lol, if I ever made a complete kit, it would be way too expensive for the *frugal* Nissan crowd

Plus, I dont ever want to deal with hose and hose ends....way too many combinations out there for each particular setup.
Besides, there is a really good selection of remote oil filter mounts with -10an oring fittings on the market...Perma Cool has one of the better selections for not too much money.

If you want to be a baller, and add a lot more oil to the system, get the dual filter mount and run two filters
The best oil coolers ive found are made by Perma Cool again, these are trick and keep the 5/8 bore size thru the entire system, keepig your pressure loss to a minimum.
