Will a oil cooler sandwich adapter for a type r fit on a gsr b18c1?

 

the adapter bolt that is

 

You'll have to get the part where the oil filter threads into becuase the length will be different.

 

Yes. All Honda's share the same M20x1.5 thread size and pitch.

However, you have to be careful of which plate adapters you use and for what applications. There are sandwich plate adapters and oil input adapters.

Sandwich plate adapters have to have an OUT and a way back IN to the sandwich plate adapter. If you try to use just the OUT and plug up the IN on the sandwich plate adapters, the only oil is getting back to the engine is through a tiny bypass check valve.

Oil input adapters don't need a way back in through the plate adapter. They can dump wherever you want. GE's VTEC/oil feed adapter plate is this type.

If you really do need a sandwich plate adapter, then you might run into some issues with the adapter piece being too long and not being able to put enough of any compression on the plate adapter to get the o-ring to seal. Perma-cool, Earl's, TVD (sp?), and a few others sandwich plates I have tested have this problem.

 

Thanks for the info, yeah i had a oil cooler mounted on my old car and had the same problem, had to cut the thing to size. Just lost a auction on a hella nice oil cooler system from earls, too bad the auction ended 3 in the morning else i would have won it.
