Tony, I already use an electric water pump and have the OEM pump blocked off.
The chain routing will hit the pump in the OEM location.
The issue is that I dont think I can use a water pump location sump pump without clearance issues.
However...
I can get this dry sump kit for about 1K complete.
http://www.bigccracing.com/shop/product.asp?idproduct=90(listed the 938 sterling is about 1500$)
Downs Engineering makes a belt drive dry sump setup driven off the clutch side:
http://www.downsengineering.com/products.htmlbut their setup is well into 2500$
and....
If I could run any of them it would be the dry sump made by NLR systems:
1700$ for 2 stage 2K for 4 stage....
Also the busa engine uses oil jets on the pistons, mine are restricted to 50% BUT have a good deal more oil pressure/volume over OEM (and many guys run them 100% blocked)
