Where do you stop improving is an infinite moving line. The dry sump would be a nice addition but will be a difficult install if you want a 3-stage pump or larger. Even if you locate the pump where the AC was, there’s not much depth before you run into headers. Then there’s hose routing in that area and room for plumbing the pan, or placing the reservoir that is supposed to be above the engine. Drive belt modifications, hose and fitting costs, and you still need the oil cooling. I’m not knocking a dry sump, I would rather have one then what I have now. The deficiencies can be solved with an OE style pump, but this is also expensive and work intensive.
The oiling system:
Starts with the valve cover mod on early engines.
Removing both valve covers
Removing both valve cover baffles
Tapping both covers for fittings
Adding a bulkhead fitting to one cover
Replacing the baffles
Replacing the covers
Making the hoses to connect both covers
Installing a breather
Making a hose to go from the top of the front cover to the breather
Removing the oil pump
Ordering a new pump housing (or live with the used housing)
Ordering new and improved oil pump gears
Building, Checking and installing the pump assembly
Replacing all the O-rings for oil transfer and maybe your pick-up depending on the history of the engine.
Removing the oil pan
Developing a baffle system for the pan
Buying an oil filter relocation adaptor and installing it
Buying an oil cooler and installing it
Buying an Accusump and installing it
Buying a remote filter adaptor with flow control and installing it (C&R)
Cut some holes in your NSX
Make 12AN hoses to go from the adaptor to a “T” fitting
From the “T” to the filter housing
From the other “T” to the Accusump
From the Filter housing to the cooler
From the cooler back to the filter housing
From the filter housing back to the engine
In my case from the Oil cooler to water
From water back to the oil cooler
This is a good example of why racecars get so expensive; this setup would cost you over $4000 to duplicate if you did the labor yourself.
