me nervous, especially when these motors have zero tolerance for low pressure conditions. What I really want to know is if anyone here is running either of these setups and whether or not there are any reliability issues?

thanks and sorry. Have you heard of any problems when going with higher pressure, like blowing the seals in the turbo?

"high-pressure" should be the shimming I suppose? Then no. Plus, if we're talking about DM then I think Aaron knows his stuff and he would't sell the thing
If you haven't then I'd advise reading the stickys here (I'm guessing you're building an engine )
