Wogpsi - are you sure l can run oil drain to oil filter sandwich plate adaptor? Because even on the website it says it's pressurized and that's only for oil feed not oil drain? or am l wrong

you can use for both, there should be a in and out

Do u recommend the 90 degree sump adaptor or the sandwich plate for oil drain? What do you commonly use? ---------- Post added 02-03-12 at 01:00 ---------- Can l use both heater core hoses for water? One for feed and other for return? I wud assumeone of the hoses are pressurized and other hose not pressurized?

Or just run a dry setup Some original photos have not been recovered yet.

So, after a bit of searching, ive found that any RB block off sandwich plate will work (the GREX greddy ones look pretty decent), if you remove that threaded part that sticks out (which attaches to the standard oil filter) and use a gasket (justjap or nissan have them). Seems interesting that nissan left the 4 bolt holes for the RB25/26 sandwich plates on the casting for the RB30 block.. http://justjap.com/store/product.php...cat=265&page=3 (http://justjap.com/store/product.php?productid=18637&cat=265&page=3) Thats the easy way if you want to run a return there using an RB25/26 sandwich plate. Otherwise you can use one of these if you have an external pump http://www.ebay.com.au/itm/UNIVERSAL...#ht_2378wt_861 (http://www.ebay.com.au/itm/UNIVERSAL-OIL-FILTER-RELOCATION-KIT-OIL-FILTER-COOLER-SANDWICH-PLATE-ADAPTER-/260917106482?pt=AU_Car_Parts_Accessories&hash=item3cbfdf1732#ht_2378wt_861)
