Need Help With Rb Greddy/grex Oil Cooler Kit

[UCF10]

ok so i've got an rb30/26 and just bought greddy oil cooler kit with the grex thermostate and im not running the relocater kit, i have it all fitted but my z145 is to wide hits where the angle come out of the thermostate for the fittings, thread is right but the filter is just to wide, what i want to know i read that a z445 oil filter is a bit smaller filter, can i use this filter on my motor? or anyone else had this problem or used a different filter, car is making over 500hp and dont want to have an oil problems with it...... thanx liam

Z442: http://www.rycofilte...ULSAR/part/Z442

Z145a and Z442 have the exact same thread "3/4-16-UNF-2B" while the Z445 thread diameter width is the same, but has a longer thread "M20-x1.5-6H".

I think also (from vague memory) the Z442 doesn't have a drain-back valve but someone else can correct me on that, while I'm pretty sure the Z445 does have a drain-back valve.

Because the Z445 has the longer thread, I've read of instances where it has popped off, but I would be checking with that particular kit if it recommends an Z445 equivalent.

I have the same oil cooler kit on my 32 GTR and am using a Ryco Z131A which has a anti-drain back valve

The Nismo ones are alot smaller diameter, probably 10 times the price though

I've been buying the Nismo ones for NZ$30
