B&M 70270 - B&M SuperCooler Oil Coolers
I don't know what core that is, could be a great one, could be crappy. The Setrab cores that the Stillen and Nissan Motorsports kits are using are a solid, well-proven design though. Also, that kit looks like it uses plain rubber hose. It will "work", but personally I wouldn't trust a plain rubber hose for something as critical as oil cooler lines. If they burst, or a cheap hose-clamp connection leaks or breaks loose, or something rubs on them and cuts them, or even wears a weak spot in it (leading to a burst)... it takes a very very short window of time to destroy your engine once your oil starts dumping on the ground from such a failure. Good quality hoses (and attention paid to the details of routing and protecting them) are a must for an oil cooler.

In a somewhat related incident from my past, I once had a transmission cooler on a TH400 auto tranny on an 81 Firebird that was run up to the front with rubber hoses like that. A few thousand miles after install, when I was pretty confident it was holding up well, I was on a long highway cruise in the middle of summer. Running down a highway between towns with no exit or service station in sight, one of the hoses blew out. I heard it and immediately shut the car down onto the shoulder and turned it off, but it wasn't fast enough to save anything.

2 Hours on the roadside waiting for a tow truck, a *long* tow back to the nearest large town, and refilled the fluid, but the tranny was dead. Had to do a complete rebuild on it.

Moral of the story: don't skimp out on hoses and connections for critical fluids.
